What does the spring rate of 7.0kgf/mm mean for my car's handling?

A spring rate of 7.0kgf/mm (approximately 392 lbs/in) is stiffer than most factory springs. This means it will resist compression more, leading to less body roll in corners and a more responsive feel when steering. It can make the ride firmer, especially over bumps.

Will this spring fit any coilover kit?

This spring is designed for coilovers that use a 65mm inside diameter spring perch. It's important to measure your existing spring's inner diameter to ensure compatibility before purchasing.

Does this spring come with any hardware?

This product is for the coil spring only. Any necessary hardware, such as spring perches or locking collars, would typically be part of the complete coilover assembly or sold separately.
