6 Pot Brakes - Brake Bias Controller Question

Hi guys,

The brakes on my R32 GT-R have always been crap. The R33 GT-R Brembo upgrade is slightly better but they just don't deliver that punch that I'm looking for.

I've taken the plunge and bought 6 pot AP fronts and 4 pot AP rears (full kit with rotora, brackets, fluid etc.).

What I need to know id what else do I need? The kit comes complete with everything I need to get them onto the car but do I also need to get a stronger/larger/upgraded booster? And I am very curious about a brake bias adjuster for the cabin too. Any advice on that (what brand, where from?) would be greatly appreciated. Thanks in advance.

Justin, I don't think you need a brake bias controller, that brake package you've bought should have the right balance...

Have been wondering this myself does the booster need to be modded to run this kinda upgrade what about r33 brembos did u still run the same booster from the 32 or an r33 one? Do u wanna sell the brembos once u get the ap's on there, hint hint, might know someone who is interested.

i run 4 pot aps on the rear of mine 330mm

and f40 brembos on the front with 355mmon the front.

at just under 220km/h at wakfield after the kink it pulls up dead straight.

the fronts still get a much bigger work out. mand the rears just dont ware out lol.

i think youl be fine.

If you want brake bias adjustment you need a whole heap of other gear, brake balance bar/second master cylinder etc etc....way too much trouble.

If you find the rears are locking too early just put some less aggresive pads in there...but it sound like the balance should be OK anyway.

Out of interest, what does a set of 6 spot AP brakes retail for? more than the just jap 8 spots with 355mm rotors?

the main thing is that look look after the ol' beer baron with your old crappy, useless 33 GTR gear! I'll take it off your hands as a favour cause that's the kind of guy I am. :devil:

I think the kit you have sounds like it should be right as you are upgrading front and rear together.

I just put Porsche 6 pot's on the front of my car, and I think i need a bigger master cylinder, as the pedle is heap's longer now. So you might need to consider that.

Shouldn't do. AP know their stuff & don't go too large on piston area. Even the 6 pot CP5555 only list at 50.1cm2.

Just to add another me too response, I run 6 pot CSC's on the front and 2 pots on the rear and the car pulls up straight. The CSC's are pretty much an AP copy.

I have been running Pagid Blacks on the front and Hawk HPS on the rear with no problems.

You have a nice package there.

Regards

Andrew

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
