I can't answer your question but I can say that I've got TEIN SS coilovers that are stiff as a board and very low. I've had cops look round my car (not defect ones (whatever they're called)) and never mentioned anything about its 'lowness' lol

Only thing I've been pulled up on was when I had red indicators but now they are orange and blink like a mother.

But really, can they tell how far it travels without taking off the wheels?
