The stock Mayhem setup is proving to be ultra-competitive on medium to high traction tracks. For low traction conditions we've developed two setups that have proven to work really well on slick tracks. If your track is typically hard-packed and slippery try one of these two setups:
Setup 1 Driver- John Adams Track Conditions- slick to medium traction Front Suspension Track Width- 305mm (stock) Camber Angle- 1.5 degrees Caster Position- forward Toe In- 1-degree toe out Roll Bar- 2.0mm Ride Height- drive shafts level Rear Suspension Camber angle- es(?) (stock) Roll Bar- 2.5mm Ride Height- arms level Hub Roll Center- lower hole Hub Position- hubs forward Gearing Clutch Bell-13-tooth Spur Gear- 46-tooth Clutch Shoes/Springs- Mugen carbon shoes MUGC070 and 1.0mm springs MUGC0708 Differential Fluid Front- 5,000 wt Center- 10,000 Rear- 3,000 Tires Type- Pro-Line Crime Fighters Compound- M2 Liner- Firm Front Shocks Pistons- 1.7mm x 2 (drilled) Oil- 45 wt Springs- Sportwerks red SWK3049 Mounting position top- upper outer Mounting position lower- outer Rear shocks Pistons- 1.7mm drilled Oil- 45 wt Springs- Sportwerks red SWK 3059 Mounting position top- middle lower Mounting position lower- middle
