The ZR1 brakes are not a direct bolt-on replacement for the Z06.
I think they need new hubs and they will require the 19 and 20" wheels to clear them too.
In the real world, you are unlikely to gain much benefit over the Brembo GT 14" or 15" kits already available for the Z06.
And if you do drive the car hard enough on a track day to notice the difference, the incredibly expensive rotors will need replacing very quickly.
I've said before that the main reason a Z06 still makes a better track car ownership proposition than the ZR1 is the brakes and their running costs.

Given that the front rotors are used on an FXX and the rears on Enzos they total up to around £25k, just for the rotors alone. Godzilla is right though, I don't see much merit in trying to copy a ZR1 because afterwards it will always be a replica. In the same way that there is little interest in the US for replicas of Pontiac GTO Judges or Plymouth Road Runners. If you want to modify your car you should do it for your own reasons, not imitation. However I do rate the front splitter and side diffusers....
I love the look and aero functionality of those parts too.
But how long would the CF splitter last in the UK?
One unseen compression taken slightly too fast and it's time to buy a (very expensive) new one...
A similar design in the cheap, flexible plastic the Z06's is made of is needed.

This doesn't make sense to me. Are these guys respected tuners?
No way will an LS7 safely take this much more power or torque than standard without changing the pistons and rods and ideally the crank. These engines are really built to a budget despite the marketing.

XTR2Turbo and Mitch,thats what i thought! i have asked MTI in the attached thread to see what they say. having said all that the old LS1's used to have to go fully forged at about 500bhp....now guys are making well into the 700bhp (some more) region without problems.No way will an LS7 safely take this much more power or torque than standard without changing the pistons and rods and ideally the crank.

i'll see what MTI say.
dose anyone do a 'drop in' rod and piston upgrade for the LS7??
Chris.
The problem you've got is the rods are about as strong as anything you'll get in there, but in higher power configurations we reckon that they'll be hard on bearings as they're constructed of titanium. There will definitely be replacement pistons, but surely MTI would have to replace those anyhow. I wouldn't expect them to say anything on the forum that's particularly enlightening as they're trying to sell them, not admit to potential shortcomings.....

I'm not sure I completely agree as the splitter mounts the bottom of the nose which has some give in it. Most of the scraping you hear over bumps is the splitter for the radiators in front of the wheels anyhow.
Yes, but the ZR1 splitter juts forward a LOT compared to the Z06's. They also had to strengthen the nose to prevent the splitter pulling it down, so it will be less flexible than the Z06's nosecone where it matters.I'm not saying I wouldn't buy a ZR1 because of it, it would just p1ss me off if I had to buy a new splitter after every spirited cross-country drive!
I agree that forged pistons are a must for MTI levels of power.
As for cranks, don't forget the LS7's IS forged and Katech say they have never seen a single example of the titanium rods failing either.
chuntington, I'm sure Katech will sell you a set of their forged LS7 pistons.
My LS7 was dynoed at 697 bhp and 620 ftlb
None of the internals are standard. I was advised that I would be gambling with them at anything much above about 550bhp.
Mind you I may have gone to the other extreme now and have had a bottom end built that could take 1000bhp.
I was advised that there is no way the standard piston crowns will handle forced compression.
