Re: Cutting my GTA stock springs? help..

with the relative cheapness of aftermarket drop springs, such as those from summit, id suggest replacing them rather than cutting. Besides, its hard to cut each one identically, and you will have uneven ride height, resulting in alignment angle changes. hopefully you were going to align this anyway

Re: Cutting my GTA stock springs? help..

cut them, the drop springs are pretty crappy too, my eibach 2' drop springs didn't drop worth a crap, I cut the stock coils on my 82 trans am, much cheaper and much better results

cut half a coil for starters

Re: Cutting my GTA stock springs? help..

The rears you have to cut from the top side, the bottom end has a pigtail (its smaller) and you need that on there. The fronts... take your pick. I'd start with a half a coil up front, the rear you can take more off but may not hurt to start small because those are really easy to R+R to get exactly the height you want.

Re: Cutting my GTA stock springs? help..

i think the front springs are ground flat on the top, so you would want to cut the bottom of those springs.

Re: Cutting my GTA stock springs? help..

When I cut some WS6 springs for an RS years ago, I did 1/2 coil up front, 3/4 coil rear/ The result was pretty good, bu I also wish it had been a little lower.3/4 front, 1 coil rear might have been good, but you certainly can't go backwards.

And I set my coils in a bucket of water with only the tops sticking out, to dissipate the heat. Was it REALLY needed? Maybe. But certainly can't hurt either. And I used a 4" grinder to cut mine, with a 1/4" thick grinder wheel. If I have had a 1/8" wheel, I woulda tried that, but then you gotta make sure you cut STRAIGHT & not flex the disc. It would really suck to have a 3000rpm disc come apart & the flying shrapnel find you!

Re: Cutting my GTA stock springs? help..

If you want the car level, got a bit more in the rear. If you want it is sit like stock, higher in the rear, cut the same amount.

R&R usually means Remove & Replace. Where'd you see R&R?

Re: Cutting my GTA stock springs? help..

That was in my post.

I havent seen a stock front spring with a ground flat end, IIRC. I've seen aftermarket ones made that way though.

Re: Cutting my GTA stock springs? help..

As Pablo said, no plasma or cutting torch, too much heat. Best to use an abrasive type cutter. Dean
