PCA Dissects the New 992 GT3 Cup

Redd · 03-13-2021, 08:42 PM

Interesting things I noted:
1. Rear brake ducting blows air onto the disc surface, not into the inner annulus.

2. Ducktail below the swan-neck rear wing. Case for having both a rear boot lip spoiler and rear wing (on M3) at the same time?

Wow! I know it's a factory built race car, but the fact these improvements carry into the GT cars is incredible. Thanks for sharing!

These are very different cars than our touring cars but I wish the M division would put more of an emphasis on the Motorsport.

It looks like the rear ducting is being deposited on the inner rotor surface, but it should still be angled to flow toward the inner annulus

A arm front suspension for me. Hopefully Cayman finally gets the same treatment.
The fact it's hampered by strut rear is a shame among other things.

i think porsche is moving more towards using underbody aero to cool brakes rather than ducting for a few reasons- throw air in the direction of the brakes, and redirect air under the car to the outside of the car. the second part creates downforce.

I've been told that there is no substitute.

Its is powerful - when you put it on the whole range of your line with a sticker that says "///M" - and upcharge a supposed "Performance Package". Including SUVs.
