Someone order it for science. Or a diff expert explain why this is a great/awful idea.
I might contact them and see what kind of discount I can get, and give this a shot.

For $300 it might be worth the trial, if it toasts the diff I've seen new ones at my local yard for less than $200.

Good info, 2 years is totally on point with most diff servicing

Honestly, a real LSD is 'only' $1k - $1.5k more... as with most things on our cars, if you're going to the trouble of removing the thing and rebuilding it, isn't it worth spending a bit extra and doing it right the first time?

On the flip side, welding your diff costs nothing and while it's a bitch to drive on the road, (I must say driving an aggressive race/clutch diff on the road isn't always fun) it would probably be more reliable, more predictable, and cheaper.
Saving $1k alone is worth it to me, extremely reasonable price. ESPECIALLY if it works well.
