Cheap tires and brake adjustments is pretty much all you need to pull off a drift. Real life that is. Anyway for this game no. Just turn off the ASM and TCS.
..Not to sound mean or anything, but...
1) Do you know what the **** an intercooler does?
2) If you answered yes to Number 1, why would you need one to drift? Sure it may help a bit, but I'd say it's far from nessecary.
just reply to the question people like sheron... u don't need any of that other negative comment...you all act like know-it-alls... just answer the question----> and no u don't need an intercooler...that's for a turbo HP raise----> nothing for chasis or anything nor tires
