Sticking to the question I'll say mid 12's. Ill say Gen 5 camaros 1/4 #'s don't really impress me bone stock . They do come alive with the right modifications and do belive , theirs fans waiting to put their hands to the z/28 for 1/4 mile purpose including myself. So forgive me if I missed the part about it being a circuit "lap" car . The z/28 is gonna draw a lot of interest once it's posted on YouTube punching lower 9 numbers saying ,hey circut guys ,look at what we did . This to me is kissing the "ghost". Make ur freaking hair stand up!!
Bowtie Til I Die!!
