There seem to be a lot of questions about beginning to autocross. I will hopefully be able to answer a few of these questions. There are many questions on which car to begin the autocross experience.

I will tell you upfront that I am prejudice when it comes to this subject, and I am Mr. Cheapo! I prefer the early SN95 chassis, over the Fox body. There are many reasons for this other than I LOVE the look of the early SN95. I personally like the old Fox body style, (pre-SVO style), better than the later Fox body.

There are many mechanical reasons also for why I prefer the early SN95 over the Fox body. First and foremost in my book are the factory brakes and wheel stud setup on the SN95 over the Fox. The SN95 has four wheel disc’s with ABS and five bolt rims. The Fox has front disc/rear drum and four bolt rims. The cost of the brake upgrade on the SN95 is in the hundreds of dollars as outlined in my ā€œAutocross brakeā€ post and also is an easy bolt-on. The cost to upgrade the Fox to all wheel disc and 5-bolt rims is in the thousands of dollars and takes a lot of tech knowledge and time.

If you move up to the 96-98 SN95 you now get the new modern 4.6 overhead cam engine in place of the old pushrod 302. I will NOT get into a discussion between which engine is better. I’ll leave that up to other posts to discuss the pro’s and con’s of both.

And if you move up to the 96-98 Cobra, you now have 300 HP to begin with, the same as the new SN197 GT’s. This would be an excellent starting point for the beginning autocrosser. This way you will have enough horsepower for many years to come, so you can concentrate on brakes, suspension, etc. and not even have to think about serious engine upgrades. You also will be able to get into a serious car for not a lot of money.

The only down side to the Cobra, is that too many of them have the leather interior, so be prepared to purchase some race seats, or be prepared to slide around in the seat, and don’t forget about your passenger. You have the steering wheel to hold on to, the passenger has nothing. And don’t get me started on the tan interiors, YUCK!

You may also move up to the 99-04 Mustang. The six cylinder is also an option in the short term, you have 200HP, but in the long term I believe you will be better served with an 8. Horsepower is easier to gain in an 8 as compared to a 6. In my opinion you are now talking some serious money when you get into the 2k’s that could get you an early SN95 and quite a few mod’s.

Of course you can move up to the 03-04 Cobra and have some very serious ponies with an absolutely modern rear axle setup. BUT, you are also talking some very serious money, and for the beginner all of that HP under your right foot is asking for trouble. It is too tempting for the beginner to come out of a corner before a long straight, nail the throttle and wonder why he ended up into the wall. With the supercharged Cobra’s you have a slight pause while the boost builds. When all of that HP hits the rear tires they break loose and you find yourself in a heap of trouble with little to no experience on how to overcome it.
I have no problem with anyone buying the new SN197 chassis and racing that. They are a great chassis, if not a little heavy, but we are talking about beginning to autocross and how to do it economically.

You notice I skipped over the advantages of the Fox body, yes there are some. They are lighter than all of the subsequent chassis’. Prices are very reasonable if not cheap. There are many, many aftermarket parts for them. There are many, many years of experience with this chassis. If you hurt it, your pocketbook won’t hurt as bad as if you hurt a newer model.

The classic Mustangs, 64-73, is race at your own peril. There are many people who race these, but they are well seasoned individuals who know their vehicles and the tracks they run on. There are many upgrade parts to install on these as well, but for the beginner, concentrate on the late Fox, or early SN95 for the best bang for the buck.

Convertibles, that is up to the individual. The first thing you need to install is a roll bar. You cannot run events without it. You also need to run with the top down. That is fine most of the time, but remember that means those very hot, bright sunshine days as well as cool rainy days. In heavier rain, it is up to the track steward to decide on that day whether tops are up or down. The chassis on a ragtop is not as stiff as a coupe, but the roll bar helps stiffen the chassis. BUT, remember out on the street depending on the roll bar style, driver and passenger may need to climb over to enter and exit, and for sure it would be a hindrance for rear seat passengers.

Automatic versus stick, the stick is always preferable. I have an automatic and it has advantages. With the auto you can concentrate only on driving and braking, you don’t have to think about clutching/shifting, or missing a gear, the auto is a little better for a novice. But, the first thing I would do with an auto whether it is strictly street, or street/track, is to install a B&M Transpak shift kit. The Ford automatic shifts VERY slowly, the shift kit speeds up the shifts to a more reasonable level. You will find it refreshingly crisp and not at all harsh.

To sum this all up, and remember these are only my recommendations, first choice track the Mustang you already own. Next, 8 cyl over 6, stick over auto, coupe over ragtop. My Mustang choices in descending order with costs a factor. 94-95 GT, 96-98 GT, 85-93 GT, the Cobra models in that same order. When you get into the 99+ models, you are talking more money, but they will serve you very well.

