I watched this casually last night without much thought. I just watched it again and see a lot of places you could be faster. Your driving line is pretty good overall, you're just not leveraging what your car has lots of: TORQUE. While there were some tight parts of this course that tried to balance it out, this was a "power course". Stand by while I pick your run apart.
Watch your video and follow along...
After you cleared the third slalom cone (the first one after the two with pointers) you should have been accelerating past the next two cones before slowing (tapping the brake) to set up for the tighter end of the slalom and the Chicago box. What you appear to have done is driven the slalom as if it were evenly-spaced and pretty much coasted through the whole thing. Probably a tenth or two left there. Not a lot, but some.
Coming out of the Chicago box, you're way late on the throttle. You hit it at the exit cone. Should have been on it back at the apex cone. Doesn't sound like much, but for any significant acceleration run, the earlier you start, the more speed you'll reach before having to brake... it's that max speed before braking that will cut significant time! Another tenth or two there... very likely more than that.
After the slalom, you slowed for the wiggly bit and got through there just fine. A little bit of tire noise tells us that you probably would not get through there much faster. Smooth, on line, and in control. Good.
Then the big left-right sweeper. This is the biggest place you could have used more throttle. Right at about 19-20 seconds. If you were set up to slightly late apex that cone, you could have been on the gas from there all the way through the right-hander (in your car, maybe not "full throttle" up to the right-hand apex, but at least on the gas and rolling to full throttle right before the apex) to your braking point for the turn-around. It was all about being on the right line (late apexing both the left and the right) and confident. You'd be pushing the car hard enough if you did it right that losing confidence and "chicken lifting" would have caused a spin. But, as long as you stayed in it, there was plenty of room to make it around the apex of the right-hander and clear the left side of the green double-coned gate. This was the single fastest place on course, so I'm gonna say you left at least 3/4 of a second here, probably more than a second.
Your line through the turn-around was too tight. Not a lot of people noticed, but that "pin cone" was placed one block to the left of center, so there was more room on the right than on the left. You really benefited from taking a wide entry, like 4-5 blocks (50-60') to the right. You were 2 blocks (25') to the right and sort of early-apexed the cone. A wider entry would have allowed a later apex. On the exit side, you were 3 blocks off of the grass, which means you were 2 blocks off of the cone... so, you were 50' off of the cone entering and exiting... 50' radius turn.
When I drove it, I was probably 60' off on the entry and at least 35' off on the exit... meaning my turn radius was nearly 100'. Do the math... who had more exit speed?

And that exit speed led into one of the longest straights on the course.
So, you easily lost at least another half second on the turn-around.
You did a good job of managing the "kink". But, if you'd have gotten to the right even just 3-5 feet earlier, and gotten all the way toward that wall on the right, you could have late-apexed the entry cone, carried slightly more speed through the turn, and the kicker: gotten on the gas earlier on the exit. There's at least a couple tenths there. (don't feel bad, I'm certain that this was one of the places I never got right, either)
You got through the S turns leading to the finish pretty well. Could have been faster by "staying ahead of them" a little more. Get a little wider (just a little) before the apex of each one so that you're late-apexing it, and try to hug the last cone on each of the walls. Keeping up with that through all of them would have allowed you to be on the gas earlier for the blast to the finish. And what's with the double hit of acceleration at the finish? You should have been ON IT 100%. It's those weird little lifts in odd places that cause spins! Keep "weight transfer" in mind anytime you make a significant throttle change. So, at least another half-second through the esses and the finish.
Grand total... probably on the order of 2.5 seconds you could have been faster on this course without getting too fancy, just driving a slightly different line and using the right pedal more. That would have put you in the low 53's or better.
Now you know what to do, make it happen next time!
