I recently installed a set of (puts nomex flame suit on) JIC C/Os on my 01 996TT. I also installed a H&R 24mm rear sway bar at the same time. My prior suspension setup was stock with H&R springs. Needless to say I am very happy with the setup.

I set the rear ride height to 25" (L/R) and the front to 25 3/8" P & 25 1/2" D. The added 1/8" on the drivers side was placed to offset the drivers weight. I placed some weights inside the car, 185lbs, to mimic my weight. The car sits flat at 25 3/8" with this measure in place.

BTW - The stock setup with H&R springs sat at 25 1/8" (L/R) rear & 25 7/8" (L/R) front.

My question is, it seems as though the front of the car wants a bit more height than the rear so the car can squat forward and soak up braking in the front under heavy load. Does this height seem to be something that is consistent with others who do aggressive street driving to moderate track driving?

(falme suit still on) Also, I took the car for a spirited drive over the last few evenings at a local haunt with some good curves and with the sway bar on the light setting the car stayed flat and controlled with minimal body roll.

I am very happy with the setup and would recommend it, bang for buck, to anyone. I do not have the upgraded sway bar links in the rear and plan on buying the soild ones soon.

Constructive feedback wanted.

 

I didnt set my coilovers up as neither did most of the people here but more height in the front does not sound like a good idea.

The best idea is a good corner balance after you've found your optimal ride height.

 

Thanks, corner balance is next.

I have a set of Long Acre scales an alignment bar and a hub camber/caster tool. I like to wait a minimum of 1 week before dialing in the alignment and corner balance because, in my experience, the springs tend to settle a little in the first week to week and a half.

I crewed for a GT2 team for 6 years learned a few trackside tricks during that time........

 

yes, generally you do want a little rake in the rear. The rear should sit just a tad higher than the front. Having the car corner balanced is a must do, but they will make minor adjustments on your ride height at that time.

I have an evil driveway....can I get JIC's to be stock height "exactly"...will eventually fix the driveway...but it is cement and a fix is not cheap....


TIA

 

When you get your alignment, do it to GT2 specs. Car will handle amazing. That is what I did with mine - http://www.vividracing.com/forums/me...sche-cars.html

 

Thanks for the feedback......I will dial what I can myself and take it to a local Porsche shop if I am not happy with the results.
