Hey guys, I have a 3IS 250 Non-Fsport with the premium 18" wheels.

What is the biggest spacers I can run on the front and back without needing extended bolts?

Also, should I get hubcentric 60.1mm spacers to be safe?

Thanks guys.

 

On the 2IS, it is said that 10mm is MAX before borderline dangerous. Solid aluminum rings are a great idea!
