Not sure how the 10js would be on the e30 m3 arches. I know another very helpful chap on here (Kelson) has a gorgeous b6 3.5s which most of us drool over and he has the 8.5j front 9.5j rears fitted which I think he says are just about ok...incase you havent seen it take a look here and froth at the mouth like me...ImysE30 wrote:It was the E28 one's that I was thinking of, they came in 8J and 10J
