I didn't want to start a new thread, but wondering the same question for my silver C2S which needs a new suspension. The car is principally used for tracking and A/X (the two may be a bit at odds with each other), but I don't trailer the car and still need to be able to drive the car on the road to and from events (or the shop). Focus is on the new suspension and bushings.
Is this still the right list from Bill V below? Any other recommendations? My mechanic seems adept at track set ups, and had recommended 400 lb. front coils and 500 lb. rear coils.
Thanks, Jim
From Bill V:
"Here's the recipe for an extremely nice and capable dual purpose 993
Elephant sport bushes on both ends of the front A-arms
RS rear A-arms, & KT arms
new stock camber links
Tarett or Rennline toe links
MCS shocks 600/800 springs
RS sways
RS wheel carriers and think about solid rear sidemounts"

To follow up here since I'm the OP.
I now have the following and have been pretty happy so far. I drive in white/black groups. I had instructor come out with me and his comment was "very well set up car".
Here is what I have:
-9x18 and 11x18 wheels with 225/275 NT01s - this is the most noticable upgrade. Much stiffer sidewalls.
-RS sway bars (max stiff in front, middle in the rear). I'd like to losen front a bit and stiffen the rear further as car now understeers more than it used to when i had full soft rear and front.
-1.6 camber front -2.5 camber rear
- H&R street coil overs
- rear tarett tow links
- elephant lca sport bushings
- gt2 inner tie rods - more precise steering
- pagid yellows (getting girodisk for front)
Edit: gt3 seats and harnesses - best upgrade.
I wore out nt01s in 15 days because I ran pressures too low. I was running them in 25F tepms in april, which I'm sure didnt help. Gonna keep them at 35-37psi hot after cool down lap and see how it goes.

You have an additional issue w/ an S in that the rear will often have wider than a n/b wheel and tire and wider track in back, these induce additional understeer, to correct it the the rear shocks should probably be another 50-100# stiffer
I'd also use the Tarrett RSR inner toe arms, mono-ball shock mounts will help get the suspension where you want it though the rear will still be camber limited unless additional steps are taken.
on a tracked car aero is huge CS aero for that, for A/X the RS or stock is fine and you hvae even more of a desire to dial under steer out.
ride height is also huge but w/o RS wheel carriers you are limited to a bit under RoW M030 height

8.5/10 x18 wheels 235 or 245 front 275 or 285 rear tires
Lower the car as much as you are comfortable w/ if you get down ~RS height use RS wheel carriers and think about solid rear sidemounts
You can use mono-ball shock mounts w/o causing issues in street use, try to use sealed mono-ball bearings where possible
If LRP is visited a lot try to use non-directional tires so you can swap L/R tires

My car was driven by Craig Stanton, pro-driver, at Buttonwillow Raceway. When we came in he said there are only two things I can do to my car in the future:
1. Wash it,
2. Wax it.
This was the first time I had been a passenger in my car. What a memorable experience, Craig so smooth.
That's it. I have taken his advice, and if course always look to Bill Verburg and Steve Weiner. And one (1) more thing, re-gear the car.

Thanks for all the great replies. rrally helpful feedback. I should also mention that the car was modified by PO with an Uwe Gemballa suspension and has a lowering kit installed. She rides below RS height currently, shod with Fikse 18"x8" and 10". Here's a photo. Thanks again for any feedback, I'd like to get this right the first time.

I am having a real tough time...
...fostering up some empathy, two Carrera S cars? The pictured car is gorgeous. Seriously, there must be a good independent Porsche shop somewhere near you. I have been know to tow 4 hours to see my guy, each way, and worth it. Tell them what you want and ask them to set up the car accordingly.
You'll get some many different opinions on the Forum(s). Bill Verburg is right on the money, always, If your car is super lowered and you don't have front RS uprights, you need them.

I have done all of the above, except, my springs are 100 Lbs stiffer front & rear, and I don't have RS rear A arms. But I do have the full ERP rear linkage treatment.

the op asked for a compromise between street and some track, which is why I recommend the Elephant sport rubber front paired w/ RS rear, this sharpens the handling considerably over stock while retaining a great ride, A variation on this is to use stock toe arms for more of a street bias or mono-ball toe arms for more track bias. Changing all the bushes front and rear to mono- ***** and turnbuckle arms similarly further sharpens the handling. The turnbuckle arms prevent the migration of alignment settings that is often seen in the back due to the stock eccentrics moving.
wheels and tires are another area that can be used to sharpen handling, Ideally 9 & 11 x18 w/ 245/and 285/30 tires even larger w/ more power. Easier to fit compromise is 8.5 & 10 w/ 235 to 245 and 275 to 285 rears, shorter is always better for many reasons. bas 8 & 10 w/ 225/ 265 is a decent way too go too.

Thanks for all the great info in this thread.
Anyone know if there's a difference between the Elephant Sport bushings and the Rennline HD bushings? For the front control arm.
