ya you lucked out with 2.73's like me. I don't even know why they put these in our cars, because even with 3.23's i know people are still getting mid 20's gas mileage. I guess theoretically being able to go 300 mph with the 2.73 gears is cool.......

300mph is not happening

with 28" tires,spinning to 7000rpm and 0.62 6th gear is about 340kmh or 212mph

Are you spinning in the cold like it is now? I highly doubt you can spin at 35 in decent weather

LOL your kidding me right? 300MPH would be a serious deal if a car could do that stock. Even supercars dont pull that off.

I am set up with the exact same setup as you, same tires and all, but mine is tuned with a CAI and stat (not much more power, but still), and mine wont spin over 15-20 mph in 40* weather...

I'll believe you if you say you can spin at those speeds, but I don't think those kumho's are up to par. How much tread is left on those things? I had 2.73s with CAI and full exhaust but couldn't spin from ANY speed. That was with the stock wheels on Eagles and also on my ZR1s with Hankooks.

kumhos are good when new, but when you get about 3/4 to 1/2 tread they really suck.

I went through 2 sets before getting my Gforce kdw's
