Ok so I wanted to get the stance of my car right. So I ordered a set of BMR springs (SP001R from Summit) and a full set of Koni srt.t shocks. Just finished the install. I ground down the spring perch to fit inside of the front lower cups like I saw on here to do. Everything went together ok. But now the stance is jacked.

Front:
Before- 27 3/4"
After - 27 1/2"
Part number on spring: BMR-SP002RC





Rear:
Before- 28 1/2"
After- 26 1/2"
Part number on spring: BMR-SP003RD




All measurements from the ground to the top of the wheel wheel lip.

So the front is only 1/4" lower than stock and the rear is now 2" lower.

Any ideas? I've been searching on here but haven't really came up with anything.

I run that exact setup. Both my front and rear are roughly 26.5". Stock was 27.5" front and 27.75" rear. You didn't run a spacer up front or anything correct?

Just the piece that goes in the lower spring cup. And I ground it down so it fit properly.

Still not sure why the back dropped 2" though. I did put the rubber mount on top of the rear springs before putting them in place.

I tried calling BMR but missed them by 3 minutes.

Yeah from my understanding it should be roughly a 1.2" drop regardless of the starting point. In the rear i put the isolator up top as well, so that shouldn't be the issue. I have no clue lol

I added some pictures, maybe that might help show what I may have done wrong. I am out of ideas.

Went back out to the garage and now the front is at 27". Do the springs just need to settle maybe?

Yes they do need to settle briefly. I know mine did. I'd go take it for a quick spin and see if it settles a tad more

Here's after a drive. Rear still seems a touch lower than the front.

That looks pretty close to mine

Looks about the same as mine. Mine seems slightly lower at the rear but very close.

Thanks guys, makes me feel better about it. I think it will be ok.

Looks about right to me and love the Hardtop SS!

Yeah definitely drive it. Mine settled right away after driving it.

Any issues with bump stops hitting in rear?

dudesqueak

There is some kind of noise in the rear when I go over big bumps that I haven't figured out yet. I can't decide if it's just because I got the stiffer BMR springs or maybe it is hitting the bump stops. How can you tell if the car is hitting the bump stops?

You might look under there just to see how much clearance between the bump stop and axle, when I put my rear springs in this was the "clearance" BEFORE and AFTER I took out the stock SLP aluminum space that was under mine, even with this lil clearance they hit so I went back to stock rear springs until I can get my Konis in, if that helps, but I tend to travel with like an ice chest, small ezup and folding chairs in my trunk for cruise inns and such the few times a year I use my car plus two people so that is why I went back to stock springs in the rear...BUT I rather the bump stop hit than the tire hitting the fender, IMHO

Thanks, I like it too. My '94 Z28 was a T-Top car and I honestly don't miss them.

Thanks for the photos, I will definitely take a look. I just put new bump stops on it before putting the springs/shocks on it.

Loosening the bushings one at a time, rocking the car, then tightening them back up helps the springs settle faster, and that's advice coming straight from Eric Kent at BMR when I was talking to him about settling springs. Here's exactly what he told me.

"They should be settled in 3-500 miles. If you still have rubber bushings, you can settle them quicker by loosening then re-tightening all the control arm bushings one at a time and bouncing the car some while each is loose. If you have poly or rod ends, you wont have to do this and the car will settle sooner"

My stops had about the same amount of clearance as your last photo and I'm running over 3x your spring rate. They still hit the bumps stops. Problem is solved now though

Thanks for the info. It's looking even better today.
