So my clutch is showing signs of dying a slow and painful death, due to my mild engine mods and the DOT slicks I run.

I have done quite a bit of research, and have put together a shopping list for the clutch replacement, and the "other stuff that you just do while you are there..."

There is NO way I will be ripping the rear end off my car again in 6 months to replace a guibo!!

The list comes to slightly under $8k, so I wanted to get some advice before going further.

I am planning to do most of the work myself (including the diff re-build), but will be getting the transmission done by a local pro (he used to do all of the Aussie V8 Supercars).

I know I am buying a lot of diff shims, but because I'm in Australia, I don't want to wait 3 weeks, 'cos I don't have the right one! Also the reason I am not buying a pre-built diff. Freight from Australia back to the US is more than the core charge!

Thoughts? Advice?

Thanks

 

Wow! That's a comprehensive parts list my man. Good luck with everything. I'm just glad I live in the US. Your list total price is almost half what I paid for my Z.

 

Not exactly advice, but more of a request... please take a lot of pictures! You seem to know what you want; I'm subscribing for future reference.

 

I've had my Z for nearly 4 years. Bought it in LA, shipped it here and had it converted. The conversion cost just over 1 1/2 times the cost of the car.

I like the fact that there are only a handful of C5's in the country, and even less Z06's!

I've spent another $12k on my Z since I bought it, mostly on the usual stuff;
Vararam, Kooks headers & hi flow cats, 'Big 3' axle back, 36 lb/hr injectors, 160* thermostat, MSD plug wires, Motorsport wheels (+1") with Toyo R888s, a HID headlamp conversion and of course a copy of HP Tuners...

I'll probably have to split the job in two to get it past the finance committee, otherwise known as my better half...

My only concern with that, is doing a big takeoff with my new clutch and driveshaft, and spitting the rear end all over the road.

The goal here is to bullet proof the drive train, so I can look a bit deeper under the hood and find some more hp.

 

Took me a little reading to figure out "Guibo". Looks like you really know your stuff, but you never mentioned any trans/diff bracing. Maybe you already have these, so you just didn't mention them?

 

Not really, I just spent quite a while researching... (It's a lot of $$$ to part with, especially considering I'll pay an extra 10% on import duty, and shipping will be well over $1k)

I want to add an ECS trans/rear end brace later, as I don't need to strip half the car out to install it. (and probably a tunnel plate at the same time).

I'd love to do it now, but it's another $400.


What sort of power level do the trans/rear end braces become essential?
