i have a volvo and the front passenger rotor had to be machined down because - i don't know something - but before that there was a really bad vibration, afterwards it disappeared.

also, you have to get roadforce balancing. i had the tires rebalanced and the shop didn't use the roadforce balance. i made it about 3 miles away before i turned around and made them do it right. night and day difference.

the boxster is so keen to what the road is doing, the tires, brakes, etc. that anything off could make a difference...
