I've basically done that, except normalized to 1.000 for the fast time and all slower times are 1 + x.

Last year I PAX'ed 2nd in a 91 driver event, with John Heinricy PAXing 15th. Is this close enough?

since this is the biggest autocross thread...




are pylong penalties paxed? ie, pax time - cone penalty or should it be time - cone pnalty * pax?

Everywhere I've competed it is always: (raw_time + penalty) * PAX Index. The SCCA Match Tours do this as well for the portion of those events that rely on PAX Indexes.

They tend to add time when I hit a cone, instead of subtract it.

Ha, ha! Too funny! Fixed now...

Here's my run from the last El Toro event on July 20. Got a new Audio-Technica ATR3350 external mic...I love it. Mounted right above my license plate.
Also first event with OEM camber bolts installed. What a difference, feels so much more confident cornering.

Hey guys, 1st post and I had my first autox yesterday in a bone stock BRZ. I traded my 2014 Camaro 1LE for a BRZ

After the first run, I sat there and wondered how something this slow on such crap tires can be so much fun. It was the best, not fastest, car I have autox'ed. I have 215/45/17 r-s3 v2's cn order and I am going to get crash bolts to dial in a nice custom alignment. I did not read through the 60 plus pages, just here and there, but what are peoples recommendations for an aggressive c-street alignment?

Here is the video. C-Street in NNJR is filled with talented drives. I finished 4th out of 4 and was about 2-2.5 seconds off the first 3 guys who were each prepped. 2 rx-8's and a BRZ all in the 37's. Next event I plan i running with them as these tires are awful.

As much front camber as possible (which isn't much), 1/16 total toe out up front, 1/8 total toe in out back. Add good front sway bar possibly (I like Strano's)

Bingo!

The Strano bar actually made the car less pushy, shockingly enough. I have almost that exact same setup (Hankook RS3v2 in 215/45/17, Strano bar, OE crash bolts at -1.1 camber up front, 1/16 total toe out front, 1/16 total toe in rear). I've found the fronts are happy around 40psi. May need to go up a psi or two if they're rolling over. Rears I run around 34psi and almost never touch.

And if you're willing to take a little bit of advice.... A) you're not looking far enough ahead, because you almost kept slaloming at that one point Easy fix and you probably already know it.

B) You're double turning in on elements. It's one of those subconscious things that I had to break the habit of too, and I didn't even realize I was doing it until I drove a friend's M3 last year. He rode with me on one of my runs, we finished up, and he said "Dude you're turning in twice for everything. You turn in, reset the wheel a bit, then turn in again."

I went back and watched my videos, and sure enough... I was chopping at the wheel like you're doing in this. Had no clue I was ever doing it. I broke the habit of the double turn in, turned in "confidently" as he stated it... and got faster (in everything I drove).

I noticed that too at second mini slalom. I honestly don't remember doing that but it did seem like I thought for a split second that I wasn't out of the slalom yet. As for turning twice, not exactly sure what you mean as it is impossible to only turn "once" as nothing there was constant radius. Towards the end I did see myself turn in, retract and turn in and I believe that was just me guessing on how much the tires are going to roll over lol. Either way all advice is welcome and thanks! I can't wait for the next event and the kooks.

Well, that's a big change. Pretty sure I was gridded next to you at the Jersey Tour. NNJR does have a ton of good drivers, and most of them do multi-duty as instructors as well. Don't be afraid to ask for them to ride along or even instructor run your car. Carmenini in particular will be helpful if you want it to be a C-streeter, and Yatsko/Crea have all been incredibly helpful for me over the years. And not a single one of them will refuse the request if they're available.

The few "double turn-ins" that I saw looked like either the car flat didn't turn in the first time, so you backed off and tried again (not a bad idea) or that the rear felt like it was coming around, so you were trying to catch it or something. In any event, it probably would help if you put some emphasis on smoothing out your inputs, looks to me like more mid-corner corrections than you'd really want. Hard to explain, but you while you want your inputs to be quick, you don't want them jerky. Your traction circle gets a little bigger when you approach the edges, instead of just trying to run directly to (and often through) the outer limits. The best way to get to that is getting ahead on your steering, which requires looking ahead, so a need for a direction change is less of a surprise. For me, getting through a slalom quickly should be mostly about being early so you can let rhythm and muscle memory do most of the work. And you'll have some slack to work with (without needing to slow down) if you fall behind through the slalom.

The all-season tires are undoubtedly low grip. But, there might be some benefit to toughing it out for a few more events on the crap tires, just so you can work on technique a bit before putting on the stickier stuff that might mask driving mistakes. Just my opinion, but, provided you're not in the hunt for season-end trophies, why not use the rest of the season as a series of test and tunes?

Yea I was at the Jersey Tire Rack Tour. I think that was my 3rd event in the Camaro on stock tires, which simply did not work on day 2. I went from a 1.5 second lead after day one to being 6 seconds slower on the first run of day 2 lol. Thankfully the temps went up and I eeked it out on the last run.

As for Tony, he was the first guy i recognized when I took my Camaro to it's first autox. I started autoxing in 2003 and knew Tony/Jeff/Hurst/Ernie/Perry from back in those days. Chris, I have been bsing with him alot more lately and following his RX-8.

I am def not the "smoothest" driver in the world but I attribute my mistakes to driving a car that is the polar opposite of what I have been running for the past 9 events. I was surprised how early I can get on the power and how light the car felt. These two aspects of the car probably increased my jerkiness as it was "fun" lol. As for the stock tires, they are coming off and being sold. Thanks for the input and maybe we will be at the same event one day.

Awesome running with you man. I was the other BRZ at the event. I'm glad to see more people with the twins playing in CS. I was sloppy in some sections and if I had cleaned it up, I would have had a better chance chasing Konrad. We gotta take out those rx-8's. haha

Here's my video for comparison:

See you on the 24th. I should have the tires and an alignment by then.
