I am contemplating the acquisition of a limited-slip differential and need your advice: Should I purchase a pre-owned unit or go for a new one?
A pre-owned item is likely to be somewhat worn and maybe less expensive. Require a reconstruction?
A new unit will be acquired, requiring startup costs but no reconstruction. I am capable of doing all the necessary labor to install the physical device, plus I know an individual who can provide shimming services for a fee.
I own a 323i Touring, equipped with a late ZF transmission (presumably) and a medium case (again, presumably), with a 2.93 gear ratio to the best of my knowledge.
I am also contemplating a little increase in ratio. Thus, whether new or pre-owned. I presently have around $1,000 in my budget.
Thank you, everyone.
