Atlanta 5 points solo

This was my third event and my fastest time of 65.332. Some other guy I road with in a dropped Speed3 was only getting like 64.5ish
any comments on how I could have improved?

I looked to me like you were a bit late and tentative with your steering inputs, a little light on the throttle in places where you could have been wide open, and a little late getting back on the throttle after turns. I suspect it's all due to not looking ahead on course enough. Overall though you look pretty good. You line seems mostly right, except for entering a couple of those 180 degree turns really tight. It's hard to tell much more than that without seeing your steering inputs in the video.

Next time try to focus on looking ahead, and getting on the power earlier in turns. In order to get on the power earlier, you will need to brake more aggressively whenever you brake so that you enter turns slower. Being slow into the turn helps you go fast because your real goal is to get back on the power as soon as possible.

If you have a sunroof, try mounting the camera hanging downwards from the glass inside the car, like this:

Otherwise, I like to put it on the window of the drivers side back door, so you can see your steering wheel along with the course, like this:


Mounting it inside the car helps to make the motor noise audible over the wind noise, which is helpful in figuring out when your are on the gas.

Nice runs.. .That's why these guys that are dropping their speeds without proper valving/struts/coils are doing nothing but hurting their car.

You have a RSB yet? What tires are you running? Stiffer sidewalls have always helped me.

This all depends on how much his front end is/will dive. My 2

Obviously the exact amount of brakes to apply will depend on car set up, but the concept of "in slow, out fast" is pretty well established. No amount of dive will change that. In this case, I autocross a 3 at stock ride height very competitively, so I've got a good basis for comparison.

I do have a video with the camera mounted on the inside I'll post that one in a few but they weren't as fast and a few creamed cones.

The 180 turns did give me the worst trouble. there was a lot of under steer. I feel like I was on power too early causing the under steer. How should I have taken the first tight 180 turn? (00:47)

On the 2nd optional slalom I entered on the wrong side due to improper entry of the wide long turn.

Nvm on the pov view of the course, the video was compromised...

I also felt like my tire pressures were off. front 49 and rear 37 on RS-3. this is also the first time running with the Hotchkis rsb (soft)

If you were understeering in the 180, that almost certainly means you were going in to the turn too fast. Brake harder and/or earlier. As for how you entered it, I could suggest a different line, but I can't be sure my suggestion would actually be an improvement without testing it on course. Fixing the understeer issue with more brake application would be a much bigger time improvement than any line issues anyway, since the line you took wasn't really that bad.

If I were to make a suggestion I'd say you should have turned earlier going through left through gate right before the 180, so that you could begin turning right before the 180 gate and thus widen your turn a bit. You could also have come closer to the cone at the outside of the curve as you exit the 180. This would add some length, but let you keep some speed. Whether it actually works out to be faster nobody can really know without trying it.

I've never driven RS-3's, so I can offer much advice there. I would suggest chalking your sidewalls to see how far down on the sidewall you are rolling. Ideally you would use all of the tread face and maybe just touch the sidewall, but tire chalking is a very rough guide, and it still varies tire to tire. The best thing is to make it to a test and tune event to really dial in tire pressures on a skidpad. If you don't have such an opportunity, you'll just have to experiment and see what feels best.

I'd also turn that sway bar up. If you're still getting understeer, and you don't feel like the car is becoming more tail happy than you like, there is generally no reason to hold back.
