Review on Spectre Performance 6092 12 Bolt Differential by Jim Cox

Appears to be a good quality case. It fits snugly, appears to be made of quality materials and the screws were NOT too long or poor quality as some people have said. I made sure the bolts weren't all the way down before tightening them and then tightened them to the correct torque with no issues. I suspect that people who have complained about the length or quality of the screws may just have overtightened them. Time will tell but I hope it will last longer than the factory finish. I've never had rust on the diff cover. but they shave weight wherever they can to meet fuel economy standards, so I expect to see more stuff like this in the years to come.
