I feel like they have been pretty open with their build list, which you can infer performance numbers from, with special consideration for environment variables. In my opinion the target buyer is something that may know enough about these builds to know they want more, but also may not want to get it done on their own and like the idea of a warrantied package. Other than the pivot on the wheel/tire setup (which I think makes sense), I feel like your average informed buyer should know exactly what they are buying and how it will impact the vehicles performance.
