I just had the fixed plates installed yesterday, Bay Bridge Motors in Oakland did the install, and the first thing I noticed was a bit more resistance, more positive feeling or road feel, in the steering and I think that's a good thing.

The other change is the ride, without a doubt it is a more compliant ride. It's my understanding that the bushing material, from BMW, is denser but more absorbent in nature which results in less harshness in the overall ride.

In other words the stock 17 inch run-flats, also known as run-bricks, seem to be noticeably smoother and I'm quite pleased about that!

I also want to highly recommend Bay Bridge Motors to all that are in the area for normal maintenance or specialty work. They're a body shop as well. They are a great bunch of people that really do care about their work and their customers.

Hope this helps...
