I have been hearing rumors in the track rat circles that issues over the Z06 rear end breaking exists. I do not want to hear this since I plan on tracking one next year. Anyone in the know out there who can shed light on the topic? This is a serious post, not just something to incite. I plan on retiring my GTS next year in favor of the Z06, but when stuff like this surfaces I pay attention. I had not heard stink about this until I was at Sebring last week.

I heard the right output shaft is weak link, every car has its weak link, the z06s might be what I just mentioned, but I punished mine for the last 20k miles and nothing replaced yet

I've heard of diffs busting during hard launches at the strip but not at the track. Maybe some of the guys who track there cars can chime in.

My 01 has 20K miles on it...15K hard racing/track miles - no mechanical failures of any kind. The car is bulletproof...just drive and shift smoothly and it'll last forever. Just keep replacing the brakes, rotors and tires.

No worries at all on the track, it's the drag strip that may cause some issues if using sticky tires.

Hello Greg.

Yes, the rear has issues in a road course environment. Main issue is heat.

Drag Racing causes other issues as well.

I suggest that if you are tracking the car (Road Course) you at a minimum install a quality synthetic gear oil and serioulsy consider a dif cooler. (Tranny cooler also).

For the ultimate C5 dif I suggest you have Phil at DTE, a site sponsor build you one that will much better handle the track environment.

Here is a link to his site and the dif's he builds.

You can PM or email me if you have any more questions or info.

Thanks, Perry
