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...

Tony, before u machined down your volvo's brake rotor, did you get vibration when u braked or while travelling at speeds ?
I did have a front caliper that was stuck, had to get the both front calipers rebuilt, so that rotor was noticable uneven, although since the rebuild, the rotor is physically more even now. But no vibrations when braking even before the rebuild, just that the car wouldn't slide down the slight slope down my driveway.
Both front rotors are at about 22 mm so are due for replacements, the pads are almost brand new though... ha ha, prev owner just changed the pads and did not replace the rotors. The rotors are VERY pricey here from the AD here.
The "old" pads are original porsche items, can I re-use them ? Any way to "flatten" them ? There's still at least 90% left.
Although for this time, I'm going to use my new Textar pads with the new zimmerman rotors, since I'm trying to solve this vibration issue !
