When I bought my GTi, it had a set of Tokico Blues on OEM springs. I mounted a set of 336 lb/in springs with about 1" of drop and within a year they were worn out. I moved on to the AGX adjustables and kept those damper for another 4 years.

Find the spring rate of those Vogtland springs; if it matches the GR-2 damper range, you'll be fine.
