What are rears? What are good rears? Im young and trying to get some basic knowledge about the wonderful world of cars, and my iroc

I remember when I was your age.....3 years ago.
A rear or rear end is the axle that holds the actual axles and differential or pumpkin.

Good rear ends are Ford 9", GM 8.5" 10 bolt, GM 12 bolt, 14 bolt, Dana 44, Dana 60, Dana 70 (extremely strong but parts are extremely hard to find), and if youre a engine builder madman, 2.5 ton axles (save them for off road).
Best bet is stick with 12 bolt- 1st gen camaros came with them and parts are easy to find.

make sure you get a posi, too. one-wheel peels are smokey, but no fun. best type i think is a Eaton posi. hope i helped you out.

Yes!! Thank you very very much!!!

Also, do you know what would come stock on my car? 86 camaro iroc 305 4bbl standard tranny. Do you know prices on good posy's?
