My front tyres are 245/60-15 Avons and the steering geometry is perfect, car goes straight even with hands off the wheel. Toe in is about 0 if not 0.2º in.
When driving over bumps the steering wheel tends to snap left or right and I need to keep a steady hand on it while driving on bad roads.
I was thinking in installing a damper for the suspension, before going through the steering box,like the offroad vehicles use.
You know, one damper on each side going from each tie bar to the frame somewhere in the center.
Has anyone experience with such a setup?
Will it work without making the steering too heavy?
