Re: 4:10 gears vs 4:30 gears
I almost bought a 2002 GT with 4.30 gears. Literally could spin the tires dropping the clutch in third. Was a pain in the *** to drive in traffic because it would launch itself in first or second... I went with 4.10s and love it. If you don't live around a place with tons of traffic, and/or you don't DD your car then 4.30s are a ton of fun! otherwise.. They can be a pain.
In addition, you will most likely eventually end up going with a higher torque-rated clutch, like stage two or three. That makes 4.30 gears about one hundred thousand times more difficult to handle in city and traffic driving. But like I said.. Recreational driving it's crazy fun.
Accelerate like crazy
Can even make 5th gear do a little something!
Forget about traffic driving..
MPG will be laughable.
City-speed cruising will be difficult because the RPMs will be high at 35mph and 45 mph.
You'll go through rear tires, I promise.
Slipping into gear from a stand-still will still result in car jumping forward.
I'm sure I'm missing something... But that's pretty general.
