Being "stuck" with a 14X6 and G70 isn't necessarily a bad thing.

I was talking with some of the heavy hitters in FAST about wheel and tire combo's. The general consensus was that there was little real world advantage to a 15X7 wheel with a 60 series tire over a 14X6 with a G70. Weight, rotational force and rolling resistance all come into play and work against any gain in traction from the wider tire. These little Wide-Oval/Polyglas tires hook pretty well! Steve Vanderwall was able to pull a 1.60 sixty foot on a set of G70-14's! Many guys are able to lift one or both front tires!

Another note- Conventional wisdom had guys keeping the pressure fairly high in the bias ply tires. The thinking was that it increased traction as it kept the tread from cupping.
Lately many of the guys in FAST have been lowering the pressure in the rear tires and have been seeing the sixty foot times drop as well. My last time out I dropped the pressure down to 24 psi and my 60's dropped from around 2.0 down to 1.90. That's in a 4100 lb. car with a 3.31 rear.

Note the wrinkling sidewall.
