Eibach Pro-Kit beim G21

There´s a service job in the BMW tester where you enter the new height and this new data will be written into the VDP ECU.

My car had no adjustment and drives just fine.

Ok, thanks.

Still not sure to go with Eibach. In real life Eibach is lowering 30mm m340i?

15-20mm would be ideal.

There are many pics from M340i with Eibach springs in this thread.

For example #583

I also wanted the car lowered by about 20mm. Therefore, the Eibach springs are perfect.

If you want more (about 30-40mm), you should take the Eibach Sportline or the H&R springs.
