I have found out the my 3.70 gears with my T5 are almost useless but the 1st gear on a T56 would make them perfect. With the T5 it seems like after I stop at red lights I have to shift into 2nd before I even get out of the intersection. You may want to give them some thought or 3.89. I agree with Tad on the 4.30's. The novelty will wear off when the credit card to the tire shop starts going up.

 

Nice, LOL... I have 3.90's and a C4 in the car now.
