Toyota says the Griffon, which is not intended for production, has been developed specifically for track driving with extensive modifications to reduce weight and strengthen the chassis.
TRD has replaced the standard GT86’s Torsen limited-slip diff with its own mechanical diff and the final drive ratio has been reduced to 4.8:1. Coilover suspension units, a new oil cooler and TRD monoblock callipers with race-spec brake pads are among the other modifications.
The GT86 Griffon features a carbonfibre roof, bonnet, doors, bootlid and rear wings, while carbonfibre-reinforced plastic has been used to construct the bumpers, front wings and rear diffuser. The standard car’s glass windows have been replaced by polycarbonate units.
A new driver’s bucket seat, gear knob, ignition button and gauges – all from TRD –are installed alongside a Momo steering wheel and Takata seatbelts.
