STR Prep - Shock / Damper and Springs Discussion SCCA Autocross STR Class

I'll add that if I had your KW Clubsports, I'd run OEM top hats, 750/650 rates, whiteline front sway, and and ap2 stock rear sway. No lower than 13.25 ride height. (For travel's sake in the rear). Think I'd be real happy.

I keep watching good drivers beat each other back and forth - KWV3's takes win, then AST 4150's, then Ohlins, and round and round it goes. Had thought about the AST's and all their monotube glory, but the KW's kept giving them a run for their money, without the frequent rebuilds. Will be interesting to see your thoughts after running them for a while. Best comparison would be on equal spring rate, but seldom do people change shocks without changing rate a bit, so a direct comparison might be hard. The biggest selling point to me on the KW's was the fact that compression change was LOW SPEED, where it matters most in affecting handling. Even many expensive shocks (including MCS double adjustables) were still changing high speed compression instead of low speed. But if you daily drive your car, or if you race on smooth and then bumpy lots, I suppose even changing high speed compression could have advantages for you. But if you don't daily it, or don't encounter very bumpy lots ... Conversion to double adjustable, if it's only high speed compression, might not be worth it. I don't know. Just something the think about. You have to spend huge money to adjust low speed compression on most high end monotubes, which I can do with $1300 used KW's. Low speed compression is very important in autocross. Doesn't have to be adjustable per se' if you can get the car to do what you want with rebound adjustments, but you want to be present in high doses, lol. That said, there seems to be camps that run also low compression ... But it seems more national winners are in the more low-speed compression, more better camp

ViperASR really liked the 13k/11k Swift springs that went with them and recommended the same rate on the AST's for me(they have 650/550 currently) Its going to be a lot of changes at once though as I having been running "stock" this season. And will be going completely square at the same time(got oem ap2 wheels with 245F and 255R now)
Maxcy just got back to me and said its gonna be about 1500 to convert to doubles.....not sure I need that, but after having it with KWs I feel like I want it even though once I set the compression/bump, I never messed with it again

I would run 6 inch front and rear springs with those rates.

I am planning to use GC sleeves and OEM top hats. The Konis I have once belonged to TheNick actually. I bought the car from a guy who got those Konis from him.
As far as helpers, I am not sure yet if I will be using them. I would like to avoid needing them if I can.
I have not heard yet about the issues of contacting the A-ARms. Is that happening mainly when running the 2.5 inch diameter spring? GC sleeve kits only come with 2.5 inch springs, and even if I go with Hyperco springs and some other sleeves 2.5" does give a bit more flexibility in finding springs and I believe is a bit cheaper.
Thanks for the replies so far guys.

I am likely going with 2.25 inch springs now, since I may not be re-using the old sleeves and will be replacing them and the perches. Aka, not using the GC sleeves and perches.
Still trying to get a better idea for the springs, but likely will be going with 8" and 7" or just 7" all around. I think that will keep me in a spot with some adjustability on the sleeves with the ride heights I am choosing, but I am still playing around with those numbers.
