Thanks Gear, this makes me believe to stick with ZCP stock for the duration. I plan to do 20 days this year as well. I did about that last year, but I had another older M (non-ZCP) and upgraded the springs. That's a bit of good news on the tire wear not being that bad either, but then again you're an instructor, so your driving does help it a lot
