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
