Did lots of stupid small projects on the M3 this weekend that I've been putting off for way too long....
Put a gasket between the fan and the radiator
Tweaked the rear preload
Installed the CSL rear sway (front went in a while back)
Properly mounted my lithium ion battery
Went to an intake duct for the CSL intake that isn't (literally) a piece of gutter)
Replaced a brake line that showed a little surface marring
Bled the brakes
Replaced the clamps on the CSL airbox with ones that can expand (OE BMW) instead of the screw types, so the trumpets don't get damaged as the box heats up and expands.
Ate my free bimmerworld gummy bears
Replaced the shift knob with a new one (old one was showing signs of wear).
Installed the homelink in the no sunroof headliner
Put BMW center caps on the M5's just refinished in BMW Chrome shadow BBS RG-Rs (M5 is still at the body shop).
