Yeah that 323 is actually right on par with where my car is at. My best street pass to date was 13.90 at some odd 102-3ish I had finally gotten a 2.29 60' though LOL My best pass to date was 13.53 at 101.5 with some TINY 20" slicks on 13" steelies with a toolkit in the trunk and the wife riding shotgun... That was at silver dollar and they didn't say anything about helmets... so Ryan I think you could throw the kit on and run low 11's and they probably wouldn't say anything about the cage lol.
