That car is so sweet, LOL!
Actually, when I switched to my winter tires, I removed the spacers and I don't think I'll put them back on. I always had a slight shimmy up front and it was annoying. Took the spacers off and the ride is beautiful. Not sure if they were not completely hubcentric or if they were flawed somehow. And I don't mind the look without them.
And in reference to the Eibachs, it was the best decision I made. To me the change in ride quality barely exists. The New England roads are not kind, but I've had no problems at all. With other cars, I've cringed when pot holes, bumps, etc. were approaching. No such worries with the LS, with the exception of speed bumps and such. It's the most liveable lowered car I've owned. I highly recommend it.
