I'd go with these

And like blownhemi said, you'll probably need to make more HP
With some suspension tuning you should be able to floor it out of the hole using the MT ET Street Radials. Since we don't know what kind of 60 foots you are turning now, it is hard to estimate how much you would gain from the additional traction. I have gone as quick as 1.56-1.57 60 foot on the 235 version in a light car (3050 race weight).
With a great 60 ft, you should be able to reach the 12.60s. You are going to need to tune and find some more HP or you need to find a way to reduce the race weight.
Quick tips:
Reduce rotational weight: light weight wheels, aluminum drive shaft, aluminum drums... reducing 1lbs of rotational weight = 10 lbs of static weight
Do you need the spare tire, jack, lug wrench, subwoofer, or golf clubs in the trunk when you make a pass at the track?
Only run with 1/4 tank or less of fuel.
Pump the front tires up to 50+ psi for your passes at the track. Don't forget to drop the pressure when you are done at the track.
On an 8" rim MT ET Street Radials like 14-15 psi. Make sure you check the pressure before every pass.
