What are the weak links?
Hey everyone, this is my first post so please be easy on me if I asking a question hundreds of people have already asked. I own a 04 Z06 and don't know how strong it really is. I have looked everywhere to see if anyone could tell me how strong the rear differential actually is. If I took it to the drag strip and used slicks am I going to burn the clutch out first or is the rear gears going to crumble. I dont want to drag race all the time but maybe once or twice to see what my car can do. Its bone stock now besides corsa exhaust. I would like to add some performance mods slowly and maybe get up around 550rwhp. What parts will fail on me first?

Well the entire drivetrain is a weak link, everything from the clutch to the rear has been know to break. And adding more HP will only make the chances greater, but hey if it breaks there are a lot of good aftermarket options that are a lot stronger.

C5Z06 is a very, very stout and reliable car. I owned two in which I made 500 drag strip passes at stock power levels (most on DRs) and never broke anything.
Remaining trouble-free depends on avoiding the classic driver errors that provoke wheel hop, slipping the clutch significantly, failing to maintain the clutch fluid, or missing shifts due to poor technique.
You will do yourself and your wallet a huge favor by perfecting your driving before adding mods that produce more rwhp.

^ Listen to Ranger... these cars are very stout and the trans/diff are very strong.
With high power levels on stickey tires you can break the driver's side output shaft (not 1/2 shaft), and some people have cracked the trans output shaft or the case from having the trans/dif twist against each other.
Most who do moderate drag racing get a hardened output shaft (in the differential) and the DTE trans brace.
Keep up with swapping your clutch fluid in the reservoir or the pedal will start to get stickey.

My 03 Z has 54k trouble-free miles. It's been on several long distance trips with another one in a few weeks. I use it to commute to work and it's also been down the drag strip several times. Unless you do major power adding it should hold up fine. BTW, my car's also mildly modded.
