If you get the SP, the only option I think thats worth a shyt is the SRM, everything else is aesthetic. And just to add, the SP rims are nice yes, but also create more rotational mass and add weight. I'd like to see a base 7AT against a SP 7AT at the drag strip with the same driver and conditions, i'd bet the base has a faster 0-60 and 1/4 mile time.
