E46 rear end stability/rebound help
I use Pan Auto in Markham for alignments. (905) 294-8838. Might even be worth mentioning the cause for your visit when you see him in person, perhaps he can take a peek while it's on the machine.
Tell him Anuk referred you.
It's a one man show, but the guy is meticulous and by far the best and most accurate alignment shop I've used, and I've been to several and most weren't good enough or charged obscure rates. I've had several cars done there and some with custom specs to my liking. Perfect job, every single time.
