Did a little bit of club racing this evening and tried a few things on the PRB10R. I felt overall the car was much better with the changes. It was easier to drive and more consistent. Still a few little issues I need to work on but over all. Much better

Went to a 3 hole piston setup (similar to Jason porters 3 hole shock setup). Car lands and drives better imo

Added 1.5mm of shims between the front wheel and the axle. Really helped smooth the car out.

Do not go off the manual for rear toe angles. It’s way off. With pills out on the fr block. And pills in on the rr block. It’s 0 toe oh a Hudy setup station. I did not measure fr pills out and rr pills centered, but my guess is around 1 degree of toe in. I will check those angles on Saturday.

Front end. The chassis kick up plate is 25*. The arm mount is +3 degrees. Giving 28* of kick up. The +3 castor blocks coupled with the 28+ kick up gives 31* of caster. I feel the car needs a 0* castor block. 31* is way too much.

But. In closing. The car is coming along and getting better. I’m very pleased with it.
