I agree some nice Lower Control Arms will be a improvement and a key part to get the power to the road.
I wonder what is the operation temperature of those tires?
I ask because my Eagle F1's Supercar tires do not like temps below 50 degrees, the compound really likes the warmer temperatures.
So I say this since your in Alaska and wondering if that could be a factor?
On that day the temp was around 60-65 degrees. I have the Mickey Thompson tires. I had only driven around two miles when I gave it a little gas
As I continued to drive the grip was much better. I still will look into getting some control arms.
