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.

Great stuff, thanks for posting. My favorite parts are where the needle hits 140!

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.

was the hood unlatched???

What angle is the GTC300 at?

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.

I really enjoyed the video.

Thanks for posting it.

Great video, always nice to get a bit of feel for being on the track.

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.
