True, but those are more flat disc's to smooth the air going around the rear of the car vs these which are vented, finned, and attempting to serve as an active part of a cooling solution and actually protrude out into the airflowPorsche does on the MR kits they have for the gt3rs. That car is a nurburgring weapon.
I thought those were only to cool brakes? Going way back in the day to when Audi ran a couple of 4wd weapons in TransAm, they had those disc's on the wheels. I spoke to Walter Rorhl (think that was his name) who drove one and he said brake cooling was their use. Those cars were 4wd turbo 5 cyl if I recall correctly and they were supposed to be making around 1000 hp and they needed all the brake help they could get, tires being what they were back then.View attachment 88343
Supposedly they create extra downforce and improve brake cooling. Does anyone know if that's actually the case? Particularly for the Rotiform aerodiscs as they are probably the most popular. If it's true then surely I'd see these more often at the track?
They're as much of a style statement now as an effect. If there was a strong benefit to running them we'd see them being used at World Time Attack I feel and I can't recall seeing a single set.
Or to have more parts you can sell to people who think they're cool.Just understand that sometimes it's more about style than performance.
Ha! That's exactly what I was thinking.attempt to suck smoke out from under the fenders
Surely someone in here is a CFD expert, get on it!First, which way does the air go?
