What are the metal trapezoids for?
So Caltrans is doing some highway work. Could someone educate me on the name and purpose of the metal trapezoids and the thicker, longitudinal bars?
Ty in advance

Wife and I got both our flu and Covid vaccines a couple of days ago. That night we were both sore and fatigued. By the next afternoon she was mostly recovered while I improved little. This continues to be the case now at nighttime.
Does that mean my immune system sucks? Or is it overreacting?
We both eat the same diet, similar lvls of physical activity, age, etc. I’m sure there are biological factors but our case has fewer variables than most. what are some theories for one person’s faster recovery?
We all use it, but why? Density is similar to water. I guess the viscosity helps it not permeate into the soils. Are there other reasons for it?
Carbon buildup is inevitable and I’d like to check how bad it is so I can bundle it with other work that takes off the supercharger, but I don’t wanna remove the damn thing just to check. All the videos I found remove it.
But I just did a check without removing the supercharger. Only had to remove 4 torx screws and wiggle the boost pressure sensor out (circled red, 1st pic).
Stick a boroscope in there and you can see the top of the intake valve.
Well, El Nino is coming and I live in an area where lots of coastal flooding is expected. I'll probably be stacking sandbags in knee high water and wading through water waist high.
I've never worked in these conditions and i'm looking for recommendations on basewear, outerwear and any other equipment you guys think I should have before the storms hit. Department is paying for it.
Thx in advance
P.S. i'm a strong swimmer

Appreciate it , ty🙏
Thanks for the garbage 13mm bolts you sent with my brake pads Brembo. I hope those $0.30 you saved were worth me never buying your products again
We all know Audis are famous for understeering. The sports diff helps but what are techniques you can employ to take turns fast?
Someone told me that Slow in, Fast out technique is best for Audis. Braking loads your front axle which is already overloaded, so brake before the turn so you can bring the car back to balance as you take the turn.
Thoughts?
