Can anyone confirm for me if the Kosei K1 racing rim needs to be run with a centering ring on an E36 car? I have a set of 15x7 K1s that are +38mm offset and 5x120 bolt pattern. I sold the car long ago but ended up with a spare set of rims in the attic. I am selling them now but the buyer wants to know if rings are needed and I cannot remember one way or the other.
Thanks,
Jeff
