And the Stock Spec is rated at 100A continuous, while the full 3.1 is rated to 120A. I have both, & honestly, unless you're planning to bolt in as much motor as possible, you really just don't need the full 3.1, the Stock Spec can do everything most of us need, shaves 10g off the car's total weight, & costs about $56 less. For me, I have 2 Stock Specs & one full 3.1, but the only reason I bought the full 3.1 was because when I needed one, EVERYONE was out of stock on the Stock Spec. If you'd like to save a little money, then I'd STRONGLY recommend the Stock Spec, I think it's the best value for the dollar you can get....
