They are the correct offset. No spacers. I *think* they are 27mm offset. By the way they fit in the wheel wells perfectly and there are no rubbing issues. The people at Bekkers will know the proper offset if I'm mistaken about mine.
Yes I've noticed a difference in ride & handling. The front doesn't lift during full throttle acceleration, and the rear doesn't squat and the car doesn't roll as much during cornering.
The ride is quite excellent on the highway IMO. It's very taut but not too harsh. When you do encounter pot-holes, bumps, bad expansion joints, etc you WILL feel them more ....but it goes with the territory. If you have bad roads in your area it my not be for you.
