I'm looking to put some 17" FR500's on my 99 cobra but someone told me that some modification would have to be done to the irs to get the rear ones mounted. anyone know anything about that?
Intested in this same question - Will I need to modify the IRS bolt to fit these tires with 285/40/17 Goodyear Eagle F1 GS-D3 tires in the back? http://www.americanmuscle.com/anthracite-fr500-wheel-17x9.html
