I think 11.0 et or quicker is when you are required to run c clip eliminators. It isn’t really enforced though until quicker than 10.0 when you would need a chassis certification. C clip eliminator is more of a want than need for 11.0 or slower.

Building a rear end gets to be pretty expensive. So it’s nice to start with the strongest thing you can find. 8.2 grey iron case your starting near the bottom for strength. But if your not using drag slicks, it is a doable place to start on a street build. Best not to get to much money wrapped up in an 8.2. Especially if your hiring the work done on it. Hiring it done, buy a complete 9” from quick performance and be done with it.
