hi,i have a 2wd saph cos with bilstein shocks.i need a set of springs which will make the arches sit just above the tyres.i have 17 inch rs 7 spoke diamond cut wheels with 215 45 17 tyres,the fronts are spaced out 3mm as its a 2wd and the calipers hit the wheels without them.i might have to go to 205 45 17s on the front as i think i will have rubbing issues,also the front arches are rolled.i was going to buy coilovers but theres other things i need before i buy them.like i say,i ideally want the tops of the tyres to sit just in or just below the top of the arch!cheers,lee
