Track suspension

Planning my suspension build and looking for recommendations from those that run their cars on Road course. What do you run, what do you like about it, what would you change?

I plan to run my car on track 5 or 6 times a year and cars is an occasional driver on street. I am okay with a firm ride but nothing race car stiff. I don't want to spend $3k plus on CO. Height adjustability would be nice. I am planning a watts link, LCAs, camber/caster plates, adjustable sway bars.
I will do all these mods at once.

I have talked to a few shops and had the following recommendations for COs, springs/strut/shocks

ST XTA COs. Seem a bit soft and I can't find any reviews for them on track. Like the price and they come with cc plates.

H and R race springs and Koni yellows. not expensive and one way adjustable. Have read that Konis quality/longevity is inconsistent.

Vorshlag/Bilstein track pro CO. Stiffer spring rates, good reviews, but expensive and non adjustable shocks.

Decisions, decisions...

Search for squidd's post on suspension options, he outlines a few complete set-ups. Also there is a post by csamsh with a summary run down.

I have to search for them too . . . maybe later when I have more time . . . "advanced search" might help, allows you to filter on username

I prefer quality over features in everything I buy for cars. Therefore, my obvious choice is Vorshlag trackpro.

I found it. neither was a thread starter, but both sqidd and csamsh posted good info in the thread

csamash - I agree, you get what you pay for! I am leaning towards the Vorshlag set up. It is expensive as it is not a mass produced. They were great on the phone. I want a proven set up that works and has some adjustment for balance (sway bars and watts link). The last 5 years I raced, class had a shock rule and we could not use adjustable shocks. We played with springs, sways, watts link and rear CA angles. I dont plan on making many changes, but I want to be able to get the car sorted out.

Yes you absolutely get what you pay for. I know this thread is about suspension but make sure you have the right brakes pads and fluid and consider brake duct cooling and SS lines.

I have done an awful lot of suspension work on my car. I don't have the high end coil overs or Bilstein shocks yet but hopefully in the future I can step up. I am happy with what I have and I probably would not notice much difference yet because I don't have a lot of road course experience yet.

If I was going to do it over again with caster camber plates I would choose Vorshlag. They are really not much more than what I ended up doing with Maximum motorsports caster camber plates and GT500 upper mounts and 05-10 struts. Most of my modifications are in my signature except for BMR rear handling Springs, Eibach prokit bump stops, BMR Watts link, Vorshlag SS brake lines and Vorshlag 3" brake duct kit.

PMDmustnag13, I have picked up a set up of Baer GT 14" 2 piston brakes w/SS lines that were used for only 500miles for half price ($650US). They are the Corvette C5 brakes. I dont know what pads are included with them, but upgrade the pads to a track use pad, have not researched that yet. I have looked at the Vorshlag rear GT500 upgrade and am considering that. Same with ducting, Vorshalg has the backing plates. I have a ton of used 3" ducting hose from my past race cars.

I like Vorshlag too but this is one area that you can get the exact thing elsewhere for quite a bit less money. Find an OEM repair parts website and search for the GT500 brackets there then pick up the correct rotors of your choice. I think prices have gone up a bit but I did mine for about $275. All you need are the brackets and rotors. Shipping from Vorshlag can get expensive too.

Let me suggest doing otherwise. You don't yet know what you'll really need when you start picking up the pace.

8 years or so ago I was where you are now, had a whole list of mods in mind for my '08 GT. Then I stopped and thought about it a bit and basically just drove the car. Then I got shocks & struts, some camber adjustability, adjustable sta-bars (and better endlinks while I was at it). But the biggie was better and wider tires on wider wheels. Later on, I did rear LCAs after being informed at a service visit that the OE LCA bushings were on their way out (poly/nonmetallic spherical, FWIW).

Then the track bug bit, the tires eventually got better and wider again, as did the wheels. Now I need more roll stiffness, and I've known for a while that I need more spring (nose dive under braking). But since a spring change is likely to drive a change in sta-bar adjustment and possibly a different rear bar, it hadn't been worth doing until now. Basically, observe before you try to solve.

But anyway, here's what shocks, struts, -2°camber, and 285/35-18 MPSS tires on 11" wide wheels can do for you out on the track (Aim Solo datalogging) with what's really only minimal suspension work. I'm not crediting the LCAs for much except that they probably make the hard driving easier to do comfortably and with more composure. Instructors love composure . . .





FWIW, the Koni problem seems to revolve around excessive lowering - and/or possibly overloading the trunk, which drives the rear of the car down as if it was lowered and still on soft springs. They should have enough damping for the H&R rates, just probably not adequate compression travel.

I am not familiar with the Baer GT brakes you mention. I assume they will fit your car without serious modification.

Not sure you would need to upgrade back brakes to begin with. Most of the braking is done by the front in my opinion.

I just installed my Vorshlag backing plates and removed the Carbotech XP-12 compound track pads and installed Carbotech 1521 street compound on centric rotors. The track pads don't have much left. Maybe 2 to 3 mm before the wear groove disappears. I probably wore them out on the street since I only did 2 or 3 track days on them and still learning. New pads had 9 mm thick pads and no wear grooves. I plan to install the front inlet plates and ducting this weekend.

I am sticking to Carbotech compounds. You can use the same rotors with different carbotech compounds. Carbotech Performance Brakes

I have a friend that is going to experiment with the Raybestos compounds. ST45 or ST47 compounds. Apparently Nascar uses ST47. Raybestos Racing Pads - Raybestos Brakes

Yes the Baer GT is a mustang kit

I need to google the pads part #s to figure out what they are. Part number starts with PBR.

Anyone tried H&R race springs with the Bilstein HD dampers?

That give some decent spring rate with great, reliable dampers.

If you haven't installed those baers, return them and get brembos for less money
