Sort of. Picked up a set of K.A.W. lowering springs on ebay. Haven't arrived yet. They're made in Germany, and lower the car 60 mm in front and 20 mm in the back. That's a bit lower than the usual H&R or Eibach. Supposed to be a bit stiffer too.
Other than that, I've got almost everything from my old car in my garage. Never enough time for these sorts of things.
