ok guys. help me out on this one. i got a 94 LS. i just ordered some 15's with 42mm offset(which i have no idea wat da hell that means) but anyhow, i want to order either baer or wilwood front brake kits. will it fit? AEM and Brembo brake kits require that u have 17's right? i was wondering if i'll have enough clearance with 42mm 15's. thanks guys!
