If you can hold on a week tops I will tell you.I have the same wheels (18x8 et45) and the same brake setup.I'm putting 12mm spacers on but that's more for looks than clearance.I will report back after the weekend if you don't mind waiting.
@mvb12 Merged the topics...
Info needed BUMP
You need a 3mm spacer, Alex at AKS can supply these and slightly longer bolts
