Rda Rotors & Ebc Pads Group Buy 2009

[rs73]

How thick is your overall rear rotor diameter? according to RDA's catalogue, the rear R33 non turbo has an 8mm rear rotor thickness, being so thin, it is usually made as solid disc. There were a few ppl bought RDA7692 with 8mm thickness and it fits ok to rear R33 non turbo...

[r33linerider]

rotors on car are 15mm thick, supplied rotors are 10mm thick (there 8mm on the end due to a 1mm tapered lip on each side)

so 5mm thickness difference

ps all other dimensions are identical though

[rs73]

That must be because the old RDA7690 is no longer in production... that was 15mm thick, and was officially for a R32 GTS.

RDA catalogue only have RDA7692 listed that will fit within your rear caliper... 15mm vs 10mm is only about 2.5mm less on each side

so should be no problems... there were a few other R33 non turbo owners who bought RDA7692 previously and they didn't have problems fitting them on. if you do, let me know.

Cheers, Rianto

possibly a stupid question... but can you oversize the rotors and order GTR's one for a GTT?? or do you need bigger calipers to match?

the rear discs on my car (standard) just look pretty damn small...

[rs73]

no it's not stupid question.

it is possible, but the onus lies on you to fabricate or get someone to fabricate caliper adapter or finding an adapter to suit. mind that R34 GTT rotor's hat height could be different to GTR, so the position of the rotor might be different and you may need to consider the repositioning in addition to the diameter difference...

[SS8_Gohan]

apparently the difference is very little, this is from a friend who was looking at the RDA line-up

"Hey do you know if the GTR rotors fit your Skyline? As far as i can see from the spec sheet they GTR ones are 324mm vs 310mm and th eonly other difference is the GTR ones are 53.8mm high vs 53.75mm..."

so that's a .05mm difference, which doesn't sound massive.

I'll start a thread in the braking section to see what people think, if it's not a huge job it might be worth getting bigger rotors if the price isn't much different.

Actually, is the price much different between standard slotted front/rear for the GTT and GTR?

[Wacky Dee]

probably not worth the hassle Daniel .. I'm sure Nissan engis knew what they were doing when they decided on the rotor sizes. Besides most of the braking is at the front due to the weight of the engine which is why the discs are bigger at the front. Slotted rotors should give you better than stock braking anyway.

[SS8_Gohan]

don't know much, but i'd imagine bigger discs would give you better heat resistance as there is a greater surface area to dissipate the heat, and if there isn't much to modify and the prices are relatively similiar, could be a cheap upgrade ontop of the slotted upgrade

[rs73]

price wise front R34 GTT & R34 GTR is the same

but the rear R34 GTR is the same as the front (in slotted) and the R34 GTT is cheaper at the back.

R34 GTR front 324mm rear 300mm

R34 GTT front 310mm rear 297mm

It's only 14mm difference at the front, it's probably not worth mocking around with caliper adapter and stuff for such a small upgrade.

Unless you have an R33 gtst with 296mm front then some people upgrade this to a gtr front as there is more difference in size at the front.
