track setup

  1. 18 in R comps for the track?

    E60 M5 and E61 M5 Touring Discussion
    I'm looking for a good track wheel setup for my 2006 E60 M5. Right now I have been running 19 in Nitto NT-05 tires on my stock M5 wheels. The trouble I'm having is R comp tires only come in 18in. My ideal setup would be a 275/18 front and a 305/18 rear. Do you have any suggestions?
