New to mustang drag

[Dhoe]

I just bought my first mustang. 2000. While I was replacing the front control arms I measured the springs. They were almost 2.5 inch's shorter then stock. I want to run a good drag tire this summer but I'm alittle worried about the fit with the lower rear end. The car came with a set of 20s and 15s rims. I'm running new tires on the 15s now to teach my son stick shift. I did find a tire that you can run on a 20 wheel. I've always been a truck guy so please excuse my questions.

Welcome! Do you know if it has the stock 3.27s in the rear end? And if it has a good clutch in it? Stock one will burn at the track.
I'll tell you what I use, I still have stock-internals 3.8, I have a manual and 3.73, but the aftermarket trans 1st gear plus 3.73 has the same overall ratio as stock, and my bias ply ET Street R tires are way too much ha. Gotta launch at redline at 30+ psi and I can still bog down below the torque band once they hook. But, they sure do take a beating and I'd rather chew them up at the track than my street radials.

As far as I can tell the rear end hasn't been opened
