Just adding a note on my experience with the springs. When I bought my car, 2012 1.4 Multiair, in 2016 it had had the offside rear one replaced. The nearside rear duly broke in 2017 and since I needed to get it back on the road quickly I purchased replacement from Chrysler but at the same time ordered a full set of the Eibach springs since I knew sooner or later based on the comments on this Forum that I'd have a problem with the fronts. They were being quoted as out of stock at Eibach at the time hence the decision to get one from the local Chrysler dealer. The Eibach springs took several weeks to arrive but they did eventually (£124 for the four) and since then have been sitting in the garage but sure enough a couple of weeks ago the front nearside spring broke so this gave me the opportunity to replace all four with the Eibachs. I've attached some photos to show before and after and I think it's clear there's a definite lowering. Unfortunately I wasn't organised enough to actually measure anything! They are noticeably stiffer and I'll keep an eye on them to see if they lower any more as they settle in.
