Re: which gear
well 342's will accel quicker and have worse gas milage, while the 273's will have a higher top speed and better gas miliage. it is all a comprimise.

Re: which gear
If the 89 had PBR's, I'd say that was a plus (but it probably has drums).

Re: which gear
Im not sure what PBR's stands for... Im assuming its something with disc because you mentioned drums. Which yes it has drums. Wish all four corners had disc though.

Re: which gear
PBR's are the 1LE rear braking system: 11.7 rotors with alum calipers (89-92). These can be swapped on a 9- or 10-bolt without much difficulty, especially if you already have the rear disc rear end. Even if you don't, they can be added to a drum rear. Search ebmiller88 for the details if you're interested in the latter. Check the following link if the former:

Re: which gear
thats funny..... lmfao
he asked about gears not brakes....
it all; depends on what you plan on doing with the car.
most will say 3:42's b/c its more of an all around gear. 2:73's dont do much of anything good except for going down the highway.
