Default Calling Auto GT's with 4.10's/Question for you.

Ive done alot of research for my question and I am unable to come up with a reliable answer....

To make a long story short, the clutches in the rear of my car are going to be replaced next week. Im thinking about going from 3.73's to 4.10's. Those of you with auto's and 4.10's, can you tell me what rpm's are you spinning @ 70 mph. (Currently, my 3.73's are spinning @ 2500rpms at 70 mph. Stock 17's and stock pirelli's)

Thanks in advance for your input.

Weird, mine does 70 at 2600-2700rpms? and I still have the stock 18" Fanblades on with 235/50 tires, at 75 rpm is around 2800-2900
Not a big difference between 3.73 and 4.10 IMO

You need to remember that those numbers don't just go up by 100 or 200 or whatever rpms in the terms of engine wear and stress. They factor in like the Richter scale on earthquakes One number goes up by a factor of 10 or there abouts.

It's straight math:

2500 RPM / 3.73 x 4.10 = 2748 RPM
