spacers bud, put proper ones, hubcentric... and not cheap crap from halford as they make the balance go mad at high speed where they dont sit properely on the hubs, i had a set of crap 10mm ones on the back of my s3 and at 100+ mph :busted_cop: it felt asif the rear wheels where trying to come off...(scared the **** out of me!) , they came straight off and in the bin and i bought some proper hubcentric ones.. worth spending the extra bit of money mate trust me i speak from experience lol
