    NASA HPDE 4 at TWS this past weekend

    Here is a video of my best session from this past weekend at Texas World Speedway. I'm still fighting corner exit oversteer, but it makes it exciting to drive.

    Looks like fun.
    So how is the new aero front impacting the performance?

    The front is very planted. As you can see the rear is loose. I need to work on getting the rear more planted now mostly in the slower corners. It feels more planted in the higher speed corners so I think the wing is helping. Probably could use a bigger wing like the Snap-on and John George have on their cars.

    Looks to me like the car is loose overall but it shows up mostly on throttle application. I would look at more rear toe in first as it is free. Then more front spring and/ more front bar.

    The left side came unlatched during the first lap. Must not have been fully latched.

    It is the GTC-200 and the wing is -5 degrees. Gives me an AOA of about 9 degrees.

    3-link rear, so toe is fixed. Stiffening the front bar was my next adjustment.

    If you run out of adjustability in that sway bar, check out what I did to mount a NASCAR-style bar. I'd be happy to bend up another set of arms for you, if you need or want to go that route.
