Gears
What is my best option for changing my gears. I would like to really go with some 3.90's but I don't want to pay over a thousand dollars for a new diff if I can just change the gears. Does anybody have any ideas or somebody that does gear swaps with me just sending in my diff. Anything would help as I am really wanting to do this while I do my clutch install. Right now I have a 2003 Z06 with stock diff if this helps. Thanks

I went with 3.90's and love it! I was lucky enough to find some guys near my area that have done it before, it is A LOT of work. There is a guy who has step by step who did it in is driveway...I will try to find the link for ya.

There's alwas a first time. How about you doing this, then after a couple thousand miles (making sure it all went well and no whine developes) creating the write-up for the rest of us?

Due to the fact you can't remove a carrier in 30 minutes (more like 3-5 hours)... no one wants to take the risk of DIY.

Even if I have everything I need, I'll still go and buy a Z06 carrier, and I'll still have it installed for only a few hundred more (which includes shift point alterations). Just not worth it to me. I've had to play with my TA's rear end several times, first with 3.42's, then 3.73's, replacing bearings etc. For the extra couple hundred, I know it will be professionally installed in a few hours.

This has been mentioned before; but we're not in the old days when Camaro, Chevelle, and Mustang rear axle ratio changes would take just 30 miunutes by an experienced shade tree mechanic.
If you made a mistake - and found out after a couple hundred miles or so...correction was just another 30 minutes away.
Just to R&R the complete C5 carrier (has to be completely removed from car in order to change the R&P) is about 4 hours by someone that has done it before. You'd grow very irritated during the R&P swap learning process if you had to re-do it a couple of times until you got it right.
That doesn't mean you wouldn't get it right the first time; but the penalty of not being lucky... scares many away (including me) from ever trying.

I believe it's Kent Moore that sells the "special" Getrag tool set. Then the "shim pack" is about $200; with many more shims than you'd need... btu it's not sold for a single useage. I've "heard" that special sized shims are needed for the Getrag ??????

I did find out that there are full instructions in the service and unit manuals. Now I just have to find out what the price of the tools are. I called Kent Moore and they don't have a kit, you have to buy all of the pieces separately and they didn't know what they all were. They said it is also listed in the service manual.

Reminds me a long time ago when I was very young. I was replacing a hood on my car at a friends house and had to remove the wiperblade arm. The service manual stated to use GM tool Jxxxxx. We were about to go out looking for that "special" tool, when my friends cousin stopped by (an auto body guy). We asked if he knew what that tool was and he reached into my toolbox and pulled out a screwdriver.
