from neutral to the top of 3rd is 1.25". The next shot is of the JBARONE in 3rd.
Neutral is at 6.625"
3rd is at 5.375"
Difference of 1.25"
3rd is at 5.375"
Difference of 1.25"
Now the math
JSPEED
1.625 to go in to 3rd gear.
1.625 is 81.25% of 2
100%-81.25%=18.75%
1.625 is 81.25% of 2
100%-81.25%=18.75%
The JSPEED STSP reduces the throw by 18.75%
JBARONE
1.25 to go in to 3rd gear.
1.25 is 62.5% of 2
100%-62.5%=37.5%
1.25 is 62.5% of 2
100%-62.5%=37.5%
The JBARONE STSP reduces the throw by 37.5%
