Sweet, sweet ride...equally stunning on the driveway and the track...must be a blast to bomb around in...

Cheers mate!

yeah she sure is hell of a lot of fun either way. can get a bit tempting to do silly things on the road with the power though, but i generally manage to keep it to the race track *wink wink*

Nice wheel and tire combonation man

Also nice to see you leading the Pack ehh

Just the way it should be

Very nice car, I especially like the black around the windows instead of shiny aluminum. Nice touch!

Yeah were the fastest in class. that picture was from the vintage regularity last year which is coming up again in a few weeks. absolute ball of a time. im generally overtaking the back of the pack after 2-3 laps :devious:

as for the black. Thanks!! most people seem to think the chrome looks better

but personally chrome and silver was too much, and the black makes it look kinda stealth like so i definitely prefer it.

That's stainless steel isn't it? not aluminum.

Noticed you fitted XR8 rotors and 4pots. Was this hard to do? Just looking at 4 pot options now (in New Zealand)

Theyre only 2-pots but they have about 2 times more pad area and much more powerful pistons than what was on the car (Toyota 4x4 4-pistons), so over stock, if thats what youve got, even over the toyotas, they would be a PHENOMENAL upgrade.

Rather easy to fit. re-drilled commodore rotors to 4-stud patter to fit on the hubs and had to shave the suspension arm where the calipers mount down to a completely flat surface (they have a slight bump. about a couple mm i believe) and then used a shim to situate the caliper centrally on the rotor.

not too difficult but not super easy.

If youre not going to be racing it id honestly recommend the Toyota 4x4 4-piston and solid or vented rotors, much easier to fit and work fine. these were on the car and did a far more than adequate job on the street, the solid rotor just got too much heat soak on the track though. fine for sprints and motorkhanas and "street" racing but could be better for circuit racing, which is why i upgraded.

the added bonus with these xr8/commodore brakes too is that they fit in under the 14" stockies had to use an angle grinder for one spot on one of the fins on one of the rotors that JUST touched but otherwise all good.

**EDIT** the commodore and xr8 brakes are identical i am lead to believe. i also am told that these particular specimens are from a VN commodore, but they are however identical to the brakes on all models of xr8 and commodore up to but excluding the current iterations. i am not certain of this though so some searching for "commodore brakes" on this website and/or hybridz.org would probably be prudent.

Thanks - that's excellant info.

I have an VN commodore station and an XR6T - so will be interested in comparing how these match to the 260z.

But just to clarify - are you saying that the commodore/xr8 bolt pattern matches directly to the 260z? (apart from a shim)

[justin260z]

Yes you are right mr. camo, I guess working around diesel trucks is getting to me (memory loss)

Just curious Tommo, how did you go about painting the trim? Is it powdercoated, did you sand it and paint it?

ohhh... good question. now you mention it i think they are out by a little bit so we welded and re drilled one of the holes. i dont think its out by much. sorry cant be more precise but it was a while ago and i dont really remember, just that i took it to a cnc place and said fix it. whatever they did it didnt cost much, i remember that much.

Justin: Yeah, Powder coated. flat black i think. looks great.
