R34 Gtt Stock Rotor Thickness?

[Wacky Dee]

I need to get my brake rotors/discs either machined or replaced as the rotors on all 4 wheels are lipped and I'm getting new brake pads soon. But since my tuner/mechanic is a fair drive away and very busy I'd like to find out if I just need to leave the car with him to get the rotors machined or if i need to buy new rotors, so as to have the car in/out asap ie. so I can buy the rotors now and take them to him instead of mucking around in case they can't be machined.

Anyway, what's the stock R34 GTT rotor thickness and what's the min. legal that can be machined? I'll get them measured by a local tyre place so that I can make a decision to either buy new rotors or book in machining.

Minimum up front is 28mm, and minimum for the rear is 16mm.

thanks mate. Just to save someone else the trip ..GTT fronts are 30mm and rears 18mm when new, that's a great resource for looking up rotors sizes/thickness someone should sticky it

[Lupes]

Yeah it's good, it's where we get all out minimum thicknesses from at work when servicing cars etc.

Generally speaking, most rotors can wear about 2mm from new before they're stuffed.

just another quick Q, is it possible to reliably measure the thickness without taking the wheels off ?

[Lupes]

Generally it's easier with the wheel off.

Use a vernier caliper to measure, anything else is generally too inaccurate when you're checking rotor thickness.

if you wanted to be really anal you could use micrometers.
