It's a gamble unfortunately. You may find the new springs elevate the ride height somewhat. I've seen that all too many times with VW springs. They never just stick to the original factory recipe with springs and dampers.
Those paint dots determine all manner of things. Production year, spring rate, ride height.....all sorts. You tend to find customers complain of bashing bumpers into kerbs etc and VW quietly increase the height accordingly. You won't know until you fit them!
I attempted to go back to OEM whilst my coilovers are off for rebuild, but through ECP and VW, there's just too much uncertainty with the spring part numbers and damper choices, so I've opted to go with the -20mm ST kit instead through DPM performance in the interim.
I was also up for the B12 Pro kit, but again, too many choices.
ST do at least seem to have their schitt together when it comes to model specific configurations.
