Cooling ducts for front rotors

[juse]

Is there any advantage to route cooling ducts to std solid rotors?
I suppose it works well with ventilated discs but is it worth it on solids??

IMO yes. Why not? if you can provide your brakes with air flow it would help with overheating and fading issues. Since the back side of the disk is covered and cooling rely on heat dissipation from the outside face of the disk...

An issue that may appear?
If the cooling vent is placed immediately after the caliper, could this be a problem and wrap the disk? and what if the vent is placed just before the caliper? would there be enough time to cool the disk?
What is the "correct" ie best place for the vents?

Also what kind of angle on the tube is better? I suppose that you would cut a hole and then weld a tube on the disck back plate to hold the flexible air hose as I remember someone doing it here a looong time ago.
Correct me if im wrong

This is the thing was thinking. And to use the stock horn grilles for the other end.

Craazy Cooter has done it just the way I think I will.
But which do you think would be the best place for the duct connection in backplate?
I`ve seen pictures of cooling ducts to rotor and others that direct the air to caliper.
Any thoughts?

It sounds cool and all, but do you really overheat your brakes?

[beetle1303]

Since all the heat produced while braking is located at the caliper, Iwould go for the caliper and probably some area after it, because you want to aid the disk cooling as well... Caliper is thick enough for the air to cool it sufficiently IMO except if you are running the M030 ( the finned brembos which are offered as an upgrade kit with rotors through Porsche). I got them from a 996 Turbo that the guy swap for PCCB. He sais that their performance was above the stock 996 turbo items.

Otherwise you could do both... Just be extra careful with the hoses and fouling issues...

I`m just taking the most out of stock brakes before a future upgrade to Porsche package.

Much of the heat from a solid rotor is dissipated through the wheel, which is likely to be the origin of alloy wheels with directional spokes.. Note Porsche offered winter wheels, again likely to do with brake cooling.
