Default RE: 3.90 gears?

the biggest question i have for u guys is how does the car perfom on the high way, i know i lose a few mph in terms of top speed, but i also dont want to go down the road at 65-70 doin 3,000+ rpms. Can you guys give me an example of how high the engine is reving when your goin down the high way.

Also mine is a 5 speed and spend about 1/2 the time on the high way.

thanks for the help guys!

How does that compare to an auto in o/d on the highway cruisin at 80-85? Also if you guys say about 3k rpm how the hell do you still maintain a top speed of 130+ with gears like that or even 4.10. I'm a little skeptical now and was pretty much set on 4.10's but I do take the occassional highway trip.

From what I hear... auto's should definatly get a 4.10 and a tune to strengthen the shift points.. That's pretty much a general consensus... for a manual its like 45% say 3.73, 45% say 4.10 and the minorities... 5% say 3.90 and 5% say 4.30's... haha.

Thanks for the help man. How much work does it take to run with the manuals?

I have an auto and the 4.10's are great, i would never go less than 4.10 ESPECIALLY with an auto, on the highway i think at about 70 or so (crusing speed around here) i run about 2300 rpm i really dont pay attention to it that much
