well after getting stuck with only one wheel spinning with my zexel torsen ive decided that i need to get the rear end locked up. getting a locker isnt an option because of the pricetag, so i think a spool is my only real alternative. im not too educated on them, so if someone could help me it would be appreciated. what is the difference between a mini spool and a spool? do i use my stock differential with one? anyone actually have one that they drive on the road? how bad do the tires chirp when turning? once again, thanks guys!
