Hello,
You guys are getting excited over nothing.
ALL manufacturers, Audi, BMW, MB etc. have dozens of spring/damper combinations and this goes WAY back to cars like my dad's 1954 170DS.
Tropical spec shock absorbers, anyone?
Sounds like they probably added an extra coat of paint
I got *RALLYE* spec springs for an Opel Manta A from Russelsheim about fifteen years ago, the car was very low at the front and harsh(ridding on the bump stops). The springs were shorter but stiffer and the ride was transformed and no more skipping sideways over mid corner bumps. Of course, it had Bilstein Sports dampers all around to keep all four tyres glued to the tarmac.
