I bought the APR carbon fiber brake duct kit a few month back and it worked great with the stock caliper.

Note that the APR duct system works perfectly with the AP RACING / ESSEX Sprint kit. Not only it fits but it blows fresh air onto the rotor AND also to the center of the hub, which apparently is the more efficient and recommended way of cooling if you listen to the manufacturer of the ESSEX kit. The fit is very tight as you can see. It actually rubbed a little bit when I installed it but it went away after my first laps.

To check the temperature without the brake ducts, I added an Alcon heat sticker to my caliper and fully tapped the brake ducts, result: +- 330F.

Considering my brake pads (Carbotech XP12)start operating at 200F and all the way to 2000F, I don't think the ducts are needed.



Now that I upgraded to big brake kit. I don't think I need the ducts, but I am curious to hear your feedback.

Should I keep the ducts and try to keep my temperature as cool as possible to minimize wear ? or should I remove it to get i higher temperature and improve performance of the pads ?
