Note: Comfort: 1.0-1.5 Hz. Sport: 1.5-2.0 Hz. Race: 2.5-5.0+ Hz. Front should be 10-15% lower frequency than rear for good pitch control.

Reference

Wheel Rate = Spring Rate x Motion Ratio² Ride Rate = (Wheel Rate x Tire Rate) / (Wheel + Tire) Ride Freq = sqrt(Ride Rate / mass) / (2 x pi) CPM = Hz x 60 Mass in slugs/in = Weight / (32.174 x 12)
