Performance Axle Ration

I'm getting ready to order a 2008 Convertible with paddle shift and am
considering ordering the "2.73 Performance Rear Axle Ratio". Can anybody
give me a description of what that is, and difference it makes in
acceleration or speed? Is it worth $395?

Thanks, Scott

Sure, this principle is the same in all vehicles, although there are many
other contributing factors that alter the details. Generally, a lower gear
ratio (3.55/1 being a lower gear ratio than 3.00/1) reflects a quicker
launch, quicker run through each gear, and ultimately (theoretically) a
lower top end speed.

And on a car driven on the road, higher gas bills.

2.73 does not seem like a performance ratio. Could it be 3.73? What is the
standard ratio?

In an older car it wouldn't be but the six speed automatic makes up
for it with a much lower first gear and wider range to the top.

In a 2005 the rear gears from the factory a auto: 2.73:1 or 3.15:1;
manual: 3.42:1, limited slip. Would the be the same in a 2008?

nope for 2008 the auto is 2.56 or optional 2.73 and the manual gets 3.42

I have a 2004 Auto with a 2.73 ratio.
The good news: 21 MPG around town, 25 highway.
The bad news: Could be faster, IMHO.
A 2.73 rear end ratio IS NOT a "performance" item. It gives you better MPG
and slower 0-60.....0-100 on up times. Helps Chevy meet their CAFE numbers.
The higher the number, the more "performance" from the rear axle ratio.
2.73.....bad. 3.48...good 4.11....better
Gas mileage?? Who cares. That's not why I have it. It's a 'Vette not a Vega!

One other thing: 2004, Auto 1900 RPMS=105MPH w/ a 2.73 rear end.
