Am sorry to say that I am in discussion with BC about the kit, as the coilovers are making thumping/cloncking sounds (is that correct Englisch?) on all 4 corners when driving on uneven pavement, over the last 2 months this is getting worse.
Ofcourse BC are quick to respond that there must be either a installation error made by me, or stabaliser rubbers/ endlinks must be worn/ making the noises.
I checked, and everything is tight, no play to be found in these parts and as before installing there were no noises with the OE parts, also not very likely.
As I wanted to make sure of myself, I had my race mechanic who is a highly experienced allround mechanic check things and he concluded the same: everything installed correctly and no worn rubbers/ endlinks parts and no play..
He performed a small by hand test of the coilovers on the car by lifting the wheels about 2" off the ground, having them hang free, put a breakerbar between the lift plate and underside of the tire and moved the bar up and down to see how the the wheel/ suspension would resist/ dampen the movement.
It turned out that he could quite easily make the wheel/coilover jump up and down about an inch without seeing the shock dampening this movement and without the car itself moving much.
He told me in his opinion this was strange/ unusual, the coilover should not be pressed in so easily and not move out without any visible resistance/ dampening by the shockabsorber.
He thinks something may be wrong with the short dampening capabilities of the shocks, possibly having the wheels jump on uneven pavement due to a lack of short dampening, thus causing the cloncking/thumping sounds.
At the moment BC seems to be closed for holidays,.... to be continued......, but I will not keep the coilovers on the car like this, the car now sounds like a very old car with worn suspension on uneven roads
