THE best overall rear end tremec combonation IMHO is the TKO with road race third and .83 fifth combined with a 3.08 final rear end for the following reasons. first gear with it's 3.27 ratio will give you a 10 to 1 ratio which is perfect for launching with less wheel spin and not over reving then you will really love what 2nd and 3rd will do for you because you will be right in the sweet spot of engine power band then in 4th at 60 mph you will be in they area of 2400 or 2000 in 5th if you are so inclined or your engine does not resent or protest being that low and finally in 5th at 70 which is a acceptable hiway speed you will be in the vicinity of 2300 sweet it does not get any better than that mind you this was calculated with 295 50 15s and will mostly apply to engines making the vast majority of torque under 5000 rpm which is typical for a street stip road race autox weekend warrior ect
