I have 3.90s with a z spec t5 (2.95 first and .68 OD) it feels nice. dont have to shift out of 1st as easily. and the OD is a tad better cant really tell.
the first gears does help a bit with tirespin on the street.
i was considering a downgrade to 3.55s but i duno i think i will stick with my 3.90s. It puts me right at 5200 in 4th at the traps at the track. which i like
3.90s fo life foo!
