R32 GTR Brake upgrade

[R32GTR]

Has anyone here upgraded thier GTR's brakes from an R32 Nissan calipers and rotors to the R33 Brembo's.

Is/ would this be a difficult job?

Is it even worth it. Do they make much difference.

From what I can determine the R32 V-Spec's all had the same Brembo calipers that the R33 has as standard. Can anyone confirm this?

Thanks in advance.

i can confirm r32 vspec brembos are the same as r33

cant help you with upgrade advice tho *shrug*

pad area difference does not seem all that great. Will need 17'' wheels and I think the V-spec 32's ran a spacer plate at the rear to get the BBS wheels to clear the calipers, from memory.

I explored the option as I had access to some cheap calipers but by the time wheels etc became involved it got too expensive. most people I know with 33's are running after market brakes anyhow.

I went to pagid pads as a short term solution till I decide/justify a wheel and tire change.

If you are on a budget then id stick with only getting some nice front rotors.

You will have to decide whether you are happy running 16" rims or want to go bigger.

As the R32 GTR caliper takes a 32mm disc, id be looking at either a 296 (or thereabouts to fit inside a 16" rim) or about a 324mm (17" rim).

Id go for the two piece rotors as the aluminium hats add to the cooling capacity of the brakes... then with some good quality pads i would think the brakes would hold up just fine.

I regret not having forked over the extra coin to get the 2-piece rotors, but the 324mm front upgrade on my GTSt works wonders with the std calipers.

I recently bought an R32 GTR with R33 v-spec brembos on the front, with stock Nissan callipers on the back with cross drilled and slotted discs.

It brakes awesome! Pulls up *alot* quicker than a standard r32 with nissan callipers. As for the costs involved in the conversion, unsure, but in my opinion it is a worthy upgrade.

Its interesting to hear that you can physically tell that the car brakes better, by better i take it you mean shorter distances.

My experience has been the car stops about the same give or take, but does so with much more feel in the pedal and at the track does it a hell of a lot more consistantly.

My thoughts only but for one stop the std brakes offer more stopping potential then most sets of tyres, so unless you step up a notch as far the quality of the rubber you are using then you wont reap shortened stopping distances. Only more consistancy

Wish i had the money for 6 pot Endless Calipers and rotors, the blue would look so nice against my silver paint. (im a dreama)

Thanks for your replies guys.

The reason I am asking is because all four of my standard (cross drilled) rotors have developed large cracks. As I am going to have to replace all rotors I wondered if it's worthwile going to better calipers on the front at least.

Roy you have me interesed in the upgrading rotors idea. I am already running 17" x 9 rims so there is plenty of space under them, but how do you put on larger diameter rotors with the standard calipers? Do you have to adjust the location of the calipers? Do you use different pads?

The car gets the occasional track day so I won't be getting cross drilled rotos again - Slotted only.

Anyone else done this conversion?

[Roy]

A bracket is used to locate the std caliper to suit the new rotor.

If your not going to be doing all that much track work then some one piece rotors, say 330x32mm or similar may be the best bet. Even cheaper then the two piece and mine have put up with a flogging for over the last 18 months now at numerous track days. Although yor car is bit heavier.

Again my thoughts only, but if you have std brakes at the moment then simply throwing bigger rotors and calipers at it may not give you the result you are looking for, especially considering the $$$.

You would really need braided lines, properly functioning master cylinder/brake booster to be sure to be getting the best out of them. I say properly functioning as ive heard of and experienced first hand worn master cylinder/brake boosters that are hurting braking performance. Not to mention tyres that can keep up with the improved braking force.

Some DBA replacement rear with some larger aftermarket front rotors (or other brand, how much can you spend) with some legal braided lines, good fluid and good pads will much improved braking over std. All up i guess it will cost about $1500-1700 fitted.

When the front rotors on my 32 gtr cracked and I replaced them with some DBA 4000 series Slotted rotors and some decent pads. They survived a Wakefield park track day with ease, very happy with the result for minimal money

[Roy]

... and looking at the speed you were carrying into the breaking at turn 1, and your lap times, they perform pretty well too.

Whats decent pads?

[GTR032]

My top speed down the straight was 176km/h, was recorded on my RSM.. Some cheater tyres will see that improve a little.

Pads were only Bendix Ultimate, nothing special or expensive but did the job

I have these on my R32 GTR, it should be on the road in a few weeks. :D I've heard they are a very good brake kit. Endless isn't very well known in the UK.

[Therapy?]

i'll agree with GSR 13S that the DBA 4000 series rotor's are excellent for the price. They transformed the braking performance of my land barge of a soarer single handedly

I'm curious to know how expensive it'd be to machine slotted and/or crossdrilled rotors, anyone know?
