FSDs are designed to work with original springs or small lowering. Many people like them with Eibach Pro kit (that are 30mm lower and not 35mm, its H&R springs that are 35mm). But some people don't like them as the shorter stiffer springs may be too much for FSD to control. The sportlines are 40-50mm lowering and will be pretty stiff so I doubt FSD will be able to control them and the ride will be crashy as on very worn dampers.
Sportsline springs would be fine with Bilstein B8 for example or if you want more lowering you should have gone for height adjustable coilovers like Bilstein B14 or Eibach Pro street S that cost more or less the same money as FSD + springs. But if you already have FSD on order, I would go for Pro kit as maximum lowering.
