Different cars can be lowered by different amount, but a general rule is that most vehicles can be lowered 30-40mm without any issues.
Spring will wear over time and mileage, so if you replace one the car could sit lower one side, or have a softer spring one side, this could lead to instability or even braking.
Ideally yes, as the lowered spring will be firmer than the original, and the original damper may not have enough rebound force to control the firmer spring. A performance damper such as the Koni STR.T or Koni SPORT is ideal.
The warranty period is two years from the date of purchase, and any claim will need to be made through your original supplier by completing a claim form and retuning it with the spring, however warranties are very unusual and it is really unlikely you will need to.
