Brake Upgrades

[Lupes]

Hey fellas.

Looking into brake upgrades for my R31, and I have read and heard lots of conflicting information.

Over at the R31 Skyline Club, we have this table:

My original plan was to use a early R32 GTS-t caliper with the later R33 GTS rotor. As far as I'm aware, this is not a problem.

The reason I would prefer to use the R33 GTS rotor is because it is 4-stud as standard, which means no re-drilling, which means it's engineerable. I'm trying to keep as legal as possible, I want my car engineered as it's going to be my daily.

Now, I have heard that the early R32 GTS-t calipers which suit the 280mm rotor aren't 4-pot? Is this correct?

I was under the impression all R32 GTS-t calipers were 4-pot.

Any help would be greatly appriciated.

Cheers.

hey mate

with my limited brake knowledge all i know is that the R32 GTS-t Type M calipers are 4 - pots, where all the other ones are not.

and The type Ms are the late model R32's - so 89, 90, maybe even 91 modles are only 2 pots.

I am not 100% on this - the only thing i am 100% on is that only Type M's are 4 pot calipers.

hope this helps you in some way

cheers

My 1990 Type M brakes were 4-pot.

What about changing hubs? not sure how they do it but the silvia boys and na skyline boys do a 5-stud conversion.. might want to look into that and run the 296mm rotor/33gtst caliper setup.

I have thought using 5-stud hubs up front, but I would prefer to keep the car using 1 stud pattern, and not really keen on getting new 5-stud axles made up.

The main question I would like to know is whether early R32 GTS-t's which used the 280x26 rotor are 2-pot or 4-pot.

If they're 2-pot I'll just look for some R33 GTS calipers.
