Are those wheel adapter center locks? they look funny to me
Cool looking car.
When we couldn't get 19" tires for our rear wheels on the 935 we ran 16" all the way around. They were a WSC tire and as I recall they were 23.5 tall in front and 27 in the back. I know for sure we never ran the same height tire front and rear.
currently I am using 275/45/ZR16 in front and 335/35/ZR18 in rear just because there was nothing available. Avon was making proper sizes for the 935 in 16 & 19"so I was going to use those and have them grooved but heard Avon shut down
I would call Roger Kraus Racing and ask them what is the best application for your car and wheel sizes.
