What do you think about 4.56 with a t56? Blew the rear end up last night and I know the ring gear broke. It made that classic sound. Bang, a loud wine slowly turning into a clank, clank, clank and then followed by several BOOMSSS! Think im going to try a 4.56 gear this time. I dont think it will be to much for the street with a 6 speed. Plus does anyone know what series carrier comes in these cars stock. I think its a two series carrier but im not sure.

Dont plan on launching in second. Just want more gear. Im sure its going to burn more gas. Just wanted to know if anyone else is using a 4.56 gear.

The person I bought the car from said it had 4.10's in it but the car will run 150mph in 5th at around 5600rpm. I dont know, I have to get the cover off the rearend and see what is really in the car.

If I were you I'd save my money and buy a 9", 12 bolt or S60 rear because you're just going to keep blowing the stock rears with a t56, trust me I blew 2 sets of 4.10's before I finally said screw it and got an S60 for my car.
But a set of 4.56's in sixth gear is 2.28 final drive which aint bad.

Well im going to get the 4.56's now. Plus I think they hold up a lot better than a 3.42 due to the fact of the size of the pinion. Less stress and strain.

4.56 gears will be quite a bit weaker than 3.42's, think about it. The 3.42's have less teeth on the ring gear making them quite a bit stronger, since they are thicker. In a better rear end such as a s60 or 9" I would say go for it, but not in a 10bolt. Good luck!

I have broke more 3.42's and 3.23 in a 7.5. I have never broke 4.10's even after grenading a carrier. Just my experience, less teeth means faster rotation which puts less stress on the engine and rear end.
