i was just thinking about a few things and came up with a few worries...
since the spring is what holds up the weight of the car, wouldnt the rear coilovers potentially cause a problem to the shock mount on the rear end housing? with the stock set up there is a big cup for the stock style springs on the back side and then the shock mount on the front of the housing, this i would think spreads out the stresses pushing down on the front/back of the housing. now with the coilover set up in the rear ALL the stress is put on that shock mount in front. can that mount take the stresses of autoX? everyday driving?
also another thing i noticed specifically with the Spohn rear coil overs (just the set im interested in), i have the Spohn Drag rear sway bar kit which is really thick and from pictures ive seen, it look as if the sway bar will interfere with my ride height adjustability, i want to lower my car as much as possible and it looks like the coil or adjuster peice would interfere with my sway bar. anyone have the rear kit and thick rear sway bar? is there room to lower it all the way?
thanks

 

my 24mm rear sway just barely clears. if it is an issue having them adjusted all the way down, you can switch to a 10" spring for clearance. as for the strength of the shock mount, i have no idea

a few issues concerning the front. you are limited to how much you can adjust camber and caster because of the spring going through the opening in the strut tower. just how much i dont know, i dont have a motor in the car to get it to a rack.

another complaint i have, but not spohns fault. ive got a pro fab kmember and a arms, and now with the fronts adjusted all the way down, the k member is resting on the control arm, and there isnt even a motor in the car. looks like i might be waiting for the spohn piece to come out
