About the required upgrades for track use. Lets not forget how some people's eyes light up when telling their friends that they had all these "custom" upgrades added to their cars because they're serious track guys. I bet the dealers will like this strategy too. Get 'em in the shop with wallets open. See, it even says here in the manual that you need me to install these pricey, er, important, upgrades.
Who will win at the end of the day? Strong competition improves the breed.
