Shouldnt do. All depends on the camber of the wheels. I also think with 0 deg camber 20mm spacers looked stupid. I have my camber to -1.15 or something now with 20mm spacers and they sit ok. 25 would have been better. I run H&R's because I wanted to make sure they were of good quality.
Id advise against coilovers as they need maintaining, ive also had mine on for nearing 2 years now and one of my struts is leaking, and i think the rear strut is buggered too. UK roads arent too kind IMO. Im sure others have had more luck. Can you pick up some fast road struts and springs??
