Is the ride better now with the lower pressures?
You should feel it being a bit smoother over bumps.
Also, with that much pressure in the fronts you probably had a bit of under steer, though you may not have noticed unless you're driving it harder on twisty roads.

As I've said my S001 RFT's are great, no vibes.
But, I do have a very slight vibe with the steering wheel moving left/right only after sitting over night and the tire has "flat spotted" a bit. After a few minutes of driving it smooths out perfectly.
This happened with my 135i on Conti tires, and my A4 with Bridgestones.

Do you notice a greater than usual vibration at the wheel when the tires are cold from sitting over night, and does the vibration reduce a bit after 5-10 minutes of driving?
