As per the little, had these done today. At the same time i changed the topmounts, bearing, droplinks and lower wishbone bushes.
First thing to report is the drop... H & R Claim 35mm. i already had the sport suspension so the drop should be more like 15 - 20mm, but my suspension was 89k old so had probably sagged a bit too. Anyway, the drop was.... 0mm! I guess it'll settle and drop a few mm but for anyone who wants uprated suspension without lowering the car, this looks like the combo!
