The Zamp Z-Tech 2A, 6A and 8A are all designed for a more upright seating position. The SFI Foundation's seatbelt guide for upright seats covers seat backs reclined up to 25 degrees. Seats reclined further than that call for different setup guidance.
For strongly reclined seats, such as most formula cars, FAST RACER's guidance is to choose a 30-degree head and neck restraint instead of a 20-degree, upright-seat device. Compare angles across brands in our HANS devices range.
