Chassis/Body Roll Inertia values
Chassis/Body Roll Inertia values
(OP)
Hi,
Im after a more accurate roll inertia value for medium sized sedan style cars (around the 1200 - 1600kg mark). I have a value for formula style cars at 140 kg.m^2 (3300lb.ft^2) although im guessing this is much too low to apply to road cars. Anyone have any more accurate ball park figuers?
