lemme see if i can give you guys the low down on what i'm aiming for... my 90 gtu isn't gonna be a full time race car or anything, but i do want it to see its fair share of track/drift days. most of my driving however will be done on my local mountain roads so i am not lookin for a "so stiff its unsafe" set up. i've looked at various springs for a spring/shock setup but those don't seem stiff enough but i dont want to spend $1500 on teins or the like. i did read a thread on the stance coilovers which i saw earlier the price is at the higher end of my limit but still okay so i was thinkin about those but i still wanted to get yur guys' opinion. thanks, all!

 

There are no good, stiff drop in springs that don't drop the car far too low. The closest thing is the RSR Race springs, but they seem to always be on back order (lots of posts about it). For a stock type shock suspension, the only real, good solution is Ground Control coilover sleeves. Add those to your choice of adjustable shocks (the non-adjustable ones aren't stiff enough) and you'll be good to go. That's what most ITS racers use. For spring rates, 400/275 with the stock front bar, no rar bar, should give good balace. Don't lower it too much and you won't need to worry about getting camber plates and rear camber adjusters to correct the massive negative camber that will ensue (in the rear especially).

For a budget shock, the KYB AGX is a good choice, if you want a better shock, and are willing to spend a little more and modify the front struts, then the Koni Yellows are the way to go. They're the best stock type replacement shocks. Another option is some race valved Bisteins, available through ISC Racing, or Mazdaspeed (need to be a member, and race twice a year). The Bilsteins are a better shock, but aren't adjustable, and are much more harsh (worse ride) than the Konis. I've seen accelerometer data of the same car with both shocks, on the same rough road that confirms it.
