Chassis Stiffening

[astroracer]

Adding bars out in front of the cross member will do nothing. Trying to stop twist, without a good cage, is not going to happen. All you are doing is adding weight. Lateral stiffness can be improved with a good K-member design but, to improve torsional stiffness, you need to have a good cage that is triangulated down to the chassis and ties the front and rear suspensions together.
