Probably not going to happen to be honest lowering springs for the micra are shocking lowest I've seen are 35mm coilovers are a much better idea and cheaper in the long run
It's a Bodge, that's no doubt. You change the characteristics of the spring by chopping a bit off.
That being said, I will be cutting mine on the pickup when it's done. Figure I could buy a couple of sets and feck about until I got it where I wanted it.
I just lowered her on 30mm lowering springs, the back is fine (with a little rubbing) the front is higher than the back, got to go down.
The chap who will cut them says its all about the angle you cut them at, and has done loads of them.
