First off, I have a 69 Camaro so question pertains to it, not much reply on Camaro Tech. I plan on mini tubbing my Camaro but keeping my 12 bolt (not cutting to shorter length) so question is how wide/big tire can I go. the rims will be 15x12 Weld Pro Star. Has cal-tracs and shocks will be what I have which are comp engineering drag that have the 3 settings if that matters anyway. Thanks!
