I figured I'd start a new thread about auto-x videos. Too lazy to see if any exist, and besides, it's a new year and people may have an interest. In my case, the M235i is bone stock, including the staggered PSS, brake fluid and pads. I ordered the MP diff when I bought the car, but I have no idea if it is actually on the car, as hard acceleration can produce more sideways motion than I expected.
Side note: I am eagerly awaiting a feasible camber plate solution, as I want to run more than the LCAs give.
To prevent the tires from rolling over, I increased pressures to 42 front and 40 rear to start. As the runs went on, I bled some air. My first run was sloppy and I slid all over the place. Below is my third and best run of the day. Toledo Express Airport, home to some of the finest concrete in the Midwest.
This run had me 5th out of 8 competitors in ASP (where I am planning to go once I get camber), and 5th out of 11 in F Street (where the car is currently prepped).
Video fixed.
