Curious to hear how they go. Annoyingly the 5.0 gen didn't get much love for spring options and from what I know most may not be very suitable - with H&R being the closest but with a pretty aggressive drop.

I got the sport ones with a 1.3” drop. That was the least I could find and I measured as best as I could so hopefully it’ll be correct. I also have 20mm spacers on the rear which should be about right. Fingers crossed.

Excellent! I was wondering because the part numbers on those springs seem to mainly be for an XF (29117-1) vs 29299-1. I found a matching set on my version of eBay for cheap so was interested in trying them out if they seem to work correctly.

H&R is no help as one of their sites lists 29299 as being correct (https://hrsprings.com/application/se.../16/Suspension) and (https://www.h-r.com/artikel/?article...uppliernr=4311) suggests 29117 as being correct! I would imagine if there is a difference, the 29117 springs would be slightly stiffer as the XF is a bit heavier than the XK.
