May as well save your self a bunch of money and stick a ST-10 in the car with a 3.42 first gear ratio, stick a 2.73 rear out back, and do essentially the same thing for a whole lot less.

I just got tired of the significant drop between 4th and 5th with the .64 OD. Anything between 70 and 80 felt like ‘no mans land’ where 4th was spinning faster than I cared for and .64 od felt soft. Not trying to start an argument here. Just saying what worked for me. P.S. - How big is the drop between gears with the ST-10 If 1st Gear is 3.42? The gear spread with the TKO 6 is quite a bit more functional and a 2.64 final drive in 5th is still a bit calmer than 1:1 with a 2.73 out back.

The difference is only 3 mph at the same rpm. So you're essentially doing the same thing.
