FAQ

Why is this suit homologated to both FIA and SFI?
Dual homologation means one suit covers two rulebooks. FIA 8856-2018 is required for international competition and most road-race series, while SFI 3.2A/5 is the standard recognized by US-based sanctioning bodies. You can run road courses, club events, and US series without owning two suits.

What does boot cut change?
Boot-cut legs are shaped to go over the top of racing boots rather than tucking inside them, which many circuit drivers prefer. Protection and dual homologation are identical to the standard GP Tech v4.
