You're looking at increasing the Toe In part of the tune, this makes for exceptional drifting and better cornering, might be good to get into your car and start fresh, play around with the toe in feature, to see what meets your needs/requirements, once you're happy you can fine tune the rest yourself, so you can fully edit your tune rather than use a locked one.
As for OP, I haven't had a chance to buy half of those cars yet as I'm still new to Forza 6, but I'll be sure to give them a go and drop you some feedback!
I'm a fine tuner myself, but don't upload my tunes normally.