I hope this answers a few questions and helps in your decision making process. So, go out there and have some fun, see you at the track.

i'll agree with the sn95 for road racing and autocross. i see more sn95 cars running american sedan(trans am series) than foxes or even the 05+. the foxes i have seen running AS have their fronts cambered to the max. foxes are also very very flexible. i personally own a fox only because i've wanted one since i was in a diaper. if i were to build a competition car, i'd go 95+ for the simple fact of if you break something, there is more of a chance someone will have the part u need at the track.
 
I went with the fox. Except for the brakes the cars are built around the same chassis right? I would think weight would be the most important. If chassis is a problem can't you put a roll bar or roll cage in?
 
The SN95 is about 75-80% the same chassis as the fox-body's are. The biggest weaknesses with the fox-body are the brakes and the weak frame. Subframe connectors help out tremendously as well as a nice brake upgrade. Doing a Cobra brake upgrade on the foxbody is a HUGE difference but requires a bit of money and know-how. As well as using 17" or bigger rims.
 
First and foremost in my book are the factory brakes and wheel stud setup on the SN95 over the Fox. The SN95 has four wheel disc’s with ABS and five bolt rims. The Fox has front disc/rear drum and four bolt rims. The cost of the brake upgrade on the SN95 is in the hundreds of dollars as outlined in my ā€œAutocross brakeā€ post and also is an easy bolt-on. The cost to upgrade the Fox to all wheel disc and 5-bolt rims is in the thousands of dollars and takes a lot of tech knowledge and time.
The difference in cost to upgrade the brakes and wheels between the Fox and the SN95 is often not much, and is variable depending on the standard equipment of each car.

For instance, I swapped the front of my Fox to 5-lug, 17x9 10th Anniversary Cobra wheels, and Cobra Brakes.

What were the necessary items?

10th Ann. Cobra wheels (17x9)
Cobra Brakes
Stainless Brake lines
96+ Spindles/Hubs

No stock SN95 came with 17x9's (except the R), so if an SN95 wanted the SAME setup, the only EXTRA items I had to buy were the Spindles/Hubs... a whole $75.

Now, the difference in the back will probably be more significant, but the point is, the difference is not necessarily THOUSANDS of dollars or anything like that.

That being said, I'm not saying that the Fox is the better way to go or anything, I'm just saying look into what your plans are, and select the car/upgrades accordingly.
 
Starting with a 2001 v6 stick (with the 8.8... not sure why it's there and not a 7.5, but it's there), assuming bone stock plus a cat back, CAI and tune... what would you're recommendations be for a starting newbie? I feel the 3.8 has enough as is to get me into tight situations as a newbie, but I'm unsure of the "hot setup" for my car's suspention and track worthiness. Expecting the car to be a street car as well, and not a dedicated competitor, where should I start and where should I expect it to lead me? And... is there any web sources that can help me find local tracks?

For someone who is just starting out, I'd start by just trying out a few local Auto-X events to confirm that it's something you want to do for a while and spend some money on.

If it is, and you're looking for a few relatively inexpensive modifications, you can do some mild suspension modifications that will really wake the car up.

For instance, pick up some springs with a notably higher spring rate than stock... Mach 1 or Bullitt will work, Ford C Springs, H&R, etc (Eibach Pro-Kit does not bump up the spring rate much, fyi)... and then pick up some shocks/struts that work for that spring rate. The Mach 1 / Bullitt dampers will work, or you can get some used Bilstein struts off the FRONT of an '03-'04 Cobra and then buy a set of Bilstein HD's for the rear (the Cobra IRS shocks won't work).

As is the case with anything, you can spend as much or as little money as you want...

Good luck
 
I am a beginner in auto cross. I need help with I deas on what parts would fit my purpose the best. i have an 86LX with a carb'd 331. I use the car mostly for a saturday night special but i would love to be able to take it to a course and race it but I am ot doing anything serious. Would a tubular K-member be too much for a car that isn't used like that all the time?? what would be a good strut/shock and spring setup be. I am open to any ideas. thanks
 
I entered my 2007 Mustang GT into an autocross instructional last weekend. It was a tight cone course and man I felt heavy and big out there. Seemed like on top of being a beginner I was also driving the wrong car.

The event was a lot of fun but I got the impression if I really wanted to compete I'd need to get a different car. What are your thoughts on that?
 
mazda or gut your car. Auto cross is like playing chess. Stick to the Nasa events, this is where your car will shine 150 mph on a 100ft wide open track is alot more fun than a 60 mph cone track where you can not pass.
The no passing is why I dont do autocross. You will never get better at real racing if you can not pass. And the pay to drive 1/2 day then work the other half is stupid and not worth the money for the track time. $300 for 8 runs in hpde is way worth the money.
My 2 cents

The first thing is better brakes on that car. Do you have 5 lugs on it yet? The next is SS brake lines, then hawk pads and hi temp brake fluid. The the bang for your buck pad s are the hawk blues. You will have to change them out for race day. The operating temp of blues are not for the street.
next would be a coil over kit or a start on one. The bilstien hds are $500 for a set. MM makes a coil over kit that will fit these shocks and struts. A bump steer kit, and lower rear control arms. The struts and bump steer kit will need to be installed at the same time then get the car aligned.
I beat that is over load. Dont buy a K member if you dont have what I listed above,your wasting your money. Make your car stop good first. The cobra front brake set up is great for $500, then do 94-95 gt rears
 
ok, started doing research now for entering the targa in Newfoundland. I plan on driving the V6 listed here with those mods. My bigest concern is weather or not the suspension, and drive train will hold up. I plan on running some 18X9 rims as well. any thoughts/sugestions

LOL! Do you, by any chance, also race boats?
 
