Don't be surprised if the drag radials don't help. A friend of mine had a 1996 Mustang GT with bolt-ons. Those things are turds, he got a 14.6 out of it. His 60ft time wasn't very good so he hoped drag radials would help but they slowed him down. They did their job, but the car just didn't have enough power to break away with them sticking so good! Hah

And to back up that experience, my old stock Z28 had the same problem... but it had 2.73 gears.

 

The GT is a manual coupe.

 

The GT isn't a convertible, and it's a manual. I rode in it over to the staging lanes.

 

Gotcha. I watched the vid on my phone and thought I saw it was a vert. Makes it an even better kill then!
