3.42 or3.73 ???
I would like to change the rear gears in my Z and am considering 3.42's or 3.73's. Your thoughts, opinions, and advise would be greatly appreciated. If possible let me also know your performance experience. I have the stock 3.23's with an automatic.

Re: 3.42 or3.73 ???
On my 94 Z28, my first upgrade was to 3.73s. They were indeed fun as hell, but the streetability was pretty low. With gas prices the way they are today, ew.
I later dropped down to a 3.42 and was VERY happy. Perfect middle ground. I then added a 3200 Vigilante stall and WOOOO. The torque was just sick. I was cutting 2.0 60 foots at the track on STREET tires.
I highly recommend a combo of 3000-3200 stall with 3.42s. Worked great with my setup. I also had a nitrous kit, which I never go to put on, but it would have made for the perfect powerband on that setup.

My '94 is in the process of getting 3.73's put on as we speak......everyone I've talked to about it has told me that 3.73's were the best way to go for me, especially since I'm starting out with stock 2.73's.
I've been researching and asking around about this for a few months leading up to now, and the only bad thing people were telling me is the whole gas mileage thing.....otherwise, I have been told that 3.73's would be sick for my car. I, too, was initially going to go with 3.42's.

I've never heard anyone breaking it that easily with 3.73's. If you're hard on anything it'll break.

Either that, or you made a habit of brake torqueing and burning out.....
