Yokomo RS2.0 asphalt setup with 21.5T motor?

Assuming a 21.5T Yokomo RS2.0 on medium-grip asphalt, start with about 5 mm front and 5.5 mm rear ride height, -1.5° front toe, and +3.5° rear toe. The 21.5T motor does not require a different chassis baseline; grip level and tire choice will matter more.

A practical starting setup is:

• Camber: -2° front and rear, as a general 1/10 4WD touring-car asphalt baseline.
• Ride height: 5 mm front and 5.5 mm rear, matching RS2.0 medium-asphalt setup data.
• Toe: -1.5° front and +3.5° rear, values used on RS2.0 asphalt setups.
• Differentials: front spool and 3,000 cSt rear fluid; the RS2.0 asphalt data also lists 450 cSt shock oil and 3-hole pistons.
• Tires: Ride tires are listed for medium-grip asphalt on this car.

This should give a stable baseline with enough rear toe-in for drive and straight-line security. Check ride height on the track surface, then change one setting at a time. If the track is low-grip, tell me that and what tires you’re running, since the setup should shift for those conditions.
