i would be careful about the protective cover. i no its a good cooling mod. but is removing it for 1-2 weeks before it is damaged worth the $800 replacement fee.

-i learnt the hard way :spank:

I wouldn't worry about it. I have run without the cover for about 3 years. even went off backwards at EC over the ripple strip and through the sand (rock) trap at about 160kph and no damage except my cooling duct (like giants but alloy) got bent into the rotor. which didn't damage anything except the cooling duct. I just ripped it off and all was ok :w00t:

giant, do you know the part number for those pupies, and how much were they?

What did you damage? I have ran no shields for over 6 years...i lived at Windsor so plenty of dirty/gravel roads out there. I have spun my car at Wakefield and EC more then most would think humanly possible....and no dramas ever on my car.

In fact my only trouble has been at DECA doing motorkhanas on not so great surfaces where little pebbles have actually got caught between the rear rotor and the dust shields that i have not removed...so when i could be bothered i mean to rip them off as well.

So, interested to hear your experiences

yeah I vote something is wrong with the install... I run similar tyres with the DS2500's and some RDA rotors on my GTSt, and I can do about 7-10 flying laps before I seem to get any brake issues (soft pedal) and my rotors certainly don't look like the pic posted... oh I still have the dust shields on too but I think Roy has just convinced me to ditch them... UAS do alloy brake air diversion ducts for GTR/GTSt's BTW, look just like the pic Giant posted

I couldn't see how to unbolt mine, so I cut them off! (Well Chris did, i just cheered).

Nick: You're in a gtst, bit lighter than a GTR... most gtst boys don't seem to have too much trouble with brakes. Bastards.

i made the mistake of driving thru road works, next to newly laid bituman. i had shit fling up, chip the disks, and actually got cemented on. had no choice but to replace all 4.

but that is wat u get when u drive over crap, if your careful you could be ok.

Yeah would rather unbolt them than cut as it gives the option of putting them back on when/if required

guess I will just have to see how hard it is to get them off myself

bit worried it might effect hub spacing or something though will have to cut em if this is the case

found a pic

you can see the guides at the bottom of the photo

cheers russ

Nice job of fitting the dry sump in there!

I did the same thing with a piece of 75mm ducting hose and ran it along the castor arm and had the intake right below the bearing on the end of the castor arm.

they can be unbolted but almost everthing has to come off first

the rears include a mounting nut or bolt? for the handbrake cables and pads so you probably

would be better off cutting the rears and leaving the innner section still connected

Setup: R32 GTR, UAS 324mm rotor upgrade, DS2500s, Motul 600, rebuilt calipers

Here's what they look like after a track session;

Looks to me like the pad isn't even making contact with the inside of the rotor, it's still rusty! (and I can see the lip where the disc surface stops).

99% of the problem is going to be your calipers aren't square with the discs. That's why you're blueing the outside of the rotor so much.

^^^hmm shouldn't you be using a larger pad? So that the pad makes use of the entire available disc surface?

I've done the 324mm upgrade on my gts-t and i'm using a bigger pad (had to machine the ends off it to get it to fit) but it makes use of the whole surface of the disc...

Looks to me like the pad isn't even making contact with the inside of the rotor, it's still rusty! (and I can see the lip where the disc surface stops).

That's normal with using the sumitomo calipers (from the 296mm rotor) with the larger 324mm rotor. If i got the brembos the pad would wipe the whole face.

I would be worried about the moving the radial centerline of the pad away from the centerline of the pistons (i know i'm not describing that well) as this would place uneven force on the top of the pistons. They're designed to generate force and move in a single dimension, so i dont know if they'd cope well in the long term. Again brembos are the best solution for that IMO.

Anyway i couldnt see any issues with the fitment, so i've removed the calipers, sanded the mating surfaces to marginally change the angle of the caliper and refitted. Now i need to find time for tie-rods + alignment then wakie again for another thrash. I'll take the DS3000s with me and swap them over if i have any more problems.

Thanks everyone.

    • 9" wheels are a little too wide for a RWD 32. They can fit. People have put R33 GTR wheels on 32s for years and years. But they are a very tight squeeze. This has been known for about 30 years. As I said - there is no difference between a 17 and an 18 in terms of what will fit. The rolling diameter needs to stay about the same as stock - not very much larger. If you increase that, you will start to have problems. If you increae rolling diamater at the same time as yo increase width, you will have problems earlier. as 9" wheels are pushing the boundaries already, you would need to be careful with tyre choice. I would put 8.5s on the front of mine, but would expect problems with 9s.

    • Diagnostic flow for a code 21 says check signal at the ECU pins, on a voltmeter of some kind it should read 0.1V at idle, 0.12V cranking, 0.15-0.25V at 2000 rpm. Check each coil such that +1, -3 is infinite or very high resistance, -3, +2 should do the same. (-1, +3), (+3, -2), (+1, -2), and (-1, +2) should all be somewhere between 0 ohms and high resistance. If you trace the path from the coil pin all the way back to the ECU in the diagram the resistance you measure at the coil vs connected to the harness should be pretty much the same. 
    • I have an elite 2500 running an adapter harness on an rb25de neo r34. I took the butterfly out and removed all that junk. But I also went Plus+t at the same time. The butterfly thing works in reverse to the boost solenoid on the Gtt if that makes sense
    • yeh they are 235/45/17 up front and 255/40/17 in the rears. I still didn't get my answer if i can fit a 18x9 up front. I want to get 4 of this and see if they will fit before committing as they didn't see an 18x8 as an option but there is a 18x9.5 also.   Enkei RS05-RR 18x9 35mm ET 5x114.3 75.0 Bore Matte Gunmetal Wheel
