If you don't want to break anymore parts, I suggest you put in a widely cut Parma 3"x8" foam bumper in addition to the AE bumper pad ! As far as handling try at least once to run 42shore tires on the left side of the car and 37shore on the right side ! It stops the car from sliding too much, and reduces tire wear ! Also, bring your radio throttle acceleration or speed up to about 60%; it should make your engine pickup faster after a turn .......
