So this is the air deflecting and brake cooling setup on the base Cayman. See the difference in shape of the air deflector/front wheel spat thing compared to the GT4? Also, you can see the brake cooling air guide here on the base Cayman.
The rear brakes on the Cayman get cooling air directed from this air guide mounted to the lower suspension arm.
Everyone loves the GT3RS. A news crew from the local Vietnamese Saigon TV station located down in the OC was on hand checking out the show.
The front fender vents on the GT3RS are massive. There is a plastic mesh in them I imagine to prevent debris from flying out of the vents.
Super wide Michelin Pilot Sport Cup 2 tires are on the rear. Those rear PCCB brakes are the sizes of dinner plates, but they look small inside the 21” wheel. Of course, the ‘RS’ is perfectly horizontal, because auto show.
