nope. To my knowledge, s5 man. verts came with 4.1, auto of any kind, any series came with 3.9. s4 verts came with a 3.9 nomatter what the transmission was. 4.3 gears only came in a GTUs, I've seen them for sale for $400+ brandnew. I'd always figure If I were to pay $400+ dollars for a new gear set, it'd be a 4.50

That would be about the most difficult way to do it.
No auto FC is going to have a 4.3:1 diff unless someone has swapped one in. The easy way to check it to jack up the rear of the car and turn the driveshaft by hand. Count the number of driveshaft revolutions it takes to turn the wheels around once. A 3.9:1 diff won't quite make four turns, a 4.1:1 will make just over four turns and a 4.3:1 diff will make about four and a third turns.
