It s not the springs. Springs are from Eibach made to fit you can also use these springs on you're original dampers. You can order directly from eibach if you wish.

But it s not the springs which made the difference. It s the damper.

If the springs are to hard you loose to much comfort. This setup has better comfort then original dampers and can be adjusted to suit the track.

You can use original bmw top mounts so you don't have rattle problems.

Racing dampers with adjustable rebound and bump settings are nice if you use you're car only for tracks. This JRZ setup can be adjusted with 22 settings. From soft to hard. I tested it on road and track. Gives perfect comfort to drive to track. Then adjusted to hard and drive you're socks off on track. Perfect.

The JRZ wil be offered as a complete package for very good price.
