Anyone fitted 15mm spacers on the front (standard 18 inch alloys, eibach sportlines)
have 10mm universal ones on at the min but want better ones and might go a bit wider if it causes no issues.
I used to have 8J ET40 wheels (equivalent to a 17.5 mm spacer) and that was level with the outer edge of the front arch. Never any issues with rubbing, but that was on standard suspension.
