D2 Racing brakes

whats non Chinese about Taiwan, Republic of China?

Hey Zap, I have to agree with a lot of things that you had say regarding compliance; but there are a lot of xr6t owners pumping 300-400RWKw running std brakes. This would have to be way above the ADR limits of testing and no manufacturer would meet compliance.

that's not really how the ADRs work. The standards they test to are based on speeds (up to 180km/h) so if you are stock or have 400kw it doesnt matter you can still reach those speeds. Some engineers might make you do an upgrade but that's their discretion in most modern cars not the ADRs. Its different in something like an RX3 that would never have seen those speeds standard but will with a 13B so therefore needs an upgrade to meet standards but its got nothing to do with our cars.

Apart from Stopping are D2 brakes good for any thing?

Some interesting info in this thread, which makes me wonder...

Without looking up each states modified car guidlines, I belive you can fit Brembos from FPV, to a FPV car, as they were a factory option, but can you lawfully fit FPV Brembos to a non-FPV car, such as an XR6? Being that FPV and Ford are different vehicles?

The reason I wonder this is I recently spoke to an dealer, asking if they could spec up Brembos from the F6, onto the GE6T I was interested in... answer was no, the brembos have not been tested on the GE6T, so cant be lawfully done.

Anyone have any real info on this?

Yep and 2 local dealers in syd took deposits off me for a GTHO to but hey im still waiting on that count, dont belive everything they tell you. All falcons from XT through FPV's are the same car's, the only diffence is the cosmetics power out put and shocck/springs.

The factory brembo kits are legal as far as im aware as they are a factory fitted item. Ill find out tomorrow for sure and let you guys know.

There are several topics going all at the one time.

As far as fitting Brembos to a non brembo fitted model, it would be breaching it's ADR's, but you could get an engineer to sign off on it, as the brakes are approved for that use, and comply.

The problem with modifying your car is that technically EVERYTHING aside from factory parts are technically illegal.

As for the D2 brakes, I doubt that it would reduce the stopping distances at all. I have had this debate many times on this forum about upgraded calipers and stopping distances.

This is an example:

Your Falcon has stock brakes and can cause the ABS to activate when doing an single emergency stop from 80km/h.

Fitting Brembos/Alcon/AP/D2 will NOT shorten the stopping distance. Only fitting better tyres (and calipers) would make any difference.

However, doing the same stop 5 times is where the difference is noticable, as the larger surface of the pads will better dissapate the heat.

People have a missconception about what a big caliper does. The single best way to stop in a shorter distance is better tyres.

I have seen many times people with their D2's and Nankang tyres and they think they have the best braking setup around, when in fact they have actually reduced the braking performance (and increased the stopping distance) of the stock system. This is becasue of the crap tyres.

Go read the Vehicle Standards Bulletins, especially VSB 14 (NCOP5). Was told by the licencing center here in Perth that it contains everything you need to know about the legality of modifications done to your vehicle.

if that's aimed at me then with your engineering wisdom maybe you should explain how having 400kw makes it any harder to stop your car from any legal road speed compared to when it was standard

Zap - you missed one thing. It might not reduce stopping distance but the most beneficial thing to preventing accidents is not to drive like a

I was referring to my knowledge of engineering and Geography.

LOL, that's not how it works at all. The number one thing to do too reduce braking distances is upgraded pads with a higher coefficient of friction.

Your getting confused betwen friction and pressure. Small single piston brakes can apply enough pressure to lock a disc but it wont apply much friction.

Bigger calipers and therefore larger pads can apply a greater amount of friction at a low pressure and therefore not lock the rotor.

The larger rotor has two effects. Firstly it has a greater surface area which enables you to have a larger contact surface between the pad and the disc. Secondly it means that a greater rotational force will be applied to the wheel.

Fitting larger brakes, Brembos, Alcons etc, will absolutely reduce your braking distance. Even just better pads with a higher co-efficient has massive effect. Just changing pads from Bendix to QFM K750's reduced my braking distance by 50 meters into turn 1 at Sandown
