What is the drop height for these springs?

These AST lowering springs provide a 40mm drop for both the front and rear of your vehicle. This lowers the center of gravity and gives your car a more aggressive stance.

Are these springs comfortable enough for daily driving?

Yes, these springs are designed with a progressive rate to balance lowering your vehicle with maintaining a comfortable ride similar to OEM springs. They are cold-coiled on precision Wafios machines.

What does the lifetime warranty cover?

AST offers a lifetime warranty against breaking for these lowering springs. This ensures you have peace of mind with your purchase.
