Now: R32 Gtr Brake Upgrade Discussion

[Duncan]

yeah exactly.

brakes only slow you down.

[PSI_GTSII]

Well, went to check out the brakes and pricing etc today....and was a little bit more than I thought!

First up you cannot get DBA5000 rotors for the Standard 296mm R32 GTR, so it looks like (If I can cover the cost thru work) I'll be going for the 355mm DBA 5000 Discs's with either Brembo or AP Racing Calipers, with Braided lines, fluid and pads it retails for $10400 for the AP Racing or $9800 for the Brembos....

Has anyone tried the G4 330 mm kit and i know its made in some where else land but does it work. think the price was 2300 or near that

[sav man]

i just got the 355mm dba 5000 disks to go with my porsche calipers. There ment to be for a Coon GT , I just need to get some shims made up as the coon has a bigger centre bore than the skyline, and a 5mm spacer.

$10400 is heaps, that would be for all 4?

My Porsche setup is looking to cost ~$3900 for the front, and i'm leaving the rears.

Yeah thats for all 4, and is retail price, i wont be buying them so they'll be somewhat cheaper @ Trade price.

FTR the guy at the brake place says the Brembos and AP Calipers are similar in Performance but the Brembos offer more W*nk value....?....Never really thought of them like that but as there so similarly priced I prefer the Brembos only because the GTRs came with Brembos.

The 330mm G4 8 Piston Brakes sold by Just Jap for $2499 including Pads brackets and braided lines does seem like good value indeed

[PSI_GTSII]

Ok going down to order these brakes.

So of the 2 Brake options shown above (AP Racing or Brembo) whats the general consensus on which is best, i'm leaning towards the Brembos purely to keep with the factory theme, but am not really fussed either way.

Which do you guys reckon is the way to go...?

Also the bloke down there wants to buy my old Cross drilled 296mm discs and factory calipers...what do you reckon they are worth as I have no idea!...?

Cheers

I once drove a 33 gtr with that AP set up on the front and nearly creamed myself, I loved them!

AP is just as much a reputable brand as Brembo!

I think you need to upgrade the master cylinder on 32 gtr's when you have bigger callipers don't you?

Go round the corners faster and you don’t need to waste that sort of money on braking hardware. Spend the money on suspension and circuit driver training and I bet you do faster lap times.

cheers

[Beer Baron]

well on my 32 GTR I have the following:

DBA 4000 series rotoros front and rear

Endless Carbon/ceramic CC-R pads front and rear

cusco master cylinder brace

nismo braided lines

motul RBF600 fluid

cut off the front stone guards

and i'm still not completely happy. running on yokohama A048 semis on 17X9 inch rims.

not sure what i'll do next.

Could'nt agree more

I have just bought some Semi Slicks, will concentrate on suspension next.....brakes are costing me nothing, work is paying (salarys sh*t so have to have perks!)

Ended up getting the Brembo's, they are slightly cheaper than the AP and the disk size was bigger 355mm vs 343mm although the AP Caliper is a 6 piston jobbie, and the Brembo only a 4, there is also a 3 week wait to import either of them.

[GTRsean]

The ap calipers don't have piston dust seals so are not suited to street driving.

not true - CP5555 are a road caliper and have dust seals... http://www.apracing.com/roadcar/caliper/da...p?family=CP5555

what is the thickness on the rotor on the brembo kit?

it's not all diameter... my APs are 355x36mm - most 355 i've found are 32mm thick

that extra mass (should) make a difference as you've got greater heat capacity

I made this thread awhile ago and got alot of comments back from the guys in the know. Have a read through it as its got alot of great advice

That was a good read thankyou

Alot of you guys are very serious about your brakes and suspension setups!

So in summary, for an R32 GTR that is to be street driven, has under 250rwKWs, and is occasionally to be used in short Hillclimbs, Club style Track days against the clock and Motorkhanas

(And i'm Guessing the majority of 32 GTR owners fall into this catagory)

The best brake upgrade would be:

Motul RBF600 fluid

DBA4000 replacement rotors

(Retaining original Calipers)

Ferado DS2500 pads

[r33_racer]

We found alcons to be the dux nuts on our r33 Cost less then those two kits you listed.

[phunky_monkey]

If your replacing your discs I'd also get a caliper extension bracket and run 343mm front rotors with your stock discs. For the sake of $220 why not.

[GTRgeoff]

Some detail that a lot of people forget....oh and I recommend you look into RS73s group but for RDA discs.

Car & Driver did a test a few years ago ...Test Car was a WRX (US Spec which only uses two piston sliding caliper, not as good as Nissan 4 spot or later Model WRX 4 pots)

So tested kits were, std car, std car with upgraded pads and fluid, Brembo F50 Kit, Brembo Lotus Kit (Similar to as fitted to GTRs, 44/38mm pistons), Stoptech it and Prodrive Kit (Alcon)

Stopping Distances 70mph - 0 , 3 Stop

Brembo F50;_____________ 185 / 183 (Average / Best)

Brembo Lotus; ______________ 200 / 196

Prodrive; __________________ 198 / 194

StopTech;__________________ 187 / 186

Stock; ____________________ 205 / 196

Stck with pads and fluid; ____187 / 184

The above figures are all in feet, one stop difference between pad and fluid upgrade to crappy sliding caliper brake setup and massive Brembos is 1 ft...lol 30cms:( And over 3 stops the average is 2 ft...lol 60cms:)

So you can see the one stop max of the upgraded pads and fluid is damn good when you consider the $$$ to % difference.

Stopping Distances 100mph - 0 , 25 Stop

Brembo F50; _____________ 299 / 288 (Average / Best)

Brembo Lotus; ______________305 / 294

Prodrive; __________________ 308 / 295

StopTech;__________________ 297 / 290

Stock;_____________________ 340/317

Stck with pads and fluid;_____316/299

Not the world of difference you would be led to believe by the "you need 6pot caliper 343mm rotor crowd."

Brembo F50;.................15.8......................... .13.1 / 1.3

Brembo Lotus;..............12.9.......................... 12.9 / 1.1
