An upgrade for Z brakes

[JasonNagra]

Well I finally got my 30mm Alum Z brakes. However I need to buy rotors for them, and a buddy of mine forwarded me this link:
http://www.ztuner.com/brakes.php

Since this is a bolt on for the Z, and the Z brakes (front) are a bolt on for the S13 (besides the brake line) I was thinking this would definatley work for S chassis cars as well right? The pricing is a little steep with the rotors and bracket so for the time being I was thinking of only buying the bracket and later buying the rotors from a cheapr source because I already know what car the rotors in this kit come from. The only problem I see for some people is if they're wheels are too small and can't fit the 13" rotors, but I am running 17s now so no worries.

So basically I just want to know if this kit will work for my S13 with 30mm Z brakes?

Thanks, Jason.

Unless I am mistaken, that kit uses the VR4 (3000gt) rotors. That design would bolt on the S13, but there are some issues:

1. It will fit under 16" rims, but you may need to run a spacer to clear the brakes. On the Z32, it requires 15mm more clearance out to the rim to clear the calipers. On the S13 it will require an even larger spacer, since the Z32 wheels with Z32 brakes on the S13 require a spacer to clear.

2. One Z32 owner who ran this setup at the track had the VR4 rotors disc separate from the rotor hub. Notice the holes all around where the rotor disc is connected to the hub. The design if not very strong for serious track use IMHO.

3. The VR4 rotor is closer to 12.4"-12.5", not 13"...

I can offer a kit using Project Mu rotors and Project Mu adapters, which uses 12.75" rotors for the GT-R (R33/R34), unfortunately it is more expensive than the VR4 kit. On the other hand, it does not have the offset problem and the design of the rotor is stronger.

Thanks Kuah!

Yes they use 3000GT rotors. How much do the adapters along with the Mu rotors go for? I would like to do this all at once so let me know. Also like you were saying about the offsets, with the Mu pacakge, it retains the normal Z brake offsets?

The GT-R rotors have the same offset as the Z32 rotors, so the fitment is exactly like the Z32 brakes, other than needing 17" wheels to clear the larger rotors.

Unfortunately the Project Mu rotors + adapters would cost about $600...

Theres a guy on one of these forums that put big red porsche calipers on his PS13 coupe.....really nice car...aero bumper and all.
You could check into that, or....possibly the Z33 brembos??
