I am sure this is probably elsewhere in the forum but the search is down and it's go-time for me to get the odds and ends I need.

My question is, is it at all possible to run 6" springs on all 4 corners of the car in typical STR trim?

TheNick has indicated that this probably isn't a problem on the front.

Has anyone done this in the rear? This would be assuming the following:
-Target ride height of ~.75 - 1" lower than stock
-added length of helper springs+spring spacer between helper and regular springs
-OEM top hats modified to fit Koni's


(I have access to cheap used Eibach springs in a variety of rates between 600# and 750#, I might buy them all if they can be swapped around on both the front and rear of the car)

 

I see no reason why you couldn't use 6" springs.

 

The only concern with shorter springs is less available travel before coil bind. It's probably doable, you'd want to confirm by measuring your available shock travel.

Spring length is also going to be dependent on what ride height you want and the amount of threads you have on your adjustable perch setup. It's possible that even with helpers and helper isolators and a 6" spring your car will end up a bit lower than you want even with the perch as high as it can go. Doubtful, IMO, but something to consider/measure. IIRC, I had my front perches pretty close to the top of the threads with 7" springs, helpers and helper isolators when I had the big springs installed.

 

Then is there any reason not to run longer springs, say 8, 9, or 10 inches, if there is enough room? What is the advantage of a shorter spring and helper, vs same length main spring, and same ride height?

 

Myself and Sal Dipompo (exhaust_note) are officially registered with my car for the NEDIV divisionals in DC at the end of May, Lets see how we do.

 

I already won

 

When I ran a spring that was too long on my WRX's coilovers, I had a problem with the spring, 8" Hypercoils at 450 and 550 lb/in, bowing in and rubbing the coilover threads under compression/decompression on the road.

 

we'll see about that skippy...

 

I'm new to setting up a S2000 and after following this thread for months I have a question. I've noticed that Skunk2 does a adjustable monotube shock with separate ride height and spring preload adjustments. It would seem to be real advantage to have a ride height adjustment after setting your spring preloads my previous experience is that any spring perch adjustment to a front corner effects the opposite rear corner and so on. Has anyone tried these shocks or are they complete junk?In the past,I spent considerable time corner weighting my Lotus Elan and that separate ride height would have simplified this procedure.Any thoughts on this subject?

 

I would not do it. Koni or better, imho.
