USDM vs. JDM STi RPM's

Hey Everyone,

I was wondering what the difference in RPM's was. Can some of you do me a favor and do a little test when you are driving next...

1st test is check the RPM's at a 65 MPH roll....in 6th gear

2nd test is a 80 MPH roll....in 6th gear

I need the results from a USDM tranny and a JDM (closer 5th and 6th) tranny...

I think I know the difference, but I wanted to varify...If you happen to remember, could you post your results??

TIA

At 65 the car is at 2500
at 80 its about 3100-3200, hard to tell where the needle actually points at
this is in my 04 sti, but I'm rolling on 245/ 45x 17.
I think its about an inch taller than the stock tires
hope this helps
