Schumacher CAT PB-M

The Schumacher CAT PB-M (K222) is a 1/10 scale 4WD competition off-road buggy kit from the iconic CAT PB platform, created to honour the late Phil Booth. Blending modern engineering with Schumacher’s racing heritage, it focuses on efficient shaft-driven power delivery, a low centre of gravity, and easy maintenance for consistent lap-after-lap pace.

A refined driveline, optimised suspension geometry and a narrow 7075-T6 aluminium chassis provide sharp handling and stability on dirt, astro or carpet. Finished with an aggressive JConcepts S2 body and matched wing, the CAT PB-M is engineered for serious racers seeking performance and durability.

Key Features

• All-new shaft-driven 4WD platform for efficiency and reliability.
• DIRT Spec: Shaft drive with three differentials for low-grip tracks; includes CVD rear driveshafts and U/J front.
• MOD Spec: Shaft drive with two differentials plus FAB (Front Adjustable Brake) unit/slipper for high-grip surfaces; includes U/J driveshafts front and rear.
• Oil-filled, small-diameter differentials with gasket seals for superior sealing, low weight and low CG.
• 80T spur gear, simple to fit.
• Diff-height eccentrics with five settings to tune for any grip level.
• Fast-access transmission housings for quick diff changes.
• Front and rear U/J driveshafts for durability and improved bump handling.
• Stronger front hub carrier bearing assembly.
• Alloy motor and layshaft mount housings with laser-etched eccentric adjustment for precise gear mesh.
• Long front wishbones with moulded anti-roll bar ball and large-span inner hinge pin bosses for impact strength.
• Revised rear wishbone for improved flex characteristics.
• Suspension pills/inserts to adjust track width, roll centre, toe and anti-squat.
• Robust front and rear suspension straps/blocks; strong rear hinge pins.
• Rear hub carrier with seven height options; camber plate with multiple positions.
• Improved anti-roll bar fitment with matched front and rear bars.
• S2 4 mm shock towers with angle adjustment and multiple camber link positions.
• Lightweight front bumper reduces overhang and improves clearance on tight kick-ups.
• 7075-T6 2 mm hard-anodised aluminium chassis; light, narrow layout keeps weight inboard.
• Composite side pods for dirt sealing and added stiffness.
