He pretty much summed it up.


I'll be honest, I just bothered reading a bit and saw the pictures..... in all honesty, those little waves will reduce contact area. People might think it's just a bit, but take into consideration the amount of contact area provided by an 11.5" rotor vs a BBK disc of about 13.5". The increase is massive. Those little "waves" seem to be a factor that just MIGHT reduce the extra surface area provided by the extra 2 inches of the bigger brake disc.


I can see the pros and cons just by looking at the design, but honestly, I believe the cons outweigh the pros on this.


For racing applications, modified discs have worked just fine up until today by using cross-drilling, vents (which are found in almost every modern car today), specials coatings, and using different materials.


For street applications, how many of you honestly drive so hard in the streets to cause the brakes to catch on fire? Before anyone gets clever, I am speaking realistically and legally. Race on the streets, and catch you brakes on fire, I'll laugh. But yeah, there's just no way to make the brake upgrade kits we can already buy overheat on the streets in a realistic scenario, unless you screwed up mounting them up and following protocol (brake fluid choice, materials, etc). Also, if you're using your weekend track car as a daily driver, here's what's done in your case: carry an extra set of brakes. 1 for every day, and swap it out at the track on the weekends.


So in summary:

CONS:
a) Sacrifices contact area to lose weight
cool.gif should cause uneven pad wear
c) Traps water wherever the hell it was that it got trapped, which is a horrible thing to happen, since those things need to maintain their shape to actually work. Warping on these things has to be fatal.
d) Might cause uneven pad wear
e) Probably more expensive to buy due to it's shape.
f) More expensive to maintain due to the latter.
g) and is probably cosmetically unappealing to the majority.

PROS:
a) Reduces weight by eliminating contact area
cool.gif Allegedly provides better cooling (I can actually imagine how it works, so I have no reason to doubt it, but I still question the method in terms of practicality).
c) Might be appealing to the minority (kids still like going against the majority, right?)

skip pass the patent part and he brakes it down and explains everything.



actually f**k it. I dont even know why I bother to post shit here anyway.

Nice updates to the thread...

The "wave" thing looks to be good for getting mud out of your brakes. I thought of a good application though:

True: When you're riding dirt bikes with friends and "leading" and there's a pile of horse dung in front of you, it's a lot of fun to not dodge it. If you clutch, over-rev, and release perfectly, you will spray your pal behind you with manure.

It keeps them off of your line.

Sometimes the eyeballs are right.

The physics behind off-road two-wheel braking vs. on-road four-wheel braking are immense. Wave might work in muddy conditions (and might not even be worth it then), but not on cars.

Nice to see that braking is important to some folks though.

braking will be alway important when you see a corner after going trough a straight at 150mph.
