Suspension Designs – Different setups (MacPherson strut, double-wishbone, multilink) require unique shapes/mounts.
Vehicle Needs – Economy cars use simple stamped steel; performance/off-road models need forged aluminum or reinforced steel.
Adjustability – Some allow camber/caster tuning (e.g., aftermarket arms with bushings/heim joints).
Space Constraints – FWD/RWD/AWD layouts demand varying arm lengths/angles.
Durability vs. Weight – Balance strength (steel) and lightness (aluminum/composite).
Short answer: Variations optimize handling, cost, and fitment across vehicles.
