I'm still going back and forth...
here's what I'm looking at 6 speed manual.
do you think 3475 rpms will kill my engine at highway speeds for several hours.. I usually run 75-80 mph...
is 169 rpms at 85mph.. that big of a difference I should care??
with 4:88's
65mph @ 2527rpm
75mph @ 2916rpm
85Mph @ 3305rpm
5.13's
65mph @ 2657rpm
75mph @ 3066rpm
85mph @ 3474rpm

The 3.8L engine likes to rev and with these gears, your engine will really come to life. If you had an auto, this is really the only way to go IMHO even with 35's. Granted, your MPG will suffer a bit but I got to thinking... did I really buy this thing for it's MPG?
Seriously, if you're even considering it, I'd do it.
Thanks again Mel for all your help and great service!!

Ummm, well..... I have a 6-speed and I just went with 5.13's and I'm so glad that I did - Man, do I ever have power now

lol well you did it now...I had to go and order another set of gears (5.13's) and will be sending the 4.88's back when they get here. I ordered 5.13's initially, and the sales guy on the phone talked me into the 4.88's. That's what I get for letting him change my mind.
