Good find. So get 1999 M3 front bump stops, and shave off the rear stock guide supports by .3"? Can you do an exact measurement since the shop wouldn't have the "modified" dinan bump stop?
Any idea how much it would cost to install/reinstall these 4 things?
I have H&R springs, think this will be an upgrade/improvement in performance/comfort?
