The suspension geometry on a classic car affects everything about how it drives, and most classic cars were set up from the factory for comfort and durability rather than handling performance.

Front camber: factory specs typically call for slight positive camber that provides stability under cornering but sacrifices grip. Moving toward zero or slight negative camber improves cornering at the expense of straight-line tire wear.

Caster: more positive caster improves straight-line stability and steering return-to-center at the cost of heavier steering effort. Manual steering cars benefit from more caster because the return-to-center helps compensate for the lack of power assist.

These adjustments don't require aftermarket components for most cars — they're within the adjustment range of the factory suspension. They do require a proper alignment machine and a technician who understands what the goal is.
