First off, I apologize for placing this in the FI forum... but I would like feedback specifically from guys that are turbocharged making high horsepower. I could not seem to find a lot of feedback in the Suspension forum with set-ups similar to mine.

I've been doing a bit of research on suspension set-up for our shop AP1 S2000. We are currently making 550rwhp/410tq at 19.5psi (pump gas). Once we upgrade our rear end differential to the Ford 8.8 rear-end we will be tuning for both e85 and q16 which should easily make 700rwhp. We finally received our 949 Racing 6ULR wheels (17x9 255/40/17 F & 17x10 315x35x17 R Nitto NT01) and it's time to order the suspension components so we can pull/roll the fenders for fitment. Yes it will fit... yes it will work... it's already been done on one of our client's set-up.

This car is more of a street application and it will probably never see a road course. Unfortunately we have only 1/8 mile tracks in Charleston, SC so it will not see the quarter mile track as often as I'd like it too due to travel and time constraints. So with that said, I would like a nice suspension set-up that will do very well on the street as well as on the 1/4 mile drag strip. It's not a daily driver but I would prefer a decent ride quality and not have it ride around like a civic with 1000# springs (we've done tons of these, lol).

Options (We have dealer accounts with both Skunk2 and KW so I'm simply listing MSRP pricing)

1) Skunk2 Pro-C - We can set-up our own custom spring rates but I cannot seem to find enough feed-back on this set-up. MSRP $1,646.69

2) KW V3's - 515# spring rating. With the amount of tire we have, I have been told that the suspension wont be at 100% of its potential. The spring rates and valving on nearly every suspension is designed with stock to a mild amount over stock tire size in mind. Set-up more for comfort. MSRP $2,399.99

3) KW ClubSports - 570# spring rating. Come with top hats and the spring rates and valving is setup for more grip vs comfort. MSRP $3,199.99

Thanks for the feedback. I'm open to other options as well

 

Strange makes a great product... we ran them on our EK K series drag car a few years back. PM on the way

 

I've been trying to do some research on s2000 drag suspensions also, I think i am going to try 12k and 14k rear spring rates at first

 

Does anybody else have any feed back? I'm getting zero help over in the suspension forum.

 

im using skunk2 Pro C coilovers,i was making in the 650-700whp area, the car is down now being built , but i was just driving it on the street, didnt do any launching or tracks runs, but as far as street buisness i love em.

p.s- i had volk ce28n's 17x9+35 w/ 255/40/17 hankook ventus rs3's all around with rolled/pulled/flared fenders

 

It's more about WHAT tires you'll be running than anything else.

Sounds like a street/drag car. If it's full drag I'd really consider serious suspension changes but essentially linear travel is what you're needing for drag launches to work best given we don't have much suspension to start with. I'd look into what valving is the least progressive of the three so that it's able to blow through the suspension and stay squatted on launch. This is assuming you keep the setup the car comes with from the factory and just change coil-overs. Rebound of course you'll want to be very slow so research what would allow you to give a lot of adjustment there too, in-fact that might be more important even.
