12.1@ 111
1.6? 60'
Tires? Narrower than most(7.7"), and a little shorter(25.5"). So yes, it is very possible.

11.54 at 123 mph on 275-60-15 Continentals with a 1.9 60 ft

12.4 @ 110 with Pep Boy Futura 255 16's, 1.84 60 foot. I went to the track not planning to run and got talked into it. That was done with 91 octane and 16psi.

Sumitomos are pretty favorable on the street against Nittos, where you can't do a burnout. They don't make any size we can use in 15s. Mine are 16s and have a good speedrating and they are cheap. They're good for easy 20,000 miles.

Ya guys think a 12 is possible with 215/60/14 Firestone Firehawks? I know, I know...time to get new wheels and tires.

BTW... I do have the parts to run low 11s, maybe high tens when it gets tuned....just gotta tune it.

If you can get some traction, then you should be able to get some good 60', but your top end is going to suffer. That is one heck of a short tire(24" compared to a GN stock tire of 26". Is this on the GN? ....or did you mean 15, not 14? Which would still make it a little short(25").
