Can the GT3 brake cooling ducts be mounted without modification to the .2 suspension arms or do you have to go to gt3 arms or aftermarket?

Not sure, the T comes with cooling ducts and they look good and function well. I would try those.

They already have cooling ducts/ deflectors if the car was equipped with RAS

Same part as the GT3? I'd be surprised.

So Porsche updated the Track Precision App in last couple of days so now easy to export video

I show today Ferrari Pista achieve 7:00.3 in a fast lap with Sport Auto Test Driver Christian Gebhart. The car used Michelin CUP2R K1 tires.
Same driver 2 years ago achieved 7:24 with a 991.2 GTS using PS4S tires.
Taking i to consideration that CUP2R tires are almost 20sec faster in the ring than PS4S i feel that in case someone takes a GTS with CUP2R K1 tires (i know Porsche does not approve this and keeps R tires only for the RS models) the car time will be quite close to 7mins.
Based on GT forum posts CUP2R tires Last for 1/3 of PS4S tires but obviously have significant time improvement.
Seems CUP2 or Troffeo R are the best options for a GTS truck use only and PS4S Best for daily use.

I am in the process of fitting a GT3 front bar. To my surprise those two openings at the front are NOT brake ducts. They just channel more air to the side radiators, just like the GTS does.
The GTS has Naca ducts underneath, and I will check, but it doesn't appear any different from GT3.

GT3 looked very different at the front (at least thats my recollection - havent been under a GTS for 6 months and no longer have one). The rears were definitelt in the form of deflectors IIRC.

Yes I know - I was refereing to what is underneath the car near and on the control arms e.g. deflectors, mouldings to direct air on the brake rotors - not pipe work from the front facia. The gaps circled are ducts for the radiators. .

Okay...the time has come that i am returning this car to 100% stock. Do i have any 991.2 owners in the Central Florida area that are interested in suspension upgrades? The rest of the gear is not getting fire saled, as it was used twice on track. Please call the shop and ask for Wray.
