Looking for tips and pointers from my runs...
Hey all, I've been a member of this forum for a long time but have only recently started auto-crossing. Years ago I drifted quite a bit but that doesn't really translate to speed around a corner.
I've recorded a few of my runs and would really love some input, tips, pointers, etc... on them! This video is from my second event (I've only ever done two) and was within a half a second or so of my faster runs of the day. Places that stand out where I'm sure I can gain some time: - Around 46 seconds into the video, maybe I should have come wider sooner to get more speed through that section? - Through the longer slaloms in the beginning, should I have been more aggressive with the same line? different line? etc...? - The long sweeper at the end of the lot (half way through the run): I was attempting to keep my speed through the corner but I'm thinking I might have done better to find a way to set myself up to get back on the gas sooner in the exit. Would love input around this. - Near the end I was kinda choppy on the throttle: I'm betting if I'd been smoother I could have kept traction better for faster acceleration The car is completely stock. Thanks so much! I've already purchased an AIM Solo 2 which I'll have in the car for my next event! Last edited by flip; 07-20-2018 at 01:36 PM.. |

Question: what gear were you in for these runs? I heard some shifting, but was curious where you spent most of your time. That car has a LOT of torque so I would think you can pretty much leave it in 2nd gear the whole time except for maybe a very tight, slow corner.
Also, what settings were you using for EDC, throttle, etc.? I usually kept things in the softer settings to make the car less jumpy, and because I liked feeling a bit of the weight transfer during transitions. I'll watch the footage a few more times and see if anything jumps out.

For settings, I was using traction control completely off and suspension in the sportiest setting which is hardest. Maybe I should try loostening it up a bit? |

Do you mean DSC off? As for EDC, try different settings and see what you prefer. Your throttle inputs did sound a bit aggressive but I'm not as familiar with that motor. Did you find yourself having to hit the gas and brakes abruptly? Were you smoothly feeding throttle, brake, and steering in and out? I also noticed that your steering inputs through the slalom looked a bit jerky. Next time, try positioning the camera in a different spot so you can see your hands and feet moving. Otherwise it's tough to really provide any tips.

1) I might have been simply stabbing the throttle out of muscle memory from drifting which I am trying to stop 2) I am still working on getting to know the course and looking ahead as much as possible so I think some of them I was would get on the throttle thinking it was time but I cornered a bit off so I had to correct steering and had to let off throttle Quote:
If I smoothed out my throttle input might that alone potentially shave off a significant amount of time? Quote:

Thanks for the help! I'm getting more and more excited for my 3rd event! I'm really wishing there were more than 4 runs in these events as it's really hard to feel like I'm making progress or learning from my mistakes. I feel like I'd learn so much more if I could loop the track for a while or simply have 10+ runs... Might have to start looking for track days. |

The end or just in general looks like you are not looking ahead, you go into throttle and let off then see the next section then get back in, you should not really be off the throttle or brake at any time.
Also be more aggressive in the slaloms, you seem to be taking them slow but im not in the car so cant really help there much. But the most important is looking up, in 1 spot you got surprised by the cones. |

And yes, being smooth will be faster. It will feel slower in the car, but getting on the gas earlier and more gradually means you are spending more time accelerating. Think of it this way: if you had to keep abruptly smashing the gas pedal, that means you realized you were probably a split-second late getting back on the throttle and that you should've been accelerating by now.

It's really hard to tell without being able to look at the hands and the head (helmet), but that's my general thought as well. Just looking at the video, looks like the OP was driving from cone to cone, and not necessarily looking 2-3 TURNS ahead.
But it's really hard to make any sort of judgement from this particular view in front of a monitor.

You just need more seat time. Find an experienced driver and have them ride along and give pointers and you ride along with others. Plenty of fast guys in ATL, a few National Champs too! |

Yep, good example right there. That should've been one smooth movement of the steering wheel, unless OP felt something happening with the car and was trying to correct.

No, but I do like to talk with others and see if they have different opinions. I also take notes about each run so I can track if things are working/not working.

I do feel like taking notes would be helpful especially when I'm going back and comparing the GPS data between my runs...

Sure, but also comments about mistakes you made, how the car felt, track observations, etc.

You're doing alright for a newbie. The biggest thing is to make sure you have fun. I'll give you my input:
1. Others may not see it in the video, but that lot is really bumpy. Turning your suspension to a slightly softer setting might help out. 2. I'm not familiar with the F8x. If you can turn the power down like you can on the E9x, it might give you more freedom to modulate your throttle. 3. If you're looking for more runs and just a good community to help you out, try the local BMW CCA auto-x. They typically have 6-8 runs per event and folks are more than willing to ride along or take you for a ride to help you out. The next event is in about a month. Good luck! |

Typically the local SCCA regions run test-and-tunes and schools where you can get 40+ runs, and with instructors. You should look into doing as many of those as possible, but still go to the events with 4 runs since you'll get used to adapting more quickly. That's just part of the sport |

Like others have said, keep the car in 2nd gear. You have loads of torque, so there's no need to be shifting. If the car is completely stock, you will get a huge benefit from pulling the front camber pins and getting an alignment to max out your front camber (assuming your car has the pins like previous generations did), and it'll help wear your tires more evenly as well. Assuming your diff is similar to the E9x, it helps tremendously to apply light throttle as soon as you're off the brakes in the corner. This helps the car rotate and make it around the corner, and it will force you to be smooth with your power delivery. Not sure what settings you're using, but keep the throttle settings (power mode?) on the normal setting. Sport throttle settings make it too hard to modulate. My rule of thumb for whether to come in wide, or keep it tight is this: If the corner is 90 degrees or less, you want to make it wide so you can carry speed through it. If the corner is more than 90 degrees, like a long sweeper, you want to keep it tight to the inside in order to reduce distance, which will shave a surprising amount of speed. Hope this helps! |
