rear axel ratio

[Trans Am Ws6 Man]

i was wondering if someone could tell me the benefits of a 323 rear and a 342 rear and could somebody tell me why the 323 was called a rear performance axel ratio what could you do differnt

Performance axle (3.23) was an upgrade option from the 2.73 with steel driveshaft on the A4 cars. 3.23 also has a 3 series carrier and alum driveshaft, 2.73 a 2 series. 3.42's and alum driveshaft were standard on the M6 cars. My car originally came with 2.73 and I swapped in a 3.42 complete rear from a M6 car. Hope this helps, not sure what you're asking.

3.23 is simply the ratio which is better expressed as 3.23:1. That means that it takes 3.23 turns of the driveshaft to make the rear tire go around 1 time. Performance ratios are always numerically higher -- in our automatic car a 3.73 rear is considered a good axle ratio. M6 cars, because of the better overdrive gearing, generally utilize 4.10 gears in the rear for performance.

With 4.56 gears and a 6-speed, pulling out in 2nd gear would almost as easy as pulling out in 1st gear with a 2.73 gear set. Clutches last longer when used with 4.10's, 4.30's. 4.56's, etc
