How much lower is a Sport compared to the SE mines an SE and looks alot higher than the sport, aslo how much are sport springs is it worth getting OEM to go that bit lower or would I be better with aftermarket

also are the sport springs stiffer I had a Sport behind me today(hello if it was you going up beacon lane) and when we went round the roundabout it still looked a bit rolly but maybe it was just because I was looking were I was going rather than watching how it handled and couldn't really pay much attention.
