AST 4200 Monotube Coilovers BMW E36 3 Series incl. M3 92-99

AST coilovers are monotube, high pressure nitrogen shock absorbers. Why do you care? Most other products on the market are twin tube designs and are not pressurized. Monotubes offer the biggest pistons for more control. Gas pressurization means the oil will never cavitate around the piston. This is particularly important in environments where the vehicle makes rapid changes in direction such as autocross and road racing.
