The front is a true coil over, the rear is not (unlike the GT4).
The GT4 is a race car, with different performance requirements, maintenance schedules, and homolongation rules.
The AP brakes are racing parts and need to be rebuilt probably annually due to the lack of dust boots. The same goes for the Ohlins dampers.
The Brembo GT brakes are built to road-legal requirements and can withstand all types of weather conditions, be it snow, ice, or rain. They need to be salt tested to simulate driving in winter. They require minimum maintenance as you would expect on your single pot sliders. And probably never need to be rebuilt within the life of the car.
As described in the press release, the GTS is meant as a track car and/or club racer, far from a professional level race car.
