Big Brake Kit For R32 Gtr

[Roy]

They are the bad boys. They are not as pretty as some of the other calipers kicking around these days, but they are still the title holders for best all round caliper.

They can saddle a slightly bigger rotor, i have seen them used with 382mm rotors. Expect to pay about $1300 per caliper, and then hunt down the supplier of rotor you want to use and get some custom hats machined up. ($500 each covers it) The 36mm thick rotor helps a hell of a lot with cooling.

For example up until around 2002 V8 Supercars used 355 x 36mm rotors for 650hp and 1350kgs. After around 2002 they went 376 x 36mm rotors. They run slicks slightly less weight and more power in a race car. So something similar in a tad heavier car with simlar hp would be enough for what most of us do with cars......well IMHO

thx roy, chasing it up now, for the rear, just the normal 4 piston ap upgrade kit should do with the 330x24 rotors?

edit- ok just got off the phone to a few places, can get calipers $1200 each and rotors for $650 each, 375mm x 36mm then id have to haev the hats and brackets machined up...

any suggestions on rotors? or will AP do the trick? the guy i spoke to said he supplies the same 375x36 to some v8 supercar teams.... i dont kno much haha just goin on wat he was saying

In my opinion that is your best bet. These days V8 Supercars run a control rotor Alcon rotor, but in the pat teams either used AP, Brembo, Alcon or Performance Friction. So there are plenty of people that make that dimension rotor. Shop aroudn and find the best price and avaialability and go for that brand. You will find that they all run different pcd so once you decide on a brand of rotor you will have to stick with it which means your custom hats will be specific to that rotor.

But hats and brackets are not rocket science and plenty of good brake shops or motorsport engineering places will be able to do them for you. The scariest prices i have ever hear for hats was $600 each and brackets $400 each. I commonly get them done for more like $600 per pair of hats and $400 per pair of brackets (ballpark figures to calculate)

But am interested where you are able to get the AP CP5555 for $1200, thats a great price. Cheapest i have ever been able to source them is $1350 each and that was importing them

I could scare you easy then Troy. My latest brake adapters and hats cost heaps more than this. However top shelf custom stuff, using 7000 series alloy to make radial mount big radial mount rack off adapters, with pockets machined to save around 100 grams per adapter. Hats same material and pockets machine to waste donw where strength not needed, for further weight saving, then all hard annodised. With special floating hat nuts and bolts etc and one off set for programming and machiningetc many thousands.

Pic below is my old 997 Cup brake adapters, compared to new AP Racing Sprint V8 Supercar caliper adapters with pockets machined.

Also R35 GTR brakes are big but not very good as heavy and no cooling.

LOL, thats why i rate you John, always playing with the gear i can only dream of. I am betting those GT APs are mega light as well.

Yep Bris fraction under 2.5kg per side lighter than the 997 cup package. Rotors are 375mm 48 vane 55mm anulas ( swept area of rotor ) 997 380mm 72 vane 65mm anulas. I don't do endurance racing and have good cooling, so this set up is going to be better. Callipers are billet alloy and wasted down to minimum weight, compared to cast alloy 997, which are slightly bigger and use a much bigger pad. I have not tried it yet but 5kg less un sprung weight whould be much better.

John when are you going to offer us a kit based on correctly drilled and centre-hub sized Falcon GT-P 355mm x 32mm discs and adapters so we can throw on a set of cheap as chips F40/F50 Brembo calipers all the Ford boys are offloading from their barges. Those GT-P units have near identical offset to the stock Brembo disc.

Surely DBA / RDA would listen to you and do us a batch of rotors.

best way to go about it is adapting v8 super car brakes. they run 17's but not your normal ones....

things you need to look for are pad availability, and pad thickness. anything taking less than 25mm thick pads is a waste on a race car in my opinion. also thick rotors 32mm isnt gonna last. 35 and 36mm thick is the norm these days.

for comparisons, i got my 355x35 pfc direct drive rotors for about 650 each. where as a brand new ap supercar rotors at 375x35 were only 510 each lol....

but i can get my pads of ebay ex-nascar for $100 a set of brand new bedded pads, where as the supercar pads are about 800 a set brand new.. hats wherever you go will be on average 500 each for a floater with anadising regardless of what size disc..

anyone know off any brembo front supercar calipers for sale?

ps jhon, that looks very much like bosenjack's work

Correct top shelf quality too.

My rotors are the cheap part brand new Alcon pre bedded 48 vane cresent slot way less than those PFC or V8 Supercar current model as old stock and no one uses anymore, suits me.

Yes talking to fats about a quality cheap brake set up how about Brembo Big mono bloc 996 GT3 cup 6 piston callipers, 365mm by 32mm slotted rotors 48 curved vane, annodised alloy hat and adapters, pads, braided lines etc for $4300 the lot. Requireat least 5 sets to be worth while.

lol, reading this thread reminds why I ditched the GTR and love my GTS-t and it's GTR hand-me-downs

Cheap is funerer

Sounds good but too much brake and $ for most weekend warriors with 300 rwkw or so. How about correctly dimensioned DBA 4/5000 discs for $1k and brackets for $400/pair and we source our own F50 calipers for $1k; total $2400. You could even produce a thin 1 piece plate that rides on the GTR hub and combines as a spacer for the different stud diam 12 vs 14mm) and the different hub diameter, or provide individual spacers in the kit.

I reckon scooby is on to something there....you'd sell 10 sets of those for every one of the top line kits...

better remind him he has to stick to standard size discs 324x32.....

apart from my own self-serving reasons for wanting someone to make a kit like this i reckon they'd sell ok and i don't know why someone with the right contacts hasn't done it yet. hell most of us would even get away with 355mm RDA solid rotors.
