Hi Richard,
Yes, I currently have the caster set 5+ degrees and steering is still very light with minimal input at 80mph. I like more caster and feels good to me. You are right on front springs with the high ratio rockers, you had me switch to the 150# a while ago. The front of the car really floats nice, in a good way, and stays up well under braking.
The spec is a total momentum car and good practice for me. Like you say, with any low HP car, forces you to be smooth and drive a clean consistent line. They are sprung pretty stiff, use no bars, but they work better than you would imagine. They typically run a little faster lap time than a front running CMC car. Right now, the JBL is a lot of car for me to just run around the track with, but, I’m sure the day will come again. In the meantime I’m hammering the kart and the spec. So don’t loose faith.
Talk soon, John
PS, As you know, tires usually take more than 1/2 lap before they come in.....
