I just got off the phone w/ a sales(woman) from Well's Performance and first she told me the 15" wheel wouldnt fit my 98 cobra because it hits the IRS. Ok so I told her it was a 98 and IRS started in 99. Then she tell me I'll still need a 16" wheel or I'll have to grind the "banjo fitting"? Something about grinding my brake calipers or somehting???? Im super confused and I know ppl are running 15" welds on these cars so did you have to do any mods to get them to fit????? please help i wanted to order these wheels today! thanks
