Don't get me wrong ... I'm not havin' any ride issue whatsoever in term of stiffness, I installed the springs for over a year and been happy (maybe unlike the others) it's tighter since an upgraded spring rate that's a given condition BUT about the bumpstops is a diff. story, the issue is if the car ridding on a rubber you can imagine that the bounce will be in a wrong rate since there will be no suspension travel during compression and the rubber will add more bounce to the higher spring rate so you may get additional stiffness from the rubber.

Plus the amount of drop will be will be all wrong since instead of the body sittin' on the spring (on stand still) it'll be sittin' on the rubber bumpstops it'll be the same as you put the car like on a wooden block so it's not on a jack but it's being supported by somethin' else ... like DrLev99 experienced when he posted his finding and the height/drop changed due to the bumpstops.

Anyway GL!

 

Regardless of how the car rides, it will look so much better!

That said, don't drive it...just stare at it, take pictures of it and post them on this forum.
