  • ARS(tm) suspension consists of ARS(tm) arms, graphite 0degrees Chubs for optimal flex characteristics, hard suspension block, ARS(tm) suspension block, and ARS(tm) linkage connecting the holder to the suspension block
  • ARS(tm) linkage angle ndash; adjusted by adding/removing shims on the steering block and ARS(tm)holder ndash; changes the toein characteristics of the rear tires during chassis roll.
  • Aluminum suspension holders featuring Integrated Suspension Settings (ISS) for quick and easy suspension geometry adjustment
  • Suspension holders allow more durable mounting of the suspension arms, so the suspension geometry of the car does not change even after hard crashes
  • Suspension mounting system allows for very free arm movement, which gives higher traction, smoother driving, and improved steering
  • Suspension holder system allows suspension arms to be mounted independently from bulkheads allowing for elongated chassis flex to generate more traction
  • Independent suspension holders allow for more precise and fine setup adjustments via different bushings
  • Rear suspension aluminum holders feature integrated toein
  • Chubs available optionally in standard caster angles (2degrees, 4degrees, 6degrees); available in three hardnesses (M ndash; medium, H ndash; hard, G graphite)
  • Hard front steering blocks increase steering response, decrease front tire overheating in hightraction conditions
  • Small, robust steering blocks made from special proprietary composite material, available optionally in 3 hardnesses (M ndash; medium, H ndash; hard, G graphite), and feature 2 Ackermann positions
  • Rear uprights give increased stability; available optionally in 3 hardnesses (M ndash; medium, H ndash; hard, G graphite)
  • Rear uprights feature integrated 0degrees toein to prevent suspension geometry changes in serious crashes
  • Arms feature innovative SFATM (Suspension Flex Adjustment), innovative and unique graphite stiffeners allow for superquick suspension flex adjustment to easily adjust the traction of the car under various track conditions
  • Suspension arms feature integrated antiroll bar mounts; rear arms feature 3 different antiroll bar mounts for superfine adjustment of the rear antiroll bar
  • Suspension arms made from graphite material for improved traction and stability of the car
  • Antiroll bar system is mounted to the bulkheads via bearings for extrasmooth movement and maximum precision, and side play is eliminated by aluminum bushings.
  • Antiroll bar height is adjustable via simple screw adjustmenthellip; quick and easy
  • Front 1.4 mm and rear 1.3mm antiroll bar wires included
  • Easilyadjustable wheel offset using optional wheel hubs(0.75mm, plus0.75mm, plus1.5mm)


  • Lightweight middle layshaft CNCmachined from aircraft aluminum
  • 84T 48P spur gearndash; extrahard material, wobblefree design
  • 38/20T (1.9) internal gearing for efficient, highperformance drivetrain
  • Premiumquality, Kevlar(tm)reinforced drive belts
  • Chubs with large openings for quick and easy assembly/disassembly of the CVDs and ECS drive shafts; prevents collision of CVD or ECS drive shafts with C8209;hub in serious crashes
  • Superlight drive axles
  • Front ExtraStrong ECS drive shafts equalize the speed between the drive shaft and the wheel. With a unique 2piece joint between the axle and the wheel, any extreme wheel turning angle is divided into two shallower angles without joint binding. This means that regardless of the cornering speed and wheel angle, the inner wheel will not bind or vibrate. Drive through corners is more stable, more precise, and easier to drive.
