how much HP on a M6
rear might hold 3 hard launches
you cant race 500rwhp on a 10bolt with a manual tranny and be hookin hard of the line, just dont work, not long anyway, not to mention you would be nuts to leave a 3.23 gear in a manual car, thats just waaaaaaay to much gear, you should be 4.10 or so and in a 12 bolt, you would kill clutches fast on a 3.23 gear leaving hard anyway, not to mention the massive bog you will get
if you go to a 4.56 you're probably gonna have to shift into 5th
with your power level you shootin for i would run a 28 inch tire and a 4.30 or 4.56 gear if you dont plan to rev past 7k, im trapin 131mph at about 7000-7100rpm with a 28w tire and 4.56 gear
