Here is a picture of the Gen 1 brake duct on the rear. Does a good job and exactly what it was intended to do.
Now with the Gen 2s this ducted air not only cools the brake, but helps cool the outer CV axle and I would think a little on the wheel bearing. Regardless simple upgrade and is also IMSA approved for upgrading to Gen1s. Part Numbers are 991.575.334.8A and 991.575.333.8A . Like $130 each IIRC (so essentially free in Cupcar terms). Thought some of you might be interested.
so these are stock on the 2017/2018s, but option add-on to the 991.1s??
what do these run? have a part#?
