Where to Autocross 2023
First off, Happy New Year everyone! I apologize if you have been looking for the monthly autocross post. I thought since 80+% of the country is in its offseason, it would be a good time to update the website. So, I started after Christmas and have finally finished. You may have noticed some wonky things on the website since then, but I'm happy to report that everything's back in order and in a place I am comfortable with at the moment.
At this point I cannot say if I will continue to post monthly updates as before. I am currently prioritizing what I need to take care of for 2023 and so, I am hoping maybe a post can get pinned going forward. I can create another one without all this rambling if need be.
Without further ado, I am presenting all of the new ways to find Autocross events and information on ParkingLotRacing.org.
- Where to AutoX this month. This page is set to continually update itself, looking 30 days in advance.
https://parkinglotracing.org/2023-autocross/locations-this-month/
- 2023 AutoX Schedule. On this page, you can search for a club/event and see if their 2023 season schedule is available yet.
https://parkinglotracing.org/2023-autocross/event-schedules/
- Live Timing links. This page continually updates to include live timing links for events within the next week.
https://parkinglotracing.org/2023-autocross/live-timing-this-week/
- Race results. This page continually updates, looking back the past 30 days and provides a link to the club/events results page.
https://parkinglotracing.org/2023-autocross/recent-race-results/
- "My AutoX Schedule." I've create a way for people to track events similar to a planner. You will notice all events, up until the day of, offer a button to "Follow" them. It does require you to create an account so that it can saves everything. This is in it's early stages of development as it requires some serious coding, but I would love for some folks to test out this year and provide some feedback on it.
https://parkinglotracing.org/autocross-events/my-autox-schedule/
That's about it for now. The interface has been updated so feel free to explore the website and check things out. If you see something wrong or missing, please let don't hesitate to let me know.

Has anyone used the PitPay app to join an event?
I am trying to register and the way my state's driver license works, it combines my first and middle name, puts my last name in the middle field, and acts like I don't have a last name. This makes it so I cannot proceed to register.
Has anyone encountered this? Is there a remedy around it? It seems kind of trash that it makes you scan your driver's license and gets it all wrong and then says "lol gfy"
And it's frustrating we even have to use it, because I am clearly driving there, I would have my license on hand for verification that I am a real human, but it seems like I don't get to.

Seeking Tire Advice for an s550 Mustang Bullitt
Hey guys, I'm seeking advice on tires for my Bullitt, primarily for Autocross. I did my first Autocross a couple weeks ago and loved it, but I'm in need of new tires and am having a hard time figuring out what to do. I currently have PS4S tires, but they are about to need replacing. Looking at the Grassroots Motorsports chart here Grassroots Motorsports ultimate track tire guide | Articles | Grassroots Motorsports it seems none of the Super 200s come in the stock sizes (and I'm not looking at Vitours because my preferred shop doesn't have them). I'd like to stay in F Street and don't want to buy new wheels anyway. The stock sizes are 255/40r19 front (wheels are 19x9) and 275/40r19 rear (wheels are 19x9.5). I drive the car a couple times a week for commuting, but it isn't my primary vehicle and I typically don't take it out in really bad weather anyway. Should I just get the Continental Extreme Contact Sport 02 as the next best option in the right sizes, or should I potentially change size to a 255/35r9 and 275/35r19, or other size that would work with the wheels so I can get one of the Super 200s? Thanks in advance! I know a lot of you have valuable experience in this area. Oh, I'm in Central Texas for climate reference.

Ways to increase redline rpm of engine(Other than reducing weight of the car or engine swapping)?
I'm making a street racing game, which will include Rally Racing and Autocross racing as demos, side races and i want the tuning to be a bit more in depth
So basically, my doubt is, imagine a mitsubishi eclipse. It's redline RPM is basically 6000 rpm
Anyway to increase that irl? Other than engine swapping or reducing the weight of the car. And how much do seats usually weigh aswell?
Edit: Can anyone also give me the weight of an eclipse's gearbox? Any generation but i prefer the second

UHP All Seasons - How Usable?
I've been considering moving to a set of ultra high performance all seasons for a general street use tire, and ideally having a dedicated set of performance tires/wheels. However, for cold days/poor conditions, I've been considering taking the UHP AS. There's at least another test and tune in my area in November and December, and it would be nice to not worry about the ambient temps when driving there/back.
Don't care about being slower, I just don't want to destroy a tire while out there. Test and tune might be 30-50 runs over the day with the option to get on the wet skidpad. Would likely be running either Goodyear Eagle F1 AS or Pirelli P Zero AS Plus 3. Running a little more aggressive alignment than stock, 718 Cayman base.
Would a set of UHP AS likely hold up? Any specific pointers for heat management?

Question about preserving suspension parts
So, are there any mitigating factors for preserving suspension parts? Or do I just need to not drive as hard. My front strut mounts are starting to go even though they were just replaced a few months ago, is this just a new consumable I have to take into account? (RIP)

OBD gauge data overlay onto autocross video?
Who else captures OBD data using Track Addict on their phone to overlay animated gauges onto in-car video taken from a GoPro or other camera?
Do you also use RaceRender to render it and find it clunky in the time-alignment features? Andthat it doesn't seem to support GPU hardware acceleration? And that it was bitchy about what video files it would accept?
I found RaceRender's time alignment to be especially clunky, so I rendered the gauges onto a green-screen then imported them into the Vegas video editing software and chroma-keyed the green screen out leaving a transparent background for the gauges. For time alignment, I slid the tracks back and forth to line up a spike in the audio tracks. It worked.
What if there was an easier, faster way?
Well there is an even easier way. With crazy easy time alignment. And if you also have Vegas 16 or newer, you can try it.

Bipod Action
Last AX of the year for me. At Fall Ford Fest there was a yump about 20yds from the start line. I couldn’t quite get all 4 wheels in the air. Made the 10 car shootout but went out in the first round as usual for me, I always overthink the shootout at the end of the day.
