The carefully matched parts in the Maximum Grip Box will turn your Mustang into a world-class performance car-you won't believe how it performs. Our customers say it's like magic!
Each Maximum Grip Box is customized to suit your needs; it's not a one-size-fits-all package. We help you choose the right parts to make your Mustang ideal for your exact situation and driving style. Whether for the street or track, a Maximum Grip Box is the obvious choice when you've got to have the best for your Mustang. This is the package used by winners in the NASA American Iron series.
