I found this great deal and just want to pass it along... I was on the fence about getting the GT3 brake ducts - the jury is out on just how much more effective they are over OE. The GT3 ducts are bigger and more sweeping. So logically, they should direct more air to the brakes, right?
I found them for less than $15 for the pair + shipping and decided to take the plunge...

They showed up a week later and will put them on the car this weekend.


For anyone interested, you can get them from Pelican parts.
Here are the part #'s I have for L & R:.

Disclaimer: Just because many owners got these to install on Boxsters and Caymans, I make no guarantee these parts will fit your car. So, don't cry to me if you got them and they don't fit.

 

I got mine from Suncoast. It's a must if your Pcar sees the track.

 

I think they really work. I kept getting intermittent brake pad warnings (despite my pads being fine) at track days. Mechanic felt it was likely heating up of the sensor.

I put on the GT3 ducts and my last track day went great with no warnings. they are much bigger than boxster/cayman OE ducts adn have to direct more cooling air toward the brakes.
