Speedyk 0 Posted November 30 I am planning on running an Allison Legacy in ST4. I was curious if I am allowed to modify the floorpan (lower the floorpan) underneath the drivers seat? I am assuming that I can not because of the statement in 6.5.3 in the ST4 rules that states: "The following vehicles are approved to use "Production" vehicle status, provided that the frame/chassis, body/aero remain in the original manufactured configuration, as specified by the manufacturer" I was just trying to get some clarification for this, and I'm not sure who I need to specifically ask about this. The intent is to gain a bit of clearance around the helmet area. Any help is greatly appreciated. Thanks. Share this post Link to post Share on other sites
davidfarmer 0 Posted November 30 considering production cars cant do it without a penalty, I can't imagine you could it without penalty. May be an email question since it's very vehicle specific. Share this post Link to post Share on other sites
