Technically, yes alignment for every time I change tires, wet vs dry, hot vs cold, click the JRZs. But practically, no. Alignment stays the same between track days.

ACM is finishing up Turner solid subframe bushings and do88 DCT oil cooler because the car is already in the shop. Then figuring out the alignment.

We did corner weight balancing for the 2019 track season. But to corner weight balance 3500Lbs requires to much hight differences.

So I am prioritizing hight vs weight. We are dropping the front 5mm and evening out the hight left to right. Then focusing in the rake.

The results will be somewhat a lower car, with preliminary checking before the bushings were installed shows 5mm.

We also took a better ratio measurements between the shock travel and the pots travel

The front travel is shock : potentiometer 2.86:1
the rear is 1.04:1

So once programmed into the math channel of the EVO5 we will have an accurate shock travel in the cockpit and on lap traces.

AIM has "Suspension" analysis and flipping to "advance" allows me to see mm/sec. At the NYST best lap on Hoosier I was getting to 400mm/sec that I am waiting to hear back from JRZ what should be a starting point. Is it too fast? too slow?

It looks like the fronts are good, but the rear rebound is too fast. This topic will get more attention in 2020.

Can't wait to get aligment results from ACM on Tue.
