SNIP bw must have an aftermarket t5 with similar specs except for a more reasonable 0.8 5th [the svt's is 0.63, which would be great for a -6th-]. SNIP To each their own, but I see no benefit to a .8 5th, and would prefer To have the .63 for a deep over drive. Thus any building on the transmission that I would do if I felt like It would be to come up with a close ration 1st 4 gears. But so far, the stock ratio's and the deep overdrive have proven to be a very workable combination. This is using a 3.15 positraction final drive. The car cruises effortless in 5th and both practical and impractical Road speeds. Also the stock Mustang location for the shifter is perfect for what I like in my Javelin.
