well finally got the disc break 3.23's rear in...and so fare I really like the 3.23's over the 3.73's. I like the fact that I can do about 45mph at 2000rpm's, then dump it into 2nd where the rpms goes right into my power band (3300-3500), vs the 3.73's where it would put me at about 4100...no track results yet, but I'd say the car feels the same way, just act like it has one extra gear, I barely hit OD now downtown, and also I belive that the speedo is geared right too (I'll have to check)...it just feels like the hole car is more "in tune"...I still brake loose first and part 2nd...hehe...I'll post some track time asap.

pondering a similar swap, from 3.73 to 3.42 or 3.23. The 3.73's put me out of my power band in the traps, plus i'd like better highway milage.
Can't wait to see those times!
Good luck.
