RGT-200
The RGT-200 is a compact transverse unit, designed for mid-engined sportscars (GT). The unit is produced with six forward gears, reverse, and is fitted with a Torsen type differential.

RGT-200

The RGT is a high tech racing transverse unit which achieves the maximum effective use of power, in conjunction with extremely stiff integral mounting points.

Gear changing is effected through non synchronising face dogs. An extensive range of gear ratios provides an excellent range of gearing requirements.
