Skyline/silvia Brake Sizes And The Rotor Sizes For The Calipers?

[Tim N]

hey i had a little search and couldn't find a post that had the specs on all the skyline/silvia caliper types and size rotors they use. I'm adapting some to my datsun 1600 and i want to know my options.

Would appreciate any help.

Majority of the caliper types would have been 4 piston front and 2 piston rear calipers.

Nissan branded Sumitomo calipers.

R32 GTR V-Spec / V-Spec II

R33 GTR / R33 GTR V-Spec

R34 GTR / R34 GTR V-Spec / V-Spec II / N1 / Nur / M-Spec

Would all have Brembo calipers.

thanks heaps for that and which one are cast iron and which are alloy?

and i've adapted a 280mm x 30mm rotor to my strut, i heard the r32 gtr calipers are alloy but it looks like they run a 296mm x 32mm rotor, is it possible to run the gtr caliper with my 280mm rotor??

If you are referring to the material used to make the rotor, I believe most would be cast iron.

Not till you start buying aftermarket rotors they start using alloy metals.

No, the question was which calipers are alloy and which are iron.

Regardless of which are which above, you cannot run the bigger GTR calipers on 280mm diameter rotors, because the caliper does not sit over the rotor properly, it hangs off the outer edge. The R32 calipers need 296 mm rotors (and so you could run them on the R33 rotors which are 296x30). The various V-spec rotors/calipers are for even bigger diameters and so you can't mismatch them onto smaller discs either.

The length of the legs of the calipers is the main difference. R32 caliper is essentially the same as the R33 caliper, but the R33 has longer legs to suit the bigger disc.

All of this becomes a bit more flexible if you're going to be using struts that will need an adaptor to mount the caliper anyway. What were your plans?

I must have missed his post while posting my answer.

Or I would have known

Like what GTSboy said.

If you want to run R32 GTR calipers run the R32 GTR rotors.

[GTSBoy]

Yeah, if you've adapted the 280mm rotor to your strut, then it is trivial to put the bigger rotors on with the appropriate calipers.

Generally the Skyline ones are alloy, the S-chassis are all iron. There is a significant weight difference.

ie. R32 GTR, R33 GTST, GTR, R34 GTT, GTR are all alloy.

S13, 14, 15 are all iron.

Unsure of R32 GTST material. There is a silvia page somewhere on the interwebs which describes all this and more.

If you want alloy caliper and also run 280x30mm rotor, then you should pick R32 GTS-t/GTS-4 caliper.
