225/45-14s. Comes out to a 21.97" rolling diameter. Stock is 24.88". Your gearing is going to be drastically changed. First gear might not even last you until 60'. It'll be quicker than hell. I would also make sure that you have a maximum of -0.5 degrees of camber in the front. That will ensure full contact patch at the hit of the throttle.

I still think that the 45 series sidewall is too short. Not enough room for the sidewall and contact patch to work together and create good grip. If possible, go with a 225/55-14. The rolling diameter is going to be 23.74". It'll still be way quicker than because of the change in effective gearing and the fact that this tire size is going to be lighter than stock.

The 215/60-14 would be "my" preferred choice if going with a 14" setup. Taller sidewall, ability to run lower air pressure and create a larger contact patch. The slightly narrower tread width should help in top end speed as well. Less rolling resistance.

Just so you know, I'm going to be getting a set of M&H Dragmasters for slicks. They are going to be in the 8.5/24.5-15 size. Just slightly shorter than stock tires, good sidewall size and sticky icky icky. But I'll still have a set of drag radials for street legal days.
