Fitted 40mm lowering springs onto my 02 172 yesterday (and to clear up an argument that's been going on for ages no,you don't need spring compressors for a 172 the standard springs have hardly any tension) it looks a lot better it's lower but not that low that I look like I'm "on my way up maccys to put trays under my back wheels" the only thing that bothers me is the wheels sit too far in so my question is what sort of spacers and what size do I need to bring the rims level with the arches?
