Steel Chassis · 1.2 mm

Maximum traction when the track offers little grip.

Eighteen months of development went into the SP2. The DNA of the SP1 has been retained, but everything around the concept has been completely re-engineered. This is the steel specification: a 1.2 mm plate, the heaviest and most planted of the three chassis variants.

When the track is still green, dusty or cold, this is the chassis that finds grip where the other two cannot.

Material: 1.2 mm steel

Character: Heaviest and most planted

Best for: Low grip, dusty conditions

Scale: 1/10 EP Touring

All three chassis variants use the same 110° steel screws, making it easy to switch between the different chassis while keeping your spare parts inventory simple.

Technical Highlights

Suspension

• XS shocks and springs for reduced unsprung weight and faster handling response
• Coaxial shock and pushrod geometry for smoother operation, less play and a lower moment of inertia
• Shock body mounted directly to the bulkhead for reduced friction and unsprung weight
• 3 mm longer suspension arms with mounting points positioned 6 mm closer together for improved corner speed
• Adjustable rocker height via a slider for quick and precise tuning
• Steel pushrod components instead of ball cups for reduced wear, weight and friction
• Delrin plastics and polished steel ball studs throughout

Sway Bars

• Ultra-lightweight, ball-raced and adjustable from above
• Lowest possible centre of gravity with a minimal number of components
• Compatible with 1.0–1.3 mm sway bars, with front and rear components fully interchangeable

Hubs, Steering & ARS

• Lowered axle height for a wider ride-height tuning window
• Oversized 6×11×4 mm inner bearing for increased durability and reduced play
• Optimised scrub radius for a more aggressive steering response
• 8.0 mm steering rack with optional steering lock stoppers and a lengthened rear toe link
• Low-CG one-piece servo mount with enlarged locating pins
• Direct mounting for analogue and digital caster tools, with integrated aero disc option

Bulkheads, Motor Mount & Top Deck

• 4 mm raised top deck mounting for more rigid and progressive chassis flex
• Raised diff and spool position for increased corner speed and improved driveability
• FL/RR and FR/RL bulkheads are interchangeable, reducing the number of spare parts you need to carry
• Motor raised by 0.5 mm for more material under the motor pocket
• Screw-in steel layshaft with laser-etched belt tension positions
• Adjustable front and rear belt tensioners included; optional centre tensioner available for Modified
• Cuttable top deck tabs for precise flex adjustment

Drivetrain

• Threaded aluminium diff halves with optimised gear spacing
• Larger driveshaft bearings without couplers for reduced friction and wear
• Lightweight, hardened outdrives and driveshaft components
• Larger centre pulley bearings for increased rigidity under high loads

Bumper, Body Mounts & Hardware

• Low-CG front bumper assembly with integrated stoppers in the front bulkhead
• Carbon bumper mount with a pocket for the INOV8 Adjustable Hood Support
• Split-style rear body mount for a lower moment of inertia and adjustable bulkhead flex
• Nickel-plated YFS screws on top of the car
• Steel 110° countersunk chassis screws with 2 mm hex
