they look very stupid imo....but like subject..

 

better cooling supposedly

 

Chavs wet dream.

Soon they'll be down B&Q sticking circular saw blades to their drum brakes to imitate them.

 

Don't know mate, but never seen a car with them fitted

 

emphasis on the supposedly there.................if it worked the rally / touring car boys would have started using them years ago..........

 

true but thats the speel they give out!

 

tryin to take the idea from bikes.

Like the ZX10R & 6 have wavey disc's to aid coolin & deglazin plus pad wear or something.

Not sure if id like em on a car tho

Jb

 

marketed as something to do with weight as well iirc

 

you mean the bollocks they give out surely...........I've got the wavy discs on my mountain bike and when I replaced them I asked what advantages there were - and was told none at all. Just looks different.....

 

on a bike where you have a thin disk of a big diameter i can see it possibly helping, on a car, i wouldnt want to trust them at all, its just less of the much needed pad area IMHO

 

the surface area is larger than that of a disc of the same diameter if round so heat WILL dissipate faster off it,its simple physics.

 

Aaaaaaaaaaaaahhhhhhhhhhh, when I bought my Cossie it had a set on the front, theyre called "rotary discs" and they were fookin shit!, they were warped as well really badly, they were £120 going of receipt I inherited with the car,

 

How can it have more surface area of a round disc the same diameter? It's got bits cut out?
