where does the GTT R34 fall in this scheme? I am thinking of Brembos but not sure if to worry as I may just change pads and get some braided lines and cal it a day. I will also be swapping with some crossdrilled as well.

If you put Brembos on your GTT you will need the correct size discs for them. I think the standard GTT disc size is 310mm.

trinigt if you are running a standard car (exhaust air filter) the standard brakes will be fine just change the pads to ebc red or yellow with some braided brake lines and some dot 5 brake fliud and you should be fine,if your car has a lot more power then put some brembos on it from a gtr a very good upgrade,but they are not cheap even secondhand they are expensive.

So what is the difference in Pad size for R33 GTS-T to GTR?

**Bubble** · 9th September 2008, 04:45 PM

The R34GTT discs are 310mm

The R33GTR/R34GTR are 324mm

The pads are a similar size, but a different shape between the two.

The biggest gain with GTR Brembo calipers is the larger disc size, which dissipates heat better.

Anyone knows the rear rotor diameters for the GTT and the GTR R34?
