Brake Info Needed

[GT-PASSAGE]

Hey guys,

Need help! I am doing a brake upgrade and its driving me nutts!! The plan was to go to R34GTT brakes.

So far I have:

GTT QFM Pads front and back

GTTRear Calipiers

GTTRear DBA slotted Rotors 297mm x 30mm

Braided lines being custom made

Now the problems:

I bought R34GTT front DBA Slotted rotors of ebay for $299, they arrived and they are R33GTR Rotors 324mm x 32mm

Can't find front GTT calipiers.

Question:

Will the 324mm x 32mm Rotors work with R34GTT Calipiers (if I can find them) which normally have 310mm x 30mm???

I have 17 x 9 rims so space is no problem.

I have look though whole site to find but I can't see any info on this specific combo.

As it happens GTT front rotors are friggin hard to find also.

Hi Gary,

I wouldn't try using the larger rotors with smaller calipers, you'll just wear a nasty groove in your discs at the outside and have the pad running on an unmachined surface on the inside. I'd send them back and keep looking for what you want. Alternatively can you use Brembo calipers? They come up from time to time and you already have the discs.

Or maybe better still switch to R33 GTSt/R32 GTR Sumitomo calipers and rotors? The difference between 297mm and 310mm is probably not worth the hassle.

Cheers
