      That actually doesn't look too bad. I wonder if it stays like that in dive and roll?

      If the fronts are staying like that mid turn (in dive\roll), the next thing I'd be trying is a way to get the car to release the inside rear between turn in and apex. With a watts maybe lower the rear roll center so the body has a bigger lever to push with or if adjustable sway bar maybe stiffen it up some? My weapon of choice is generally more rear rebound on the shock to accomplish this.

      Actually, scratch that... I'd need to see video of what the rear and front tires are doing while turning each direction before deciding on what changes to make. Seeing that it seems to turn left much better than turn right, a wedge or cross weight adjustment may help more.

      How often do you take a passenger on runs with you? I'm betting on a right turn favoring course like the above, a passenger would net you at least a second if not more off your lap times. I once ran a very similar course on that pad at an optima event and having a passenger bumped me up enough to get my name listed on TV in the autocross results.



      Geez, my car pushed SO bad back then!!

      Raising the rear RC and stiffening the rear ARB both make the rear stiffer. Unfortunately, my rear bar is at full stiff right now. I never like to be at the edge of the adjustment range but it'll have to be there until I can figure out something else. The car would definitely benefit from more low speed damping force, especially in the rear. Double adjustable varishocks are on the list for upgrades, hopefully soon. I am very happy with my current varishocks, they just don't have quite enough damping force.

      I very often have friends as passengers. I used to be like you and go faster with the better right/left weight distribution, but have found in the last year that I go 3 to 6 tenths faster on average without the extra weight. Very interesting. Some things I guess we'll never understand

      Pretty good driving in the video. Smooth and deliberate. I need to be more like that, although I think it will come. So far I haven't even gone to two events in a row with the same setup in the car. Once I learn the car again I think I'll get to a point where I can trust it more.

      Thanks... In 2014 I changed the complete suspension setup in my car 3 times during the racing season, and still won a Regional Championship, so I get the different car every time at the track deal.

      Here is a video from the last autocross event I ran back in February just to show the difference between back in 2015 and today in both driver and car ability.



      Many different iterations between then and today but just to show with a bit of time and knowledge, you can adjust the car to work well with your style of racing.
