thoughts on mini spools vs posi or lockers?
Since I have no clue to rearend units I would like to know what your thoughts are on mini spools. Here is a bit more of info. I have lq4 mild cam, ls2 ported intake and a 4l60e. I was thinking of running a 3.90 gears, and possibly a mini spools. I was considering a detroit true track, or a posi unit. let me know if their is any down fall.
Thank you.---------Fabian Sanchez-----------

A spool should never be used on the street. They are dangerous. They cause bad handling and they also cause parts to break due to the stress that is caused from turning corners. The Eaton Posi is a very good differential for most GM cars. If you want to go drag racing then a locker might work a little better for you. If you want to go road racing or auto cross then a Truetrac ot Torsen might be best.

What bgh said.
I'll repeat the most important part: A spool on the street is dangerous.

That is the route that I took for my 12 bolt. Purchased everything that I needed from BGH. Originally Posted by big gear head
