Peugeot - Citroën MCM 6-Speed Gearbox Gear-Type LSD

Description and Applications:

The RSX lightweight (5.30 kg) Torsen-type LSD is designed for PSA MCM gearboxes, also known as MC6, MC 6-speed, and BVM (Boîte de Vitesses Manuelle) MC6 in France. These gearboxes are paired with PSA 1.6L THP turbo engines and are found in Peugeot, Citroën, and the 2nd-generation BMW Mini models:

• Citroën DS3 & DS3 Racing
• Peugeot 207 1.6 THP GT & 207 RC
• Peugeot 208 GT, 208 GTi
• Peugeot 308 GTi
• Peugeot RCZ 200 & RCZ-R
• BMW Mini Cooper S / JCW 1.6 THP/Prince Turbo (2nd Generation) R55, R56, R57 & R60

Key Features:

✔ Superior Strength & Durability
Our Torsen (helical gear) LSDs are manufactured from FORGED Nickel-Chromoly steel, featuring specialized heat treatments and surface enhancements such as super sub-zero treatment, shot peening, and WPC. These processes significantly increase surface hardness, ensuring maximum strength and longevity—making this LSD the ideal choice for high-torque, high-power turbocharged engines, including drag racing cars exceeding 1,000hp!

✔ Enhanced Traction & Cornering Performance

• Provides a smooth and constant distribution of power to the wheels.
• Prevents torque steer or pulling effects on the steering wheel, unlike some other LSDs.
• Optimized helical gear design increases traction and cornering speed, outperforming some plate-type LSDs on the market.

✔ Maintenance-Free & Noise-Free Operation

• Unlike plate-type LSDs, this gear-type LSD requires no maintenance and operates without noise, making it the perfect choice for both road and track-day cars.
• Also highly effective and cost-efficient for race, drag, and rally cars.

Recommended Uses

✔ Street Driving
Our Torsen (gear-type) LSDs provide enhanced traction for everyday driving, improving vehicle stability and performance, particularly in adverse weather conditions. Their seamless operation ensures a smooth driving experience without the drawbacks of traditional plate-type LSDs.

✔ Track Days and Performance Driving
On the track, our LSDs deliver consistent power distribution to both wheels, optimizing cornering speed and acceleration.

✔ Motorsport Applications
Widely used in rallying, circuit racing, time attack, and drag racing, the RSX Torsen LSD provides efficient torque distribution to the wheel with the most grip. This helps reduce understeer in front-wheel-drive vehicles and oversteer in rear-wheel-drive setups, resulting in more predictable handling, improved cornering speed, and better traction.

🔹 Extras Included:

✔ Special Ring Gear / Crown Wheel Bolts (Free of Charge!)

• High-tensile 12.9-grade steel bolts for a secure and reliable installation.

Unmatched Reliability – 5-Year Motorsport Warranty

As a testament to our quality and reliability, we offer a 5-year motorsport warranty against material or manufacturing defects on our range of Torsen LSDs.

Important Notes:

⚠ Recommended Gear Oil:

• Use OE or fully synthetic gear oil without shockproof additives or friction modifiers.
• Avoid "LS" (Limited Slip) gear oils, which are designed specifically for plate-type LSDs.

⚠ Pre-Lubrication Before Installation:

• It is recommended to add some gear oil to the LSD before installing it into the gearbox.
• Our LSDs are assembled with anti-rust oil at the factory, but this oil does not provide lubrication.
