RS05RR Setup
 

Was going to run some 17x8 Wheels but I like the RS05RR.

Thinking about RS05RR 18X8.5 +42 square with 245/35 michelin pss.

The car will be running around 250ish whp.

Any cons/concerns with that setup?

You may need spacers to get flush. ~+38/35 may be better offset.

15-20 offset. I run a =10 in my 17x8.25 xxr's

Setup should fit fine. No rubbing or hitting another. Depending on camber settings and such you can go with a lower offset as someone said if you want a more "flush" look.

Michilen dosent have a 245/35-17. If you want a oem height you need the 245/40. Which I have. @250 wheel youll have good traction. 375wheel is a different story. Lol

You will be fine, enjoy it, will be very fun

Do not go below +30-ish in offset, otherwise you royally screw up your handling, but changing the sign of the scrub radius.
