Thanks for all of the advice so far... keep it coming! Never knew what those little arrows were for on the tires... I was definitely not hitting those.

Curious why some are running PTM 4 vs. PTM 5. I think PTM 5 uses stiffer suspension so it would be the best choice... I only tried PTM 3 and decided to move to 5 after 3 seemed to be way too restrictive when sliding the car a little...

Thinking I will try 35psi in the fronts and leave the rears at 32 to start with next time.
