I usually run 2-3 PSI lower in the rear.

With the 660's, I did 32/30 initially and ran the large part of last year thinking that was ideal. With any new tire, I do the standard chalk or look at wear in the fronts, get it to the triangles, then adjust the rear to suit it.

Had a few people think I was nuts running them that low when I mentioned it. Tried 37/35. Instantly had more grip and everything just felt better. Times slightly improved, but definitely did.

Same tire size, wheel size, class, etc.

I've since switched to A052's again as I didn't like the way the 660's heat cycled over the year, but I'd definitely recommend higher at about 37/35 with those. It made a noticeable difference for me.

We went to a new site this past weekend right in Raleigh, 15 minute drive from me, and where the Hurricanes and NC State teams play. Brought in almost 150 people to the event when normally 100 is a good turnout. Took home top Pax, and 2nd raw to an AMod FSAE car brought by the NC State motorsports club.

First event in the STX car. It did well, didn't do anything weird and think I was 3rd of 90ish. A well driven kart and Camaro are hard to compete with on a power favored course.


This site is unlike any others with the banking and speeds, so I'm still unsure of the balance. It was understeery on the banking and a little tail happy on the flatter parts, but I was in 3rd the entire time, so can't really come away with any real thoughts until I drive a more normal site. But the car didn't break, so a good shakedown in my books

2nd time out with my 23. 1st time with my stx setup from my 2016, coilovers, wheels/tires and front swaybar.


Looking at the video now I think I should have stayed wider on the last left hander to get back on the gas quicker. The extra power from the fa24 is a welcome change.

Final event this year.

The slower part of the right course I found time by downshifting after my camera died. Any other tips and pointers welcome. This was my first AutoX in 20 years lol

First event of the year, first time at ZMax in this car, and with the much softer spring rates and softer rear bar. I turned stabilization on in the camera at some point in the off season, so the video kinda sucks.



The run was solid, felt I could have cleaned things up here and there, but overall it was a good run. Still have some adjustments to make before I'm totally happy with the car. Ended up 5th PAX out of 203, and about 4 tenths behind Mudge. Hopefully that difference continues to fall as I get more comfortable in the car and settle on a setup.

It's been about 4.5 months, but we're back at it here in PA. Just a test and tune. Our real events have another month to kick back in.

Fastest time of the day because the faster people didn't show up.

I beat an S2000 by .5 second and an NSX was 3rd.

I'm still struggling to get an angle that I like for the video. Suggestions on GoPro mount points?

Just suction cup it to the driver's side rear window near the bottom, at a right angle. You should be able to get it so it can see the driver, the front left wheel, and the course in front of the car.

still too cold here and we're not autocrossing yet but here's one of my videos from last year to see what it looks like

Made the 8 hour trek to Moultrie, GA for the SCCA Solo National Tour. Day 1 I would define as steady. Not a bad run, but left a fair bit of time on the table, and thus dug a 6 tenths hole on day one. Day 2, was a pretty good run, and just about made up all but 0.042 the 6 tenths. Went way wide at the beginning, but other than that it felt really good. Still brought home a trophy, and ended up 13th in PAX, so not a bad result for my efforts.

Either behind driver side door as mentioned above and used in many videos posted here or get a headrest mount and put it in the center just behind the driver. Location needs to be consistent when comparing runs - no helmet cam unless it’s for the ‘gram. You need to see where your head is pointed to identify any issues with your vision which takes out most exterior views and the right side. And you need to see your hands on the steering wheel to identify any issues there. Mounting on the rear window doesn’t give enough view of the track/course imho so there’s really only two options in my book for your primary camera.

Views looking from behind the sunroof so you can see the course as well as the driver are the best, but not an option here. Here’s my latest run that doesn’t totally suck with the center view. Amazon GoPro head rest mount and something decent will come up for $40.
