As I’ve recently changed to non run flats, I need to invest in a space saver wheel and a compressor. Don’t want to carry the space saver around, so looking for a compressor to stay in the boot. Have seen the BMW kit but it’s about £85, and from what I can see it’s not even digital it’s analogue. So is it really worth it? What has everyone else gone and bought. And where have you got hold of your space saver. I’ve got 18’s on so not going to be much of a space saver due to the brake set up.
