GXP vs Monte/Impala SS Everyone goes on and on about how the drivetrain is the same between the 3. That the only difference is Tapshift, stabilitrak, suspension etc. But the drivetrain is different. The GXP has a final drive of 2.93.1 and the Monte/Impala have a final drive of 3.29:1. as per http://www.gmcanada.com
Is this a big enough difference to feel? Do the chevys spin more? Launch harder?
What's everyone's opinions on this? Especially those who have driven both.

Hello everyone, I just picked up my monte last Thursday, I must say, I LOVE IT. I also have a 99 Vette. The monte is pretty damn close to the vette in terms of power, I am VERY impressed! You hardly have to touch the gas and you can chirp the tires. If you were to floor it, you would give quite the smokeshow! I cant commend on the GXP etc, but the pickup is phenominal!
And for a stock exhaust, it sounds pretty badass, you KNOW it has a V8 under the hood!
Here are a few pics....

The GP is a more performance oriented car. I believe it has wider front wheels, where the Chevy's do not. I also thing the suspensions are different, which will make a significant contrilbution to wheel spin and torque steer.

After reading the C & D road test on the 06 Impala SS I thought they were in error when they said the Impy had 3.29 gears. I checked out the Chevrolet websites (U.S. & Canada) and sure enough they seem to be right. BUT! I took a look at this website http://eogld.ecomm.gm.com/NASApp/dom...page=6&butID=3 with give specs on the 06's and 07's and they say the same ratio as the GXP! Who's right? Can anyone shed some light on this?

that's correct, the chevy's are 3.29 & GXP is 2.93, final drive ratio....why I have no idea, but my GXP ran better than any SS LS4 to date, stock for stock, need to hold 2nd through the traps in the GXP and it picked up .2 and 2+mph the chevy's shift into third early on whereas the GXP will pull 101+ in 2nd, I used to shift into 3rd right before the finish, trapped 102+ numerous times.
