Are you interested or are you asking how to do it? Yes, you have to trim off the lower spring perch and leave a small rib so that the threaded collar sites nicely against it, as you can see in the picture. The strut instert bolts in from the bottom so it's very easy to change them out with just the Koni inserts. You can also use any readily available 2.5" spring rates and easily adjust the ride height of the car just like the factory M030 option.
