Today was def not in the plan, but speedsf needed help with novice instruction so I figured might as well do some more suspension tuning. It was still a good time with the track fam. Kept the sessions super short since AR1s are so bad on my car, and I don't want to drive them to the cords at Sonoma next weekend.

I may need to lower the front compression because the understeer was frustrating. Felt like front tires were skipping once the tires were loaded. The car was def more composed, so maybe that's just the tires being absolute trash. I'll probably keep these settings for Sonoma to prolong the suffering before I put CRS on. Evening out the rebound definitely helped though since I had been fighting a lot of exit oversteer.

No session 5 since I forgot to turn the gopro on.
