Calculation Methodology

Dynamic Weight Transfer (kg) = (Mass kg * Deceleration G * CoG Height m) / Wheelbase m. Dynamic Front Load = Static Front + Weight Transfer. Ideal Front Bias % = (Dynamic Front Load / Total Mass) * 100. Rear Bias % = 100 - Front Bias %.

Frequently Asked Questions

Most production street cars operate with a 65% to 75% front bias to guarantee that front tires lock up slightly before rears for inherent directional stability.
