How many rpm's are you turnin at 75-80 mph. Do you think it's enough gear or would you suggest 4:10's. My car is a daily driver, so that is a concern to me. Feedback is appreciated! Thanx

I was trying to decide between 3.73s, 3.90s, and 4.10s - I ended up with 3.73s.

Why?

Because I always leave my car in 'D' except on the highway, and in 3rd (D) my rpms at 60mph with 3.73s are like 2900, 3.90s put this over 3100 and 4.10s were well over 3200 or 3300.

Keep in mind I am supercharged so 3.73s were all I need, if N/A I don't know if 3.73s would be enough to get me moving quickly. 3.90s would probably be a great compromise between 3.73s and 4.10s.

Good luck

Howard

Put a 4.56 gear in it like mine.:evil: No do the 4:10 and get a chip and dyno tune.
