    I've been trying to pull-up specs on Grand-Am cars.
    The Mustang has been doing well on short twisty courses which has surprised a lot of people. Also decent tire and brake wear.
    Hmmmm....
    My questions are:
    Are the Porsche's and BMW's crippled with weight, displacement or restricted intake?
