Perhaps you could let us know a little more about the turning difficulties you're having here?
I've used the Minolta Toyota at the Super Speedway, which has much tighter turns than the "Test Curse" (deliberate typo

) and it seems to turn perfectly well.
Are you using the Analogue sticks for steering or the D-pad buttons, as this may explain a little? 💡
Personally I'd played GT1, 2 & 3 using the controller, mashing the D-pad because I couldn't get used to the sticks. Steering in those previous games required you to correct direction after you'd steered, i.e. if you turned sharp left, you'd have to tap the right turn a few times afterwards to straighten up or you'd keep going left!
In GT4, the steering seems more like real life, where if you stop turning the wheels, they drift back to centre. Seeing as I was used to the correction technique from the old games, it became habit, and makes it more-or-less impossible for me to drive GT4 with the controller as I try to make the corrections with the controller that the game is already making for me, and very erratic driving ensues! (Ask anyone at SFGTP2 who saw me drive a Triumph Spitfire with a DS2!

) This is probably where your problem lies too, but I'm not sure how one would set up a car to compensate for this.
I can't really offer any more advice on controller driving in GT4 though as I pretty much went out and bought a wheel immediately after my first GT4 experiences, and haven't looked back since.
