but maybe not for a sp bolt-on
Not sure about runner length, but apparently it works great so far... can't be any worse than stock!! It's nice to be able to just take a part off, and put another one on without worrying about anything else - especially when it comes to turbo's and the person isn't aiming to re-fab half the car. Perfect for the jackass like me who doesn't know how/have the motivation or money to do something like that.
