I want to get a set of 17x8.5 brock b1. the only offset i see at tunershop.com is 35. Is it possible to make this work. I looked on the fitment chart and the only offset i saw listed for 8.5 width was 16. What would i have to get the offset to, with the use of spacers, in order to make them fit. and id run a 215/40 tire, if that makes anydifference.

first, that's gonna be a stretch for your 215 width.
second, with 8.5" width, you'll definitely have to space the wheels out, and third, you might have problems clearing the fenders.
