i broke my 7.5 with jsut street tires and bolt-ons. i have seen a 7.5 stand up to a 100 nitrous shot off the line and a 4000rpm drop while on slicks. the 7.5 is a very tempermental rear. if you feel lucky, get slicks, but it will last only a few passes. i seriously doubt you have the hp to push slicks though.
a set of nittos will be fine. just dont do any clutch drops or high rpms brake stalls and you should be fine
I just broke my t-lok using T/A 255-50-16R drag radials Friday night on my 7.5 rear end. Ran some good times up to then. Just part of the game with the lighter duty equipment. Will have my new one in Thursday.
