Hi,
A friend of mine had a set of these on a late 90's BMW 5 Series, raved about them when he bought them at how cheap they were but they failed pretty quickly, replaced and failed again what failed I am not sure but it ended up with him swapping back to the original BMW items.
A cheap way to lower a 202 is to replace the rubber shims (fitted on top of the springs) these are manufactured in varying thicknesses according to what model/spec the car is if you have the thicker ones then by replacing with the thinner ones you can lower it quite a lot up to 18mm , depending on what was fitted from the factory.
Also if you are running 18" AMG 210 E55 Wheels then be careful how much you lower the front as you "could" start fouling the front arches especially if you running 210 size tyres.
