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.

How does the v4 differ from the GP Tech v3?
The v4 is the latest generation of the GP Tech platform, updating construction and detailing over the v3. Both carry the same dual FIA + SFI homologation, so the choice comes down to the newest features versus value.
