Question for those who installed aftermarket LSD
 

Just picked up a Tomei 2-way LSD for my FR-S and I had several questions.

Did you guys reuse the side bearings? It's my understanding that if i reuse the side bearings, I can use the original thickness washers on each side but if I install new side bearings, I may need to select different sized washers.

Did you guys get new set bolt locks for the ring gear bolts? I figure its just extra assurance that the ring gear bolts will not loosen.

Regardless I'll still be checking runout, backlash, tooth pattern, etc. but just trying to minimize downtime.
