What are good offsets for a Type R? Like would a +35 be bad? Also is a 15 or 16x120mm same as a 15 or 16/114.3? Thanks

 

35 will work, but is more on the aggressive side - we use this for track use with proper camber adjustments. I would not recommend for a pure street car.
Most street apps are going to range from 40-43mm (Volks for example).

5-120 is BMW fitment.
