Good thought but I highly doubt it will work. I don't really know of any Genesis sedan parts that work on the coupe
Arkansas is AR foo lol
I have a 2.0t premo, but it came with a lsd already. Got one of the odd ball cars
Higher number final drive = X.XX number of input rotation to 1 axel rotation.
So for you wanting a higher final drive it would mean, more torque, BUT lower top speed, more shifting at lower speeds, and loosing gas milage (higher RPM at the same speed, compared to the stock setup).
Lower final drive, would mean that I loose torque but gain everything else. Torque can always be added with more power later.
