I had a set of H&R Non-dampening adjustable "Street Performance" coilovers on my 2008 Evo and it was crap.
The shock shaft had play and clunked everywhere after 3 months of steet driving. You could literally grab the shock with your hand with the wheel off and move it back and forth. They were solid brand new but wore out in 3 months!?
I thought it might be a fluke so I warrantied it... which took 1 month to process. Then the next set started doing the same thing after a couple of months... I warrantied it again and sold it. So much for German manufactured Bilstein shocks.
But who knows? Maybe the BMW shocks are better made.
