Last week I installed C-One(Kaaz) Final Drive(Gear).
Oem Final Gear : 4.529
C-One final Gear : 4.8

Velocity - Time Graph
Redline(OEM) : 4.529
Blueline(C-One) : 4.8



Velocity - Distance Graph
Redline(OEM) : 4.529
Blueline(C-One) : 4.8


Accelation is increased.
There are some week point but overall performace is better.
After 180km/h increase will be much more.

I think 0-1/4mile time will be shorten.


* Data form Performance Box Data Aquisition
* Not same road, I'm not sure there was incline or decline but I
remember almost flat road.
* ACT XTSS clutch set and Fidanza Aluminum flywheel were installed
when I install C-One final gear. But I think after 3rd gear there are
less infection for lightening flywheel.

It takes 3 days for complete.

What he means is that your graph looks like it show the acceleration from 3-5 gear, because 1 and 2 gear maybe a bit short to reach 120Km~75mph..
Any case looks like a good upgrade, additionally at how many RPM are you spinning at 120km (75mph) in 6th gear?

OK I'll answer my Own question, mathematically only
then later you can confirm

If you only changed your Final drive and left all the rest of the gears un touched

you may be driving at ~4000rpms at 120km(75mph)
Stock is ~3755rpms for the same speed
if you would have added to swap for the US celica 6th gear set (0.725)
you would have being driving at ~3550rpm, oh and did I mentioned a higher top end speed (if you have enough power)
