I've just replaced my knackered suspension for a koni sport kit (-30mm) and have hit a problem.

The spring cups on the front shocks are rubbing on the tyres. The cars running 18" Rondell's with 225/40 R18 tyres.

Spoken to a couple of tuners and they suggest either using a hammer to alter the the cups so they fit (not a prob as the springs are tapered so there's loads of spare meat on the cups) or to use 5mm spacers. Not too happy about using spacers as there isn't much meat for the nuts as it is.

Any idea's????????
