So.. trying to find someone reliable/affordable to machine dogbones etc. for my V8 Supercar alcons is proving to be a bit challenging. (My calipers https://fbcdn-sphotos-d-a.akamaihd.net/hphotos-ak-ash4/1094662_10153125748100301_2119536866_o.jpg )

The Alcon extremes (http://www.jdl-brakes.com/alcon-adv-extreme-brake-kit-front-6-pot-o365x32-nissan-skyline-r32-r33-r34-gtr.html) appear to be a much easier upgrade as they come with all the parts ready to install.

Aside from running a smaller rotor, what are the main differences between this kit and the calipers I already own?

Brakes are for a 32 GTR track car, mainly doing sprints.

Well the kit you have allows you to run a bigger rotor with better wheel clearance. It is lighter than the Advantage caliper. But those things are all bee's d1ck things. The one main reason why your calipers are superior is the titanium pistons work waaay better at keeping the heat from the pad out of the brake fluid.

But again, the Advantage kit is pretty damn competent on most track GTRs. Especially if you are going to get stung for $600 for a pair of radial mounts. $800-1000 for the hats and bobbins to work with the V8 Supercar rotor...then lines and pads. Buying $1500 calipers can quickly add up to serious money if you dont have a line on good combination rotors and hats.

If you are going to run those calipers I personally would go brab some off the shelf 380x35mm rotors, either aftermarket or off an R35 and then just pay the money for the radial mounts

Lug mount, is your traditional mounting style that comes standard. Radial mount calipers differ, in that the caliper bolts go through the top of the caliper to the upright. It's regarded as the better, stiffer way to mount the calipers. You can get radial mount dogbones.

So if I run R35 rotors I don't need custom top hats & bobbins?

Is a radial mount the same thing as a dogbone? Who does them for $600?

You can run whatever hat/rotor combination you like but Troys point is that the replacement cost of the rotor (or hat and rotor) is one of the big considerations in its selection. By using a part from a certain vehicle (eg R35) you are getting a component that will be made by a number of different manufacturers which will help keep the price down. Eg Project Mu 324x30 hatted rotor is thereabout of a grand. The 345x32 is double that. The other cost consideration is the price of a pad. same story there. Buy an orphan pattern and you will get screwed every time you need pads.

Yes a dogbone and a radial mount are, essentially the same thing. A radial mount uses bolts that align radially to bolt up the calliper, a dogbone has locating bolts at 90 degrees to that - hence the same as it looks a bit like a dogbone. You need to find a machine shop and give them some drawings. I have tried and utterly failed to find someone for this sort of thing. But this is a one off cost, not a recurring one.

I use Alcon front and rear kit for one year on my R34 GTR. So far 12 track events, and these brakes are best mods I've ever done.

Some 17s ... not all 17s. Based on my experience with 343mm setup and CSC calipers, AP CP5555 and F40/50 calipers and 343mm rotors thinhs like AVS Model 6, Work XD9s, 57 Gram Lights, CE28s etc wont fit inside 17" wheels. Teh CE28s fitted but not enough clearance

Things like Weds, LM GT4s, TE37s etc will do it easy. I have not tried them but people seem to enjoy some luck with Enkei RP-F1s etc

If you want to guarantee fitment inside a 17" wheel then you need to go 332mm rotor

Have just ordered RS 19's for the front for the advantage calipers on a R33 GTR. Will report back.... Anything would be better than the 2500's.

Did you mean DS2500 or DS Performance ? I thought they come with DS Performance http://www.jdl-brakes.com/special-offer-alcon-adv-extreme-brake-kit-front-and-rear-nissan-skyline-r32-r33-r34-gtr.html

DS Performance pads are better than I thought. When mine kit came, I was ready to put RS29 for first use, but my mechanic put original pads ( DS-P ) by mistake. I can say, for normal street use, they are not bad. I haven't tested them on track, but if someone use car on street only, DS Performance are not bad choice.

I heard that Alcon kits what we buy, are street legal in Europe, that's why they come with street legal pads.

You could be right.

Either way, the pads that the kit comes with are junk.

    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.
