However, I`ve been in a lot of road cars that have made brake upgrades, and they`ve ALL pulled them a lot harder (including my dad`s old Monaro upgraded to huge AP Racing brakes). I know some brake experts aren`t fans of some of the Wilwood transmissions as they have a seat bending compared to the more expensive AP/Alcon transmission, but it depends on what you do with the car. As for the insurance issue, the insurance company would have to prove that the accident you were involved in was a direct cause of your brakes not legally/approved/designed/not having dust boots or whatever the exact reason for all this Wilwood legality. The only way I can see this is if your brakes fail as a direct result of the Wilwoods and you couldn`t stop the car and it crashed into another car. When have you ever heard of something like this? Calling the brand cheap and dangerous is a complete bull. Many people have «cheap» Taiwanese/Chinese brakes and even these don`t cause any problems. May I ask where all the talk about «no dust seals = illegal» comes from? www.skylinesaustralia.com/forums/topic/350163-wilwood-big-front-brake-kit-group-buy/ You should buy my brakes. This is how you can finance my willow woods. I have never seen a picture of these brakes to do justice to the first Commodores. Obviously, these are not certified like some other packages? If you drive a race car or plan heavy use on the track, you should spend more money on such brakes.

Righteo, so I talked to my engineer and he doesn`t see a problem with modifying the brakes as long as everything is installed properly and passes the tests he needs to do (pretty much what Roy said). I think the whole «certified» issue is a bit misleading. Many cars drive with Wilwood brakes on the streets of Aus, completely legal. I mean, I drive a 454ci, in an RV, Willwood brakes (no dust seals), various trans, suspension, fuel tank blah blah, all completely legal. First I had to convince the engineer that all the changes were well thought out and well executed, then I had to pass dynamic tests, emissions, etc. My engineer (I think like many others) cared more about how the car worked as a whole than just one element of it. The guys remember that Wilwood has been making brakes in their California factory for about 35 years and also makes many brakes for the U.S. Army. These are not cheap and dangerous brakes.

FYI, fastbrakes.com just released AP racing saddle kits for less than $2,000. The main problem is dust boots and the fact that they are not legal in Australia (but really, who will know?). Obviously, they are not ADR approved, that`s pretty much obvious. Nor do most of the Jap brand brakes. I hate to ask a stupid question, but what exactly will these brakes have on standard GTS-T brakes with decent pads and discs? I find that the few times I can`t stop fast enough, it`s because the wheels are locked, not because of the fame of the brakes, so it`s more of a traction problem than a braking problem. I haven`t been on track yet, so I never felt like the brake was coming off. I guess these are only useful on a race car, right? I`m not sure about the other states, but my engineer here in South Africa had no problem with them. On my (RV) I used the 2004 GTO (VZ) setup there. 6 pistons at the front, 4 pistons at the rear, these are excellent brakes. So if people who like brakes want to make sure everything is legitimate, talk to an engineer to get them modded (or a certificate or whatever non-QLD states do). It`s almost certain that this is a requirement for any brake caliper upgrade, so it`s nothing specific to these brakes.

I understand that most mods are illegal, but if you were to have an accident, the insurance company wouldn`t automatically check the brakes and be approved, you`d be a little, right? I haven`t had an accident and that`s just a guess, so I`m not really sure. Please keep us updated with the technical friend you have and what he thinks and how much they are approved, also PM sent to I`ve never heard of a legality issue on dust boots, and hard to see an engineer disagreeing with me. www.rodshop.com.au/holden/hd-hr-holden-wilwood-280mm-4-piston-disc-brake-conversion-for-disc-brake-stub-axles-1562.html GUY, I was about to buy a set of these Willwood brakes myself, so I contacted Hopper`s Stopper in Melbourne and Race Brake`s to ask if these brakes are legal in Australia because they have to meet a certain industry standard and ours are much more difficult than in the US, and that`s what I picked up. Ignore the fact that many people have done the wrong thing and drive with cheap and dangerous brakes. What I mean is being legal without an engineering certificate. Some kits, when I searched a long time ago, came with permission. Yes, I`m always looking for good brakes, not like the VT double brake. As for the Wilwood and Strange brakes, I`m not a fan at all and from what I`ve heard, most Australian engineers aren`t either. There are several reasons for this. These calipers have never been ADR homologated as they have not been homologated on any Australian car.
