Brake Upgrade Advice Needed

Hi Guys,

I was given a complete brake setup from a R32 GTR yesterday (as he had upgraded) and he said it would be a good upgrade for my S1 R33. By the looks of it I can tell that the disks are obviously drilled compared to mine which are not but what are the other advantages? Should I also swap over the calipers? It all looks to be in good condition so pretty keen to see how it goes.

Any advice much appreciated.

Cheers

Andrew

Mate to my knowledge, all turboed R33's have R32 GTR brakes on the front, same calipers and rotors. And i think rears too. If the rotors are drilled then maybe they're the optioned brake packaged Brembos, in that case it would be an upgrade. If they are i'm not too sure of fitment but i think they're a bolt on swap.

If you intend to use the car on the track, i personally would not use drilled rotors, as they are prone to cracking when they get really hot.

Early model 32gtr calipers are the same as 33gtst. The later model 32gtr had Brembos, which are much better. So if the calipers have BREMBO, across the face, then fit them.

Slotted rotors are the best option

Cheers guys. I just had a look at my car and yes it appears that the calipers are the same, they are "SUMITOMO". I am not intending on using the car on the track, just road work so perhaps swapping to the drilled rotors would be a good option, what do you think? I have included a pic of the rotors (front and back), is it stock R32 gtr stuff?? Worth swapping it for my disks?

mate your 33 brakes are probably better

same size calipers

same diameter discs

gtr discs are 4mm thicker new (but i bet these arent new)

gtr discs are cross drilled and can crack

gtr calipers will be older and need a rebuild sooner

if you want an upgrade do it in this order:

new motul rbf600 brake fluid flushed through

new dba/rda discs

remove your brake backing plates

new brakes lines (braided or rubber as long as they are new)

master cylinder stopper

rebuild your calipers with new seals

or most importantly get better tyres if your brakes are fading

      Uncle Duncan Yeap, FI Interchiller  Works well, normal IAT's cruising with the WTA only went from 50°c+ to 25-30°c with the interchiller  Before, when on it hard, the IAT would see 80-90°c, now, the highest has been was around 38°c IIRC IAT is measured under the blower hat I recommend it for the street or strip where your only on it hard for 10 or so seconds, but it wouldn't be efficient for sustained track use as it would heat soak from the AC turning off or whatever it does during WOT to protect the compressor It really needs the AC running for it to not heat soak and keep the WTA coolant chilled My WTA coolant temps when just cruising is around 2°c

      Hey Mark...sorry to interrupt your career change to hair dressing... but...did you ever fit the interchiller to the commodore, and if so how was it? And, who made it?

      I've been pondering this, I really enjoy the convertible thing, for me, it's like riding a motorbike, without all the issue of riding a motorbike, mainly, my old sore arthritic joints getting beaten up, and, being able to do it in shorts and a T-shirt and not needing a helmet and all the other gear required, especially like wearing jackets and pants in the summer, or needing 6 layers of cloths in the winter, or not having wet weather gear handy when your 100km away from home on the bike when it decides to start raining As for the hard top and its Coupe look, whilst I do lose all that open top feeling that I really enjoy, from my experience with the NB with a detachable hard top, the cabin is a much nicer place to be, the difference in noise for one, a hard top quietens down the interior, alot, with the soft top up or down it's pretty noisy, which, after 5 or so hours, can get tiring But, as you stated, the detachable hard top totally changes the look of the car, in a really good way, and for me, the look of a detachable hard top is so much better than the PRHT which looks more like a after thought with its weird bulbous rear roof line For me, the minimal effort of putting in on, or storing it after removing it, is well worth the time and effort for the look alone And yes, I'm sure the next owner will be grateful for it as well.......
