Ford c springs
 
I've tried the search feature on this topic but never got the specific answer I needed. I'm want to get my '99 gt through the corners better but I don't want to lose anything from my 1/4. So my question is would c springs kill my 1/4 mile times? Also would these function ok with Monroe sensa trac shocks?

I know the best answer would be to get a coil over set up but that is a lot more than i want to spend.

These springs will be fine with your current shocks/struts. As far as it hurting your 1/4 mile times...I'm not too sure. I doubt they will have too much of an impact on your 1/4 mile times...

I will most likely go with these springs (soon :) ) as the drop is mild and the spring rates are much better than stock.

That's good to know because I just bought them. I'm really hoping to kill the wheel gap I have between the fenders and tires.

I just installed the c springs on mine, only took it on 1 test drive since, didn't seem to impact any type performance as far as I could see. it drops the front 1.5', and the back 7/8'.

72 Fastback that looks awesome. That is exactly what I'm looking for. Are you on 17 or 18 inch rims? Also how much did that KB blower set you back? I want to get one for mine it a few years.

Is this with or without the Spring Isolators? I about to pull the trigger on either the C or B FRPP springs. Debating on whether to put the Isolators on since it will reduce the overall drop....

I installed Ford Racing C's in some 6-7 years ago along with with KYB adjustable AGX's. Loved the improved handling. Time to replace the shocks and undecided as to what is going in next.

It has 17 inch rims with poly islolators on all four corners. I spent $6500 for the blower with a couple of dyno pulls and a kenne tune, and a few misc parts. It still has stock exhaust on it. Those pictures were from a dyno event. I closed the hood before they drove to the dyno and nobody knew it wasn't stock until it was on the dyno. lol!.

HAHA I'll bet you have a lot of fun messing with people who think you're stock. What did you end up putting down with that setup and what size blower was it?

$6500 is more than I paid for my car all together! Time to start pinching pennies.

That looks sweet with those bulletts tucked in right under the fender. Any idea how much lower not having the isolators would drop you?

C springs are stiff. They absolutely WILL hinder your quarter mile times, but they handle nicely.

I don't think even the guy driving the car to the dyno knew at first lol! When I had it on a dyno jet it made 358rwh 409rwt @10.8# boost. It made 303rwh 322rwt @10.2# boost. This was on a mustang dyno though.
The tuner said it should run high 12's as it sit at around 109mph. I don't know about the mph with stock exhaust I told him. The Afr average was 11.1 but would in the 10's at times. They said the tune was safe but could get another 30 to 40 horse out of it. The drum was loaded at over 3600 pounds. Maybe I will get a custom tune eventually. i think 340 horse on a mustang dyno on a bone stock gt would be awesome.

I would think another 1/2" anyway. IT has about 3/4" of rake on it or so right now. I make take the lower isolators off the rear control arms when I change out the shocks. Those are 9" bullets with 275/40/r 17 nittto all around.

tlmissig61 02-07-2014 03:11 PM

Sharad, would "b" springs work better as far as lowering and minimal impact on 1/4 times?
