I have the TKO with 2.87 first/.64 OD, with 3.89 rear and 255 60 15 tires. First gear is a bit much and someday I plan a change maybe to a 3.50 rear. The .64 OD is perfect with the current rear gear though cruising 70 mph at about 2200 rpm
I assume you've seen this new TKX in the sales section? It has the it is the 2.87/.81 combo: http://forums.maxperformanceinc.com/...d.php?t=866159
