Which Big Brake Kit

[R.3.2.G.T.R]

i would have taken this up as well if i could get the calipers to clear my wheels, very good pricing

have settled for the D2 group buy kit which seems to be priced very well and has good reviews

[Risking]

I forgot about the ducting photos.

These two arent from an australian supercar they are from a current Newzealand V8 touring car.

They run a controlled Wilwood calliper and controlled brake duct.

Our local supercars use an almost identical ducting setup thats kevlar.

[Risking]

The small hose running into the top of the duct is connected to a water jet that sprays like a garden sprinkler into the ducting.

Hi sorry if I might be hijacking your thread, but this seems to be the best place to ask.

I drive a 99 R34 25GT, at the moment it's a daily driver but it's also a long term project car (Engine won't really be touched until I get myself another car for a daily driver).

I've taken it on one track day so far and I'm looking at taking it on the track a couple of times a year if that, nothing too crazy.

But I'm looking at upgrading my brakes with a big brake kit. I was looking at the D2 kits but I'm not sure what I should be getting. Can someone please give me a couple of options on what to get? I'm not sure on rotor sizes either. I'm hopefully getting TE37s soon also so they would have to fit under those..

Thanks for any help in advance

So is the air and water vapour mixture just directed onto the face of the rotor on that side?

The 330mm D2 kit is the safe bet, they will fit under most 17s. If you want the 355 you will need 18s, the TE37 design is great for caliper clearance and should not be an issue. Really, the question should be what size tyres do you want to run (17s are much cheaper than 18s) then choose the wheel, then choose the larger or smaller brakes to suit. Either kit will be fine unless you use the brakes more than you need to

Brad, we need pics of the other side of the rotor...I'm willing to bet the vent runs to the centre of the disc not the outside face, but that's not how it looks in those pics

[Risking]

Spot on the money. There is a properly made up funnel that crates a neat shape that suit the inside of the rotor.

Jacking up a supercar now to take photo of it.

here is a couple from both sides of a VY taxi.

This car has a front mounted rack unlike the previous car that was rear mounted.

The ducts on this one are mounted at the front of the upright obviously.

The NZ VY has a very similar thing but smaller.

There is a carbon peice that locates onto the duct which adapts into a 3inch spiral tube to allow the flex before entering very similar kevlar ducting to the front bar.

The kevlar parts from that VY are removed at the moment and being repaired.

lots of space when there is no driveshaft going to the hub eh? Interesting the shape of that final duct, I bet they have done a lot of testing about how much air to aim directly at which part of the disc vs how much to direct at the centre

[Risking]

Real race cars only have two drive shafts Duncan

I wouldn't want to change the ducts that's for sure. That car has done 3 Bathurst 1000 events and finished all 3 times as well as sandown enduros so if say they did something right.

The differences between teams is interesting to look at though.

A lot of the time they run the cars with the ducting blocked off at the bumper.

I see said the blind man! Great job Brad, thanks mate.

No kidding with space due to no driveshafts!!!

[Risking]

Front drive shafts are overrated!

For a car with a live axle arse end they certainly work well.

Anyone wants Alcon rear kit ? SInce they offer free shipping for rear kit, I will order it, and will keep it for spares, but I thought if anyone wants rear too we can drop price little bit http://www.jdl-brakes.com/alcon-adv-extreme-brake-kit-rear-4-pot-o350x28-nissan-skyline-r32-r33-r34-gtr.html

Has anyone used brake ducts as they sell http://www.jdl-brakes.com/nissan-skyline-r32-r33-r34-gt-r.html ?

I got mine Alcons from JDL, great service and stuff

These seem to be pretty cheap http://www.ebay.com.au/itm/330mm-Wilwood-Grooved-big-brake-kit-200sx-300zx-skyline-200-sx-Brembo-Discs-/200809498851?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2ec12dc8e3

Does anyone have experience with them?

I bought my first R32 GTR with Wilwood 330 mm kit on it. It was good, but not better than Brembo from R34 which I fitted few months later. Maybe I had some issue with pads from this kit, and that's why it didn't perform as it should. Anyway, I wasn't happy. It's still my #1 http://www.jdl-brakes.com/special-offer-alcon-adv-extreme-brake-kit-front-and-rear-nissan-skyline-r32-r33-r34-gtr.html

Those wilwoods are a very average setup overall.

The callipers have a terrible open bridge design and they flex horribly. The lug mounts they use also flex a lot if you dont have the callipers spot on centred to the rotor.

I've used them on lighter road cars like MX5's and pulsars in the past with little problems

I fitted a set up to a Toyota 86 a fortnight ago only to remove them after a track day and change over to an AP calliper. The pedal feel was horrendous at 3 corners at Wakefield park.

AP's being tested on Wednesday but already on the road they feel so much nicer under firm braking.

I have Alcon front kit with 343 mm rotors, but thinking about these kits http://www.jdl-brakes.com/special-offer-alcon-adv-extreme-brake-kit-front-and-rear-nissan-skyline-r32-r33-r34-gtr.html What wheel do I need to clear 6 pistons calipers with 365 mm rotors ? 18x9 +15 would be ok ?
