Description:

FS is my OS Giken 1.5-way rear differential. Selling because I installed an ATS differential.

After initially installing the OS Giken (custom, extra charge), I had TRE re-set it up to be a little more aggressive, which is the current setup on this differential. I set personal bests at every track I've been to (not necessarily because of the diff), which had been previously set on the car with the Cusco. Fluids flushed and maintained frequently, with proper break-in procedure.

The diff was 1,400 for a custom build, and a few additional hundred to have TRE set it up. FWIW, this diff has been 100% silent in my car, but your mileage may vary. Will fit all non-AYC Evo 8s and 9s, and I believe it will fit the AYC Evo 10s as well.

Looking for $1,000 shipped + paypal'd.
