1st - 3.760 * 4.444 = 16.7094
2nd - 2.269 * 4.444 = 10.0834
3rd - 1.651 * 4.444 = 7.3370
4th - 1.187 * 4.444 = 5.27503
5th - 1.000 * 4.444 = 4.44400
6th - 0.843 * 4.444 = 3.74629
It's an overdrive. Some people wish for it to go even further, but NA, you will not have much power to move if you needed to.
Are you sure you're doing 8,000 rpm in 6th?

It bothers me so much that I don't think I would have purchased the car had I been more aware of it. It's really my only complaint so far, but it does feel enormous at times.

If you're really that upset with it, I hear you can get a replacement final drive

What's the use.....
My question would be what is the point of 5th?
I accelerate at an on-ramp 1,2,3 then pop into 6th for "cruise" mode. If I need to overtake, 5th ain't gonna do it, it's 4th or even 3rd, since 5th is also useless for acceleration.....

I think the real problem lies within the Diff. I think the perfect combination would be to install a 4.1:1 Diff with a shorter close ratio first gear so that you don't loose the ability to break the tires loose, yet you still lower your overal cruise RPMs.
Or, just get rid of the gears all together.
The real difference would be if the car came turbocharged, then nothing else would matter because who would care.

i think u put it in Reverse instead of 6th, cuz i once hit 8500rpm on 6th gear and it was FAST!....not safe but i did it at 3am on the middle of long *** highway with there is 18th wheelers only.

dunno if this means anything but you gotta take into account the redline differences too... ZO6 redline is 7k rpm. So just to do ratios let's say 80 in 6th for rx8 is 4500 rpms (45 x 100) and the ZO6 is at 3000 rpms (30 x 100).
45/90 would be ratio of rpms to redline for the rx8
30/70 would be ratio of rpms to redline for the ZO6
difference between those is 1/14th... it's a noticeable difference, but not as much of a problem as you make it out to be (sorry if math was wrong or irrelevant)
