Up for sale is a built diff. It is a 3.85 6MT diff with a Wavetrac installed. Nothing wrong with it. Diff includes the equal length axel stubs that you need to run with the wavetrac (which are hard to find these days).

Edit: I just want to add that I drilled out the "ears" of the diff for 14mm bolts because the stock 12mm bolts break. The bolt through is easier too since there is no chance of stripped threads when installing the diff.

Shoot me an offer!

Equates to a 6.5% difference in torque. Avg person probably won't even feel that and won't be able take advantage of it. If you are looking to really squeeze a tenth or two out of the car on the track like that then skip the Wavetrac and get a custom clutch-type that the GT4 runs for 2-3x the price imo

I got the 4.10 put in my car and there wasn't that big of a difference. Not worth the $$$.

How does the wavetrac behave on the street?

You don't even know it's there. Very smooth operation. Maybe a clunk noise here and there when parking but I also have solid bushings.
