My car currently has a stock ROW set up. I'm planning to put new Bilsteins HD on as the old shocks are almost gone now. The question is if I installed the Bilsteins with the stock spring, will the ride height change at all from the current setup? Can it be lower than the current setup, given that the Bilsitens selling here in the far east are the normal one that has no added thread like the one Gert sells?

If I want to lower the car to between RS and ROW sport (M030), can it be achieved using the above Bilsteins with M030 springs? Thanks.
