I would make my street rides more fun, yeah, but mainly the track days.
I've seen some posts about shorter final drive ratio, but none about the gearbox.
Is it too expensive to do that? Change the 5 gears of the gearbox?
That would lead me to the other option, which is changing the final drive ratio.
I've been watching some videos, and the 4.10 seems to be not enough for what I expect. The 4.44 is quite that.
This is a 4.44 final drive:
Compare to my stock 3.85 final drive:
I can't help beeing amazed for the 4.44. Those gears fit so perfectly.
But fuck, the 4.44 is $2k more expensive than the 4.10. But whatever, I would pay.
6th gear will be shortened too, I know, but I can stand it, as we don't have any road here in Brazil which is allowed to travel above 75mph, and I'm not a final speed lover. But in the track I want to have all the gears in the optimum torque band.
And on the street, I want to spin the rear wheels anywhere. 
Well, cut the talking.
What would be more expensive? Gearbox ou differential? |
Ok, ignore all that bullshit you just wrote about cost, and which is better, and can you do a gear box ratio upgrade, blah blah blah.
The real question is: have you done the math and the calculations on trans ratios vs. 4.44 gearing?
Go run rpm vs gearing calculations and do you think you can live with that?
