Olddog Rick I am not out there trying to get killed or burn the car to the ground. It took me 20+ years of saving change to get my car.
I have the first appleton power rack in an ERA car. It works great. I go to R&G for the people and fun. Every year I seam to help 2-3 keep there cars running. I don't know if your car rolls in a turn or stays flat. The spring info was just to help improve the car's driving experience. I don't get crazy on the autocourse, 120 mph is fast enough for me. With $60G in the car, I am not looking for wall paint.
I have run 15" tires and race 17" tires. The handling of the car is totally different. 15" roll and the 17" are like slicks. Good Luck, happy holidays.Rick
