RGT-200

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.

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.

KEY BENEFITS

  1. Adaptable design suitable for both front and mid-engine applications
  2. Designed for optimum weight distribution with the gear cluster located in front of the final drive
  3. Proven endurance racing components make this a reliable choice
  4. High performance Powerflow™ plate-type limited slip differential
