I short shifted the 2 to 3 shift a bit for the video pass. The 27 inch tall Mickey Thompson ET street drag radial rear tires with 3.73 rear end and TKO 600 has been awesome in every way street and strip. That video sounds a little doggy going into 3rd gear I know. I was actually trapping higher speeds before getting the jets large enough to were the engine wouldn't stumble up top in 3rd and 4th. I'm pretty certain the car would trap 132 mph with sea level air with an average pass and run a mid 10 on easy start. Then again if you back the air all the way down to -2000 ft like that C6 Z06 dudes pass that everyone talks about I'd calculate out to about 9.99 over 140 mph. LOL
I recently put on a set of 17 inch wheels with Yokohama A032R soft compound. The rear 315/35 17s are about an inch and a half shorter than the 325/50 15 drag radials. Those 17s are a blast and pull like a mother up in 3rd and 4th. The 1,2,3 and 4 shifts are real nice and fun too. The problem is you can't get them to stick below about 50 or 60 mph. They hook ok once in 3rd, but you need to be real careful you're going in a straight line and don't hit any little bumps to loose control if full throttle. The 15 inch drag radials are much more forgiving and stick once heated very well.
The Mickey Thompson 27 inch tall tires with 3.73 rear are about 145 mph top of 4th gear.
The Yokohama 25.5 inch tall tires are about 135 mph top of 4th gear.
