Fiesta ST autocross accident

[PWRSRGE]

Questions for you guys The high for the day I autocrossed was 55°. So I didn’t have any temperature issues.

Popped the hood open in between runs and had the heater on the whole time. I was using both the front facing vents and the feet vents. Is it better to use all the vents or just the top ones? Which solution would get rid of heat the most?

Also, how much fuel are guys running with? 1/4 tank? 1/2 tank? I’m assuming anything in between quarter to half a tank is ok. And 1/8 or less can cause fuel cuts.

No

The most I ever manage to fit in my mkv gti was 255. Anything more would’ve required wider fender or fender flares.

Mk7s and even mk8s are common in the class and can definitely fit 265s on a 9" with the right setup, not sure if it's actually better for them to max width though. And yeah when mine was stock I had to blast the heat for longer courses in hot weather but you should be ok without when it's cooler. I usually just use the top ones and close the middle with the outside vents angled out the window. As far as fuel goes if you want to pinch pounds probably a quarter tank but I was never too worried about it.

I gave up on building a car to a class decades ago after winning a lot of events in the best car in class it got boring. All my cars since then were built to what I wanted them to be and then ran in whatever class I had to. It turned out for me that I liked this much better, especially when I would take 2nd, 3rd, 5th at a national level event in the wrong car and beat most of the right cars, far more satisfying

In the early days I had boxes of trophies and plaques and eventually donated them to be reused and never accepted another one.

Even with their superior tire/wheel width and power, aren't the Civics significantly more portly than our rides?

That’s crazy. Must be nice running 265’s. Are they running stock fenders?

Thanks for the other advice

That’s how feel now. It got old doing big builds. So I just want to be on street classes with the minimum mods possible.

The car looked solid while it was running.

Well, it finally happened - I had a big two-wheeling incident in AutoX. Grissom aeroplex, so very grippy concrete. New-to-me RE71RSs on 16s. First run on them, had a tank slapper in a chicane as the tires were warming - nothing unusual, and I don't mind getting the rear out in this car. When it swung back the other way the driver's-side tires hooked up, and up it went.

I was able to ride it out (those years of two-wheeling a four-wheeler in high school paying off? Or just lucky) on two wheels.

The passenger side came down hard. Shrugged in shock to the corner workers, and then completed the run w/o red flags.

I'm not sure of the takeaways to be honest. I'm running Koni yellows full stiff, no rear bar, and have 4 years of experience in this car. It felt like a fluke, but a sobering one at that.

This is a forum, so we'll all have our advice or theories - that's ok. And I had a great rest of the day driving (including fun rain runs!). I wouldn't dissuade anyone from running this car, but I do wish I could get the roll center down a pinch.

Pic of AI slop of my car on the corner. Like the longitudinal trans and inboard rear springs? :-O

I know that's an AI generated image, but did you really get up that far?
If so, looks like you got them beat. Congrats?

My only thoughts are maybe full stiff on the susp isn't the way. you need more pliability especially when going 10/10 on a flat surface. Just a guess though.
