Here's my thought on the competition package benefits and deficits. The comp only came on 2011 and later models which had different bearing shells. The competition package had higher spring rates, slightly lower COG and wider wheels but typically EDC which may have little benefit but higher cost. When you are stuck with no camber allowances, wider wheels have more importance. Weighing that relative to running in class was a choice. You can run the same width tire on a 1/2" narrower wheel, just not as effectively. That's why picking the right car is important. Believe me, I picked the wrong car to start auto crossing and have paid for it for years.
