Kewl looking brakes...

I wonder how well they perform, or whether this is just a gimmiky shape...

look nasty imho, a bit to Halfords performance to me
can't see any advantage to having them in that shape,
bet people who brought neon will get excited about them though

all they do is munch brake pads, and having been in a car fitted with a set, i can safely say it isnt very good for your nerves when it sounds like a boeing 747 on full chat when the brake pedal is used under any sort of pressure

Says it all really doesn't it. I bet "Wayne" and "Gazza" will love them on their chavmobiles.

"Wavy" discs have been on bikes for years.
The advantages of the wave discs are:
• The wave form aids self-cleaning of disc and pad.
• Up to 150 grams lighter than original, reduced unsprung weight.
• Lighter disc = less gyroscopic effect = better handling.
• Strong braking action with good braking "feel".
• Even wear of pad.
• The upper disc loses more heat (larger surface)
• The outer "teeth" can expand (grow) outwards when hot, therefore not causing the disc to warp.
• The constant change of contact area between disc and pad reduces the "grabbing" effect.

For those who are a bit hard of thinking, 'kewl' was used in a sarcastic manner, hence not using the term 'cool'.
Some good points raised, but as far as them being 'novelty' surely there must be regulations regarding the manufacture of such important parts of a car, tests they must pass etc?
If they munch pads, does this mean greater friction and therefore greater stopping force?
They seem to be employing a similar shape to bike brakes as Rich said, so if it works on bikes, why not cars?
Im not saying they are great, just curious as I have never seen them before and wondered how effective they are.

Looks like they're trying to be drilled and grooved but only a few mm deep. Give it a few thousand miles and they'll look like normal plain discs with weird edges.
I would imagine they'll get much hotter than bike brakes as bikes weigh nothing in comparison to cars. And I bet they're not the best quality metal in the world being a 'novelty' part.
