I have not, just what I've heard from friends and coworkers and what the instrumented test have said from rags and the overall silence from the media on the braking.
And yeah, not doing any of that to go have fun around PIR. The car is already a compromise and a third car. Pointless spending money on a compromise just to do the thing it's supposed to do and told it can do out of the box. I'll hit up Pat's Acres and go carting before dropping a few grand at Dan's on a BBK for the GR86 or BRZ. Sorry Dan.
The R brakes on the GTI became the standard brakes. So for I think 4 model years all cars came with them. My '19 SE with the PP option only had DCC, bigger rear bar, and telemetry. The standard MK8 brakes are supposedly even better. The entire GTI is better and a more capable track car than this BRZ is out of the box. Alignment and tires and done. Which bums me out about the BRZ.
