Left rear : 21 15/16".
The car is listing slightly to the right.

Assuming that the front/rear balance is good, but the car is offset to the left due to sagging on the right, but in equal amounts, let's call it 21 11/16" from lower rim lip, through center cap, up to fender.
That's only 550.9mm, on 18" wheels.
So, provided I measured everything correctly and my assumptions are sound, those Spec-R's are a full inch lower than the BMW Performance suspension in the rear, and over 1.5" lower up front. Curious to see where the Eibach's get me when everything is back in ship-shape.

I'm at 575mm / 564mm front / rear. Adjusting for the fact wheels are 17" that would give 18" equivalent of 587mm / 576mm which is pretty much within 5mm of the sheets posted above (remember the front 18" BMWPS is an obvious error and should be 582mm). So you are quite dropped at 551mm.

Were the Swifts designed for an E88 or are they general E82 springs? If they were E82 one size fits all that would explain the large drop.
