@dsgerbc - Did you ever figure out your alignment changes?

I was driving my car yesterday and my wheel was slightly off which was new. Got home and set up the lasers, and it's the REAR that changed. One wheel toed out a bit. Haven't popped off the wheel to see what is up. But a reminder to not just look at the front end when the steering angle needed to go straight changes...

I'm not 100% sure since I've changed several things, but I *think* the issue was that the used OEM FLCA's that I used to press MPP bearings into somehow came with wrong metal bushing. The ones that sit on top of ball joints. They were somehow off OEM compliance links instead, which are hair larger.

My rear alignment was fine throughout these issues.

Looking at the weather forecast in Lincoln (pushing 40C), would you guys go for window/sunroof reflective covers or the whole car reflective cover to keep the car from boiling over while in paddock?

I have very strongly considered putting grommets into the corners of a white sheet, and hanging a few suction-cup hooks (meant to hang stuff in showers and on bathroom mirrors) around the car. The idea is I can quickly reflect most light with a $7 white sheet and $10 hooks.

I have it on good authority that having the heater on max with a <20% SOC is best for running at Lincoln. That's what I'll be doing. I swear!

FWIW, run your AC and stay cool. The slight change in batt charge will have orders of magnitude less effect compared to just being calm and in the right state of mind.

Sure, but I kinda doubt that M3's AC will be capable of cooling to comfortable levels w/o the extra help in 100F ambient and likely 110F+ in the huge field of concrete.

 

[gearchruncher]

110F is a pretty standard day in lots of the USA. The AC on a Model 3 is better than most cars since it has full performance even when the car is at idle. It will not be an issue to keep the car at 70F inside if you want, and with only 3 runs a day, as Dallas says, the SoC loss is irrelevant.

 

[dsgerbc]

the SoC loss is irrelevant.

Somehow I expect to see a good chunk the EVX field at a supercharger some time during heats 1 or 2

Just park in your air-conditioned toy hauler RV like the first couple paddock rows.

Which reminds me: where are you guys paddocked? Our club somehow made it to row 3, I'm in 3A.

Being up front is pretty nice. I got to park the RV one year in chiefs row and its great being able to jump around. Last year I was all the way in the back in the "big rig" rows past the practice course. Lots of room to but literally a mile from the action.

Electric scooter or golf cart is almost mandatory.

 

[superflyrolla]

I'm in row 6. Thought that was pretty good.

 

[The Other Dan]

Looks like I'm in row 3 as well. It says 3.1. I must be next to you!
Oh wait.... no... nope.... it says row 31. 3FU1 with a great big middle finger!
Gearcruncher is co-driving, so he and I will be way, way, way down there in the back.

Race-prepping a Tesla for Nats. Life is rough.

Couple of grid shots. 5 cars, 6 drivers. It's the largest grouping of cars/drivers for an autox at a National level autox event that I've heard of.

Good luck to the EVX grid today!

 

[MountainPass]

Good luck everyone!!!

Also…are you guys sponsored by Tire Rack? How does one get in on that?

No sponsorship, if you run a SCCA national event, you are required to run the Tire Rack sticker on your windshield with some other stickers as well.

Congrats to Ian for a nice win!
In other news, 'tire cleaning' can be quite fun.
