Gears?

[sambo60]

I've read how much people love how their gears improve their performance. I was wondering what you guys think. I've got a 96 Cobra with about 625 rwhp with a vortech supercharger, and many other engine mods. The only reason I'm not sure about putting different gears is traction. With stock gears and my motor when it had 420rwhp with a s/c spun the tires in 2nd a lot. I'm going to be putting on 315's so i don't know if that will help much. I was wondering what you all thought about getting 3.55 or 3.73 with that much power?
Thanks

3.55 would be good with that kinda power.

yeah, even 3.55's would help you a lot. SN-95 manuals had really high (low number) gears
