hey,  

considering upgrading the brakes of the r30 before i  

get in certed. has anyone done this upgrade, could they

tell me what parts are involved?

ive heard i need r31 front struts not sure on what else

is needed?

cheers

DONT BOTHER WITH HR31 BRAKES.

THERE A 2 CHOICES AVALABLE:

ABS HR31 HUBS AND RE-DRILLED S14 ETC DISCS WITH R32 TYPE M CALIPERS;26MMDISC

OR USING YOUR EXISTING DISCS AND MACHINING OF THE DISC TO MAKE IT A HUB

AND USING A CUSTOM 330MM COMMODORE DISC WITH GTR OR Z32 CALIPERS 32MMDISC. FALCON 1/2 INCH WHEEL STUDS :LONG:

WITH 10MM SPACERS FOR THE CALIPERS ITS ABIT HARD TO EXPLAIN.

I USED THE SECOND OPTION IN MY DR30 :RB26 440HP ATW R34 GTT BOX:

IT COST ME ABOUT 1200 FOR THE DISCS AND CALIPER SPACES AND LABOUR FROM SBC IN ST MARYS. NEVER HAD A PROBLEM WITH FRONT BRAKES AFTER THAT.

REAR DISCS A PROBLEM RED HOT AND CRACK IN HALF.

THIS IS IF U WANT TO RETAIN 4 STUD.

I HAVE THE WHOLE SET UP FOR SALE. PITY ABOUT DIFERANT COUNTRIES

how did you adapt the coilovers? dont they use a diffrent mounting system  ?

what you need is s-13 coilovers and s-13 hubs, there the key, the rotors from the r33 n/a version are 4 stud or you re-drill r32 rotors (which i did) put it all together. this is as far as i've gotten, if you want to to be more correct you can get a set of r31 adj camber tops or just turn around the s-13 tops to fit...cost so far about 1100. might spend all this weekend trying to fit it all, the only thing stopping me is i only have 15" rims on the hr at the moment and i'd need 16s to fit over the r32 rotors and callipars!

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Yes I can see how that would put you off HFM, especially with the price of good quality brake fluid. From what I understand it as you say the BM50 is the standard BMC for a R32 GTR, I must admit I would like to go far a Genuine Nissan BM57, but lack of cash prevents that at present. With the price being so close between the genuine BM50 and BM57 a BM57 New it seems a better choice as you gain that 1/16 bore size with the BM57, I would be interested in how much difference you feel with the BM57 fitted. I am going to take SteveL's advice in the short term and see how much actually comes out of that proportioning valve vent and save up for the Genuine Nissan part. Thanks for clarifying the HFM failure

      Thanks mate. I just got the post inspection 1/2 done from state roads when the starter motor packed up, either that or the car alarm system is having trouble.  OEM part number 23300-AA112.

      Starter motor replacment teeth count.

      By oHBoy. · Posted

      Hi, I though I was coming to an end in finding a replacement starter motor for a rb25de neo. I came across a starter motor from Taarks and a message below stating: Direct fit. 11 Tooth count. All below part numbers have been superseded to 11 teeth. Can some body shed some light on going from 8 teeth to 11 teeth apart from 36-month / 25,000 km warranty for passenger vehicles to 12 Month Warranty. Compatible with the following Nissan part numbers: 23300-20P00 23300-20P01 23300-20P05 23300-20P10 23300-20P11 23300-AA111 23300-AA112 23300-AA300 23300-08U10 23300-08U11 23300-08U15

      J50 clock date suddenly reset to January 1

      Low battery? Maybe check capacity? I know first-hand, on BMWs if your battery drops below 80% capacity, it starts causing strange issues.

      Wheel Sizes & Offsets For Skylines

      8.5 +37 = should fit rear, but I think it'll hit on front. What you want is low 30s/high 20's front, mid 30's rear. That 17" screenshot you posted looks good, I'd run it on my R32 (but that's long dead now). For tyre sizes, my rule of thumb is: 8': 235, 9": 255. But that's just my opinion. Nismo sizes: 18x8.5+35/18x9.5+38 is a good starting point.
