Hi I'm looking to fit some wheel spacers to my st but I'm a little unsure what size to go for 15 or 20mm on the front as quite a few people are running 20's on the rear and 15's on the front! Is there a reason for this? My car has got the standard wheels and coilover suspension so can I get away with 20's all round. Cheers for any feed back

 

The reason most people fit spacers is because of brake upgrades and even then it's normally 15mm on standard alloys just to make sure it has clearance. 15mm front and 20mm rears should be fine either way though

 

Quick update, I fitted 20mm spacers all round with standard wheels and coil overs and have had no rubbing issues.
