What is the fastest 05 on street radials?

Just wondering. There is a local guy that is running 12.90 at 108mph on street radials tires. I believe this is the fastest 05 Mustang GT in the country on street tires and bolt-ons. I'm not a fan of the 05 but his car is pretty nice. :nice:
 
They should be able to match a 99-01 cobra with stock heads/cams but all other bolons.The 05 hooks so well stock I dont expect slicks to make a HUGE difference. I say he will pull a good 12.20 at best.And he can say bye bye to that rear end if its stock.
 
I already busted the diff in my car. The diff casing spread/cracked. The spider gear pin was spinning and has a groove in it. It was about to sheer off, had I made another run on it. The locking pin that keeps the spider pin from spinning was bent. The spider gears were worn bad as well. I've gone to a auburn pro diff and changed from 4.10's to 4.30's. I'm just waiting for dyno time and a custom tune.
