Are there any brake cooling kits knocking around or does anyone know someone who makes them?
Looking at the type that replaces the fog lights and have silicone flexy to a duct that sits in the centre of the brake disc.

Thought about this. Does these fender louvres also help to vent the breaks?
If they could be an option to cool breaks even further?

No, you have to have forced air blown directly onto the discs/calipers to make any difference. If anything the louvres may reduce front lift but only if you run without arch liners

They'd have to suck better than a twenty dollar whore to do that 🤣

I have one of these kits, although like most stuff I buy not fitted it yet. Air forced through the front fog light (which has to be removed) and onto the disc

I found the fog light holes werent big enough to make a lot of difference. On my race car I had 15cm x 8cm ducts where the fog light holes were and just had the pipe directed onto the disc. Never had the brakes overheat in 6 seasons. It would, however, look sh*t on a road car.

I've fitted ducts to replace the fog lights, and found my brakes don't really fade at all now, plus subjectively the car feels far more stable at very high speeds now.

Mine is a straight pipe with a 45deg kink to point at the discs.

Cheers chaps.
Had another look at the kit and the ducting is stepped down meaning no real airflow so I’ll look at making some of my own back plates up I think. Anybody know what the OD of the foglight boss on clam is to size the biggest ducting I can

You don't really need the backplates. Directing the pipe end onto the disc and caliper is good enough, that's what I did, zip tied the pipe to the wishbones
