just curious, i never took a measurement of my ride height before i put the box in. i wanna see how much if any, its dropped since i put it in.

someone that has afactory height r53 (mine is an 04 JCW if that makes a difference, but i dont think i have the actual JCW suspension...just normal S suspension) and you are on 215/35/18 tires, can you measure the front and back from the floor to where the arch starts in the center of the wheel well?

i would like to see if mine has changed any in the rear yet (no batteries or subs in yet though)

 

I had thought that regardless of wheel size (not including bigger than 20's) that actual tire height remained unchanged. The rim gets bigger but the tire height gets smaller equaling out and allowing for stock ride height. I would suspect that aftermarket springs would have a more desirable lowering effect that you are looking for.

 

depends..some people run 205/40/17, 215/45/17, 215/35/18, 215/40/18..all different heights..overall they are similar but id like a measurement from someone running the same size tires as me
