- An alignment. Any change in ride height changes camber and toe. Set your final height first, then align.
- Camber and toe adjustment. Bigger drops often need adjustable arms or camber plates to align properly. See alignment and camber kits.
- Healthy dampers. Springs work best on dampers in good condition. If yours are old, consider replacing them or going to coilovers.
- Wheel and tire clearance. Check clearance at full lock and full compression, especially with wider wheels. Our ride height and wheel fitment calculator shows how much drop and offset change you are planning.
- The right spring rate. Compare the rates listed here with what our spring rate calculator suggests for your car's weight and use.
