BMR SP088 drag spring lower amount?

[engineermike]

Has anyone measured the exact amount of lowering you get from the SP088 rear springs?

Is that spring for non magneride cars? I installed BMR rear drag springs in my Bullitt and retained the factory fronts (magneride car).

I was worried about the drop, so I I stalled Steeda 1/4” spring spacers to make sure I didn’t encounter any clearance issues.

I do know of a guy with a non magneride GT that has front/rear BMR drag springs installed. He told me that he was experiencing rubbing with them and was looking to change them out.

Yes, non magnaride drag “minimal lowering” springs.

Are you trying to avoid lowering your car, but want the performance of a drag spring? If so, I would consider adding the spring spacers to keep you at the same ride height. The spring spacers are said to provide double the height of any size that you order when installed over the springs.

In my case, I didn’t want to go any lower than a 1/4 “ from the factory ride height with the BMR springs, so I ordered 1/4” spacers to raise the ride height back up 1/2”.

I have a Whipple plus the mach1 HP fender trim so the front looks lower than the rear. I’d like .5-.75 lower in the rear and I think it would match better.

Here is the issue. This is all stock PP1 springs.

Oh okay, I see what you mean. That’s a big gap in the rear. Lowering 1/2-3/4 will be perfect. I think you’ll be good with those springs.
