First event was a rainy mess, took 4 clicks of compression out of the front and rear to try and get the car to get some bite, and it sort of worked. This year our region combined CAM into one PAX index class as we didn't have more than 3 or 4 consistent CAMC cars and only 1 or 2 random CAMS/T cars ever showing up. Luckily driving clean saved me from my buddy Juan and his Z06 as he had me on raw time and index time, but picked up a cone on his fastest run.

With the changing conditions throughout the day we were forced to run in the 3rd and potentially wettest and slowest conditions. I was shocked at how much speed we had in some areas, but ultimately was only good enough for 18th overall on raw times with other slower cars running in conditions that were dry enough to actually generate tire squeal giving them a massive advantage. In normal events Juan, Brent, and myself are all capable of top 10 times with all 3 of us dipping into the top 5 depending on layout.

Only offseason mods were some Steeda IRS bushing lockouts. Would love to say I felt them this weekend, but with the IRS braces and locating dowels already on the car I can't say I could feel any impact yet given the low grip scenario.

I've run two events since my last update. First event was my first ever Pro-Solo where I was in P2 after the morning runs on Saturday and then the car just never went faster and I couldn't put down clean cone-free runs. When I got home I gave the car a once-over and found that the front driver's side swaybar endlink had backed off and disconnected. I assume I ran all or most of the event without the front swaybar which is why it was driving so poorly.

I was able to fix the endlink and moved the front bar to a 2/3 split to go a little stiffer up front to try and keep the car responsive and maybe transition in a little corner exit understeer without having to make a rear bar change. Showed up to the event and found a very very fast course. In the end I was hitting my 9,000rpm rev limiter in 2nd gear and with my tires that's pushing around 84mph. Car handled much better and the overall pax results show how much of a big aero/big tire/big power course this really was. Finishing 3rd on PAX and racing 1st heat before the course got cleaned up and rubbered in shows the potential in the car when it's not partially disassembled. Only 2 Miata's in the top 10 and one of those was last year's national champion in CSP.
