Can anyone tell me why cf48's are shaped the way that they are? Do they help to cool your brakes or are they just styling? And are they good for track racing?

 

Got a pic?

 

heres a tread on them but it has no technical specs https://honda-tech.com/zerothread?id=1466727

As to how good they are for racing, I really don't know.

Brake cooling, the area and heat sink like fins would help cool the rim off better. It does make contact with the brake rotor so the thermal energy would be transfered via conduction. Down side is you can expect a lot of thermal contact resistance between the rotor and rim. Also they would hinder air flow going in and around the rotor. So it's really anyone's guess as to whether or not brakes cool better.

Most people don't by rims based on the ability for it to cool brakes. Just buy some of those ducts if you are concerned or get bigger brakes if you are going to do some serious track racing. Brakes don't overheat under normal circumstances. Most people buy rims for looks, it's a personallity thing. So I would hazard to guess that the rims were infact designed for their unique style.

Hope this helps a little. I have no real facts to base this on. Just general knowledge and reasoning.

Cheers.
