That doesn't necessarily mean they need cooling. I'm not aware of any of the other racers having rear brake issues. You might consider an aluminum hat/improved rotor disc setup instead like Racing Brake etc.

Will cut 5 lbs of rotating mass too

The rotor material is way superior to OE, and way more durable with aggressive track pads ...

I just updated my brake ducts on the dedicated track car. (SCCA T4 class) I had ducts running from the old fog lights but with the new oil coolers I needed more space. I did something similar to this thread. I have the mx5 ducts on the rotor/hub to carry the air into the hub itself. a 2.5" hose fits nicely so I found some parts at home depot to add some 2.5" ducts to the plastic that scoops air to the radiator.

I found shop vacuum hoses are 2.5" and the little round end worked well. ($9 each)

Pulled the bristles off and cut it back to make a snorkel.

I drilled a 2.5" hole in the side of the plastic to insert the shop vac end in.

Used a couple rivets and epoxy to hole it in place.

Then to seal off that area I cut a piece of thin aluminum ($7 for 12"x12" enough for both sides) and riveted it to the plastic so separate the brake duct area from the radiator area.

OD4 where in VA are you?

Need to do this myself as well. I was thinking about skipping the aluminum bracket you put there to split the airflow - wonder if that will impact the cooling in the heat of the summer on the track?

which hose did you use?

I'm in the Warrenton area. I didn't have an issue with the engine temps after doing them but I do have a huge radiator and no AC radiator.

Not sure on the brand of hose it was left over for something else. It was 2.5" if I remember. OG racing sells some good stuff.
