Getrag differential from a 2007 CTS-V. I was wondering if there is a differential shop that is able to tweak the unit to provide better strength and longevity. The case has been known to crack/explode under heavy drag style launches, and it quickly overheats under open track abuse. I thought perhaps a shop may be able to debur the interior, shot peen the case, micropolish the ring and pinion, whatever is the current techniques at maximizing a differential's performance.

Anyone have a shop recommendation?
