I will listen for the system to activate...maybe it's not......like I said both BMW and the independent shop looked at it for issues and neither found any?? It sits the same height running or if its off even when it's off for a few hours I measured it and it was the same height. I might try to crank the H&R links up as high as I can tomorrow and try hopping on the rear a few times and see if I hear any thing happening. The independent shop has contacted H&R 2x now they don't seem like they want to do anything at this point
I thought they would have better customer service...I have ran their springs on a few other cars in the past and had good results. If KW would sell just the font coil overs I would get a set but it seems like my rear is the issue....maybe I will jack the front up a couple inches and see if the rear tries to level it out, I guess then I would know if the low the front is keeping the rear from coming up.
Skunk our over all diameters are still almost the same. Front is 0.3" difference and the rear is 0.1" difference so negligible differences. I am jealous of your wheels though they look great.
