With this car seeing more and more track duty a few updates were in order including the TechArt lowering spring kit and a full front/rear Brembo GT slotted brake system.

In she comes with a complete mexico blue wrap for protection at the track...


With multiple track days (and pad/rotor changes) the weight/speed and thermal capacity of the stock braking system (carried over from the Cayenne) yielded these results. The pads were worn out, rotor worn through...


Stock caliper and worn-out rotor in front:


Same story in the rear (notice the uneven surface etc...):



Pads worn down severely after a couple of track days:


Off come the rotors, stock lines and calipers and on goes the TechArt lowering spring kit:


The GT system awaits going from 13.3inch fronts and 13.3 inch rears to 15-inches:


In front now sporting a front 6-piston GT caliper and 380mm two piece slotted rotor for improved cooling properties. Stainless steel Goodrich lines and race pads are also added. The overall bite is much improved as are the thermals.


And the fully upgraded rear Brembo GT kit, with a four piston monoblock caliper, 380mm slotted rotors, Goodrich stainless lines and racier track pads:


Front fitment is not an issue with 20-inch HRE P40SC monoblok wheels...



Rears are a-ok check:


It's hard to make more power on these 991s but our age-old trick since the 996 days seems to always work- 5hp right there:


After a test-drive and strict bedding-in procedure she's ready for more track days:




Close-up:

 

Don't like the rear spoiler.

 

The hre's are absolutely gorgeous.

 

Those TechArt springs give the perfect drop.

 

great looking car!

 

Rather than upgrading the brakes, I would get a second set of track tires and wheels. 20s are too heavy and probly causing the overheat.

I have never had any overheat with Porsche stock brakes.
