friction modifier, yes or no?

[dashapht]

Friction modifier keeps the clutches in the differential from prematurely wearing out. You do want then to slip; that's the whole point of a differential. It differentiates the speed of the inside and outside wheel in a corner. If it didn't do that, you'd break parts. Then when it's under load, it locks pretty much solid for maximum traction.

Here is a good article on how limited slip differntials work: http://www.auburngear.com/oemdiffere...tedslip/about/

Bottom line is that you need to use the modifier or you'll be replacing your diff. shortly.
