Q: Will karting help me learn to adapt to an understeering car?

Q: I am a track day guy and get out on track about 6 times a year various road course tracks. This year I switched from a modified street car to a full-on race car for track use. The race car I am driving understeers and rotates very easily. This is very different from the previous car which had a more neutral setup. Rather than start the process of adjusting the car’s setup to match what I had previously, I am trying to adjust my driving style to match the car’s setup. In order to get more comfortable driving a car with understeer, I was wondering if karting in between track events would be a good way to transition my driving style to match the car’s setup? Do you have other suggestions as to what I can practice to get more comfortable with this new setup? Thanks in advance.

Q: Will lowering tire pressures help over bumpy surfaces?

Q: “I am driving a 2000 Porsche Boxster S at Porsche Autocross events and when I drive my Boxster over a bumpy section my Traction Control comes on and slows my car. I don’t have a switch to turn off the TC. To help with traction should I lower the tire pressure? Would raising the rear spoiler help with this issue as well? The spoiler raises at 75 mph but I can raise manually.”
