Whenever I have asked what springs, struts, sway bars, misc. suspension parts to use, I frequently get mix and match the components since no one kit has it all. The application is road course racing, club racing time trials, and autocrossing, NOT drag racing, that requires a different setup, imo.

Could some one please list a set of suspension parts that will work good together and achieve 1G with the proper tires? I am partial to the Tokico D-specs. I am looking to spend $2k - $2.5k. For instance the FRPP leaves out the panhard bar. The Roush kit doesn't use adjustible shocks, neither does the Steeda, although Steeda's kit comes close to what I want, as does the BMR.

Links to manu. sites and vendors sites would be good also.

Thanks in advance.

 

Define proper tires? Standard street tires, something like Azenis 615s or are we talking R-compounds? Do you still want to be able to drive it on the streets without weekly trips to the dentist?

 

Both: Kumho V710s on the track and Potenza RE-01R on the street.
Adjustable so that you can drive decently down the interstate at 90.
One set of RR tracks between me and the interstate.

 

Here is an ideal for parts needed not comment on supplier

I don't know why your goal is G's. It's a pointless measurement. If you are serious about perfromance, compare lap times. Hell, I bet I can get close to 1G with the proper set of R-compounds in my stock suspensioned GT.

 

I guess what I am looking for then is the best road racing suspension setup for $2k. The stock GT runs about .88g around a track, I want better than that.

 

You may need to study up on race car suspensions to understand what contributes to superior handling and what particular changes give you the most bang for your buck. Start incrementially, make some choices and then experiment on your own.

To the extent I have pushed mine, in stock trim the car is very well balanced. The shock settings suck, so the Spec D's to me is a good starting point, but that won't necessarily means the car with corner any better on a flat smooth surface. Wheels / Tires aside, additional roll resistance is good, so a balanced sway bar set up is another good increment. Lowering might come next, but that affects several other things you need to correct to gain the full benefit. a) firmer springs b) adjustable panhard bar to correct rear axle position c) lower front ball joint (steeda) to correct front roll center shift penality caused by lowering d) BMR LCA and UCA relocation brackets to restore and improve rear suspension instant center e) adjustable LCA / UCA (with poly bushings) to correct pinion angle (as a result of lowering) f) a good alignment. Determining best tire pressures helps too. Access to a skid pad would be very helpful in doing your final tuning.

I am not sure anyone has packaged the 1 G kit yet, but with study, experimentation, and patience you could get there.

 

IMO the FRPP and Roush kits are much better than stock and will get you pretty close to your goal. I would guess the Steeda kit is also very good.

Roush says - "With KD tires, Stage 2 will generate over 1.0 g in lateral acceleration."

If you want adjustable shocks, get the springs and sways bars from one of these kits and add D-Specs.

 

I'd also check into these.

If your going to run it hard, the extra 1 degree camber adjustment you can get with these could pay for itself in reduced front tire wear. Most R-compounds like more negative camber than you going to get with the stock upper mounts.

 

I just installed those, nice quality pieces and very easy to adjust
