If you want to drive on hard ground, yes.
i dont know what sizes they are,but the ratios in front and rear diffs will be exactly the same as each other.
Yes, but watch the ratios. Check the build sheet on both cars. GT denotes the rear end gear ratios. GT3 is 3:73. Probably what they have. If both cars have like transmissions, they should be the same.
They provide different gear ratios so that the rider can keep using the same effort both downhill, on the flat and uphill.
Depends on the engine at what it's cruised at, revolutions per mile of the tires, transmission gear ratios, and rear end gear ratios.
Automatic transmission AW71 (740 Turbo) Reduction ratios: 1st gear 2.45:1 2nd gear 1.45:1 3rd gear 1:1 4th gear 0.69:1 Reverse 2.21:1 Rear Axle : Reduction ratios: 3.73:1 Automatic transmission ZF 4HP-22 (with lock-up)(740 GL, GLE)Reduction ratios: 1st gear 2.73:1 2nd gear 1.56:1 3rd gear 1:1 4th gear 0.73:1 Reverse 2.09:1 Rear Axle : Reduction ratios: 3.91:1
The one you have chosen. If you have several sprockets on the rear the biggest is the "first", then you can count up from that. If you have several sprockets on the front as well, then you start counting from small front/big rear (first gear) to small front/small rear, then you start over att big front/big rear to big front/small rear(last or highest gear).
I believe the 3.42 gear was the lowest gear you could get that year, what was standard I don't know.
YES, THEY NEED TO MATCH.
That depends on the drivetrain, motor, rear end gear ratios, and whether or not the owner has it governed.
most common ratio is 373
It depends on whether you are talking about the front sprocket (the one at the pedals, called a chainring) or the sprocket at the rear derailleur. The lowest gear at the front is the smallest sprocket/chainring. The lowest gear at the rear is the largest sprocket. So if you combine the smallest sprocket at the front with the largest sprocket in the rear you have the lowest gear available on your bike.
The fourth generation General Motors F-Body (Camaro/Firebird) was offered in multiple rear end gear ratios. These included 3.02, 3.42, and 3.73.
