All the big tire companies I've tried in the past have failed me when it came to properly balancing tires (despite multiple trips back), and I worry that some may not have the proper equipment to jack up the M3 without breaking the mounts/loops. What's your go to shop? I'm in the bay area for anyone here (which is probably 50% of you), and looking for places to do a good job the first time, and also have the proper PS4S (with sound insulating foam).