I don't really agree with everything in this thread...

That said, here are two quickies that stuck out in my mind:

1) When I've autocrossed Mustangs in the past, I entered F-stock. Race tires are legal in F-stock and if you don't have em, other stock Mustangs and RWD cars are gonna spank your pants off!!

2) to the person that asked (a year ago) about autocrossing an S197... yeah, I hear you about the S197 being big and heavy. That's one thing I don't like about my '06 GT. But Shelby GTs do really well in F-stock, so it's not like you automatically rule out the S197 cars.

Of course you can move up to the 03-04 Cobra and have some very serious ponies with an absolutely modern rear axle setup. BUT, you are also talking some very serious money, and for the beginner all of that HP under your right foot is asking for trouble. It is too tempting for the beginner to come out of a corner before a long straight, nail the throttle and wonder why he ended up into the wall. With the supercharged Cobra’s you have a slight pause while the boost builds. When all of that HP hits the rear tires they break loose and you find yourself in a heap of trouble with little to no experience on how to overcome it.
"absolutely modern rear axle setup" sounds like great praise for this platform, although I've seen 03-04 **mach1s** and Shelby GTs log FTDs with their solid axles, so the solid axle is not as much of a handicap as people make it out to be.

Also, the supercharged cobras do NOT have a slight pause while the boost builds. It's quite the contrary! But I do agree that the TORQUE hits the tires hard...


I have no problem with anyone buying the new SN197 chassis and racing that. They are a great chassis, if not a little heavy, but we are talking about beginning to autocross and how to do it economically.
As previously noted, the Shelby GTs kick azz in autocross... so I'd recommend them as much for an experienced veteran as a beginner.

Again, I'll reiterate that in F-stock, you're hardly allowed any mods whatsoever. http://www.scca.com/documents/Solo_Rules/2010_scca_solo_rules.pdf

If you try to race your stang in F-mod, you're gonna be going against full blown racecars (unless your local autocross club is really small) and most people's street cars just have no business lining up against these guys... but even in F-stock, you're likely to be going against "stock" cars on slicks, so in my opinion, the best way for a beginner to be competitive is to pick a platform that is good in "stock" form (94-01 Cobra, 03-04 mach1, 05-GT) put some slicks on a spare set of factory rims, and practice practice practice!!!


Automatic versus stick, the stick is always preferable. I have an automatic and it has advantages. With the auto you can concentrate only on driving and braking, you don’t have to think about clutching/shifting, or missing a gear, the auto is a little better for a novice.
I don't think an automatic has any advantage in autocrossing whatsoever. Most Mustang's autos are so vague, it's nearly impossible to control the weight transfer because it's hard to know what gear you're gonna be in when you enter a corner. (unless you shift it manually). With a manual trans, you're almost always in second gear, unless your track is really long and straight (which they usually aren't) so it's not like shifting really affects your auto-x time very much.

You guys shoulda seen Kent Weaver's face when I powershifted first to second in my '99 GT when he did a ridealong as my instructor. He'd never seen anyone shift like that and he and his wife compete at a national level! (They've been featured in Tire Rack ads) But hey, that was just the drag racer in me trying to make it to turn 1 ASAP! :rollgrin:


For someone who is just starting out, I'd start by just trying out a few local Auto-X events to confirm that it's something you want to do for a while and spend some money on.

If it is, and you're looking for a few relatively inexpensive modifications, you can do some mild suspension modifications that will really wake the car up.
I agree with people trying it out to see if they like it. But I don't necessarily agree with making mods right away. I know F-mod is killer competition, but I think that even the mods you listed would at least put a car in street touring, which can be tougher competition than F-stock.



The first thing is better brakes on that car.
In my opinion, the first thing on any Mustang is TIRES, followed by a lot of seat time!


It should be noted that I'm talking about being competitive. If you don't mind getting smoked by anybody and everybody, then by all means, just go out there and have a good time. But in my opinion, if you're considering mounting any sort of challenge in scca solo 2, I think the best way is to keep your mustang stock, buy some good tires, and compete every time they hold an event.

Just my humble opinion... and although I've autocrossed, roadraced, and drag raced plenty of times over the years, I've not done any of it with any serious intent. So take my comments with a grain of salt.
