They are really firm and crashy, it doesnt even need a pot hole to make a big bang even a small dip in the road does it. I removed the springs on saturday and the fitment seems awful, they seem to stick out more than the cup of the shock, so you can see where the spring has compressed and hit the cup of the strut where the spring seats.
Ive put the standard ones back on for the time being, and i checked the struts are all ok. Some new 30mm springs should sort it, i would buy coilovers as i dont mind spending the money but IMO from experiance they're all to firm for road use.
Shame as i like the firm-ness of coilovers for track use
