Get the tko trans with the .82 5th gear. I wish I had. Fortunately it is possible to swap out the .64 for the .82. Other than that I am very happy.
Corner weighting/alignment really helps a lot too. Mine was so far out that the windshield frame rattled somewhat. The car had most of the weighton the left rear and right front before balancing. I believe it was putting undo stress diagnally through the chassis. Now that stress is gone because my car's coilovers are nicely balanced. Hey, at least that is my theory anyway. lol
