holy moly guys, 245 will absolutely rub with these wheels if you do not have camber plates. at least slap on the dinan plates to get something. 245/40 i agree is too tall. you have to get a 35 series tire. Thats the only reason I went to 255/35 because most dont sell a 245/35. hankooks run fairly narrow, you will probly get away with a 245/35 at 2 degrees or less. I have seen 245's on at 1.5 degrees camber at an autocross. The boston autocross group has a lot of experience with this wheel, if you have any questions, drop by the new england section and we would be glad to help.
