Alignment was not an issue at all. Turns out I do have a little rubbing on the rear plastic fenders, mostly because I went 245 tire on 44 offset 8.5" wheels. They don't rub bad, but when you hit a huge bump they touch. I can clearance the plastic pretty easily I think.

 

Curious if it’s possible to keep stock JCW ride height with the KW coils? Unfortunately I have a fairly steep driveway and even at stock height I have to be very careful pulling in.

I’ve only had mine for a week now, but the FR shocks needs replaced and I can definitely agree with the unsettled feeling on the highway.

 

I have my front springs as high as i can staying in the KW recommended range and it is slightly less than 1" drop from my JCW sport suspension. So no, you can't keep it that high. I installed a M7 speed aluminum skid plate though to make sure I don't damage the engine/transmission. I've never rubbed on anything so far. I think I have decent clearance still.

The rear has more range. I have it about in the middle. Probably at around 1/2" drop and it no longer rubs even with 4 people on big bumps.
