I'm hoping to use R33 GTR Brembo callipers on a project - planning 18" stepped lip rims which will only have internal diameter the same as a 17" rim, but will give me a better rolling diameter with the rubber.

So as my topic title suggests...........looking to find out what are your thoughts for rotor size to suit my application.

Oh also where is the best place to acquire these parts that I will require? - I'm not too bothered.........new or used, happy to receive suggestions for both options.

Cheers.

Use the r33 gtr brembo rotors?

Or get aftermarket slotted rollers for an r33 gtr with brembos?

Im not sure why your asking. Should just post in the wanted to buy section if your happy to go second hand. Otherwise go RDA or DBA rotors if you want new

Keep in mind you can put massive discs on but youll still only ever get the braking force from where the pad touches.

OK.........good point(regarding the surface area of the pad), so what size are R33 GTR rotors??? Thanks. I've had a killer headache all day - sorry if I'm asking stupid questions........my mental state is compromised - but am still needing input :(

324mm front from what I can find, not sure on the rear. Theres people that sell RDA rotors on here, be worth sending them a PM and seeing what they can do for you. If you are just putting brembo rotors on an R33 GTS-t or R33 GTR that didnt have them standard then should just be a matter of buying rotors made for the 33 GTR V-Spec or whatever was equipped with brembos

Thanks for your help Callan. The project is an old holden. I had a great semi-standard brake set up on a R33 GTSt I previously owned, just had slotted rotors and Bendix ultimate pads. So loving Nissan brake performance, I am looking at the possibility of adapting a Brembo GTR brake set up to my 76 model holden.

Love your GTR btw.

Mine's a GTS-t lol

I'm not sure what the deal will be for a conversion like what your doing. Wether you can run newer model/bigger holden calipers etc or if it has to be a custom job. But if you talk to GSL Rallysport: http://www.skylinesaustralia.com/forums/topic/428051-disc-brakes-australia-dba-brake-rotors/

Or maybe email DBA or RDA brakes direct and see what they suggest.

      R32 non hicas power steering solenoid issues!

      By joshuaho96 · Posted

      I don't know if this is accurate. The EPC places the EPS control unit somewhere in the engine bay or somewhere in the interior near the firewall, presumably because the things it's controlling mostly live up in the front of the car unlike HICAS which has a whole steering rack on the rear axle to handle. @D.phantom The R32 GTR manual actually has more than I give credit for talking about the non-HICAS cars: You can probe the pins on the diagnostic connector directly to read the EPS solenoid voltage as far as I can tell following the flow chart.

      Hi all, so I bought a very low kms 2019 Q60s in Nov 2022 and have been driving it stock for 17 months. The power from the VR30DETT has been a little scary as these cars did not come with a LSD. Although the ECU does well with compensating the lack of LSD by using automatic braking on different wheels when there is lost of traction etc, it does not really give me much confidence to push the car harder. Further to that, the car feels quite boaty especially around sharper corners or roundabouts - it would seem like the wheels are lifting on one side. These engines are also very prone to heat soak as the heat exchanger is tiny. I felt this during the heat wave in WA over summer even in normal driving. Gear shifting in the Q60 is also something that I hated - it's quite harsh at low speeds especially in traffic.  I recently purchased a set of f&r sway bars, rear diff brace and a heat exchanger from Z1 in US. Here are my thoughts 1) Rear diff brace - no more wheel hop when accelerating quickly. wheel spin still present but manageable comparing to before. Gear shifts are now smoother, you can still tell its shifting etc but you dont feel the harshness. I would highly recommend this mod, and it should still be on sale at Z1 at the moment. 2) Sway bar - there are 2 settings for this F - 114%/165% increase in stiffness over stock and R - 138%/214% increase in stiffness over stock. Currently I am on the stiffer settings. The car feels very planted. Due to the weather over here I have not been able to test if i need to reduce the stiffness. So far it's much more comfortable to drive over stock as you dont feel like your car is lifting up and in fast turns you can control the car a lot better while turning left and right in quick succession.  3) HX - the Z1 HX has a much higher capacity and surface area (up to 200% or something). Again with the cooler weather it's a little hard to tell. I went with the Z1 HX due to the price, size and colour (black). You can't see the HX through the front bumper. There is a cheaper brand but it was smaller and the rest were more expensive which i didnt think was worth the extra since I won't track this car much at all. All 3 mods were easy to install, all plug and play. Note of caution, the front bar needed to come off for the HX to be installed.

      A is the HICAS CU.  As far as I know, there are no other modules located at A in a car with HICAS, so it is fair to presume that F is the variable power steer module for non-HICAS cars. Same location, give or take. Makes sense - the wiring loom for the HICAS cars has the speed signal, power, solenoid drive, etc wires all present there - so why move the module and have to upend the wiring loom?   Having said the above though, it may be the case that F is further down in the rear guard - it's hard to tell. In which case it may be something else. Yes, it is the multi-pin plug next to the under dash fuse box. Top left corner. Can't miss it. Be very careful though - use insulated probes to poke around in there so  you don't accidentally short 12v to ground or an ECU input etc etc.

      They didn't. This is their comments; I'm not sure why they don't have the OEM specs.
