Care and feeding of your 6UL wheels

• Inspect your wheels before you mount tires for the first time. A scratched wheel with a tire on it is not warranteeable.
• Torque lugs to 70~80 ft-lbs ( 94Nm~108Nm)
• After first drive on brand new 6UL's, retorque once. Retorque lugs after every track session or autocross day
• Wash with mild soap and water. Strong degreasers will stain the finish
• Check track wheels for roundness and cracks every time you replace the tires. Track wheels get bent, it's a fact of life :) New radial runout spec is .025" lateral runout spec .015. Replace at .090 radial, .060 lateral
• 7~ 8" 6UL's can be single plane balanced for track use. The 9" might require dual plane balance (weights on front & back) due to the width.
