I've been doing a lot of reading about axles, and I have a few questions I haven't found answers to, it seems most of the info is about Z06 axles. Did the axles change in the base cars in 2009? At what point should the axles be upgraded? I'm planning on doing gears this winter and wondering if I should upgrade the axles while I'm at it. Thanks
axles changed in 09 along with the hubs and ebcm. I'd rather snap an axle then a diff. don't know what you have in terms of power but if you stay away from wheel hop and dumping the clutch you should be good

Do you know what changed about the axles and hubs?
the EBCM was replaced with a new model and with it the speed sensors in the hubs are different along with the axles. the Zr1 has one axle bigger than the other also.
the 09Z axles are very tough, but the 06-08 Z axles can hold up big power too.

I read that link before, and it's part of what has me worried, but doesn't really answer my question. Right now the car is stock, but with just the gears the torque at the axles will be about what a stock Z06 would have at the axles, and I've heard of them breaking their axles with the weaker style. So I'm worried that with the base axles when I start adding a bit of power I might be in trouble, and I'd rather it not break and cause collateral damage. And I figure when the diff is out would be an ideal time to change them.
Dumping the clutch with a drag radial and good prep, or wheel hop will snap axles. I have an 09Z and maybe 250 passes and haven't had an issue. Both my friends Alex and Joey have 06 and 07 Z's and snapped 2 each. But they also snapped their BIG z06 diffs too so maybe they are a bit too agressive to start. Haven't seen collateral damage. I've even swapped axles at the track and had them right back out. If you go overkill, you are likely gonna snap your diff instead of an axle. Usually the axel snapped right at the starting line and you go nowhere. I see them like a fuse. Rather pop a fuse and replace it then have to replace the entire circuit.

The Axles from the 08, which is what I have are weak, I broke my axles twice, the C5 axles are stronger than most, but the most important things are the output shafts in the rear, most people change the long output shaft to the hardened shaft, I changed both because they snap very easy, RPM or G-Force sells them and its very easy to change by any knowledgeable person. The rear will have to come out to change the shafts
The 2009 and later axles have a 33 spline count (and is larger in diameter) on the end by the brake/hub so a C5 axle will not work as they are only 30 spline. The C6 2006-2008 axles are 30 spline on the brake end also. So if you have an 2009 and later you got to stick with the axles that are on car and can not do any C5 stuff.

For a visual here's my 09Z axle vs my buddy Joey's 06Z axle. Clearly beefed up
