H&R TRAK+ Wheel Spacers move your wheels and tires outwards so they are more flush with the fender- instantly giving your vehicle the perfect stance. High end sports car manufacturers use every millimeter of fender space available in their design for the best looks and highest performance and so should you. With TRAK+ you can fill the gap in your fenders and GO WIDE!TRAK+ Wheel Spacers are manufactured from a special proprietary alloy specifically developed for H&R that is lighter and has a higher tensile strength than 6061-T6 billet aluminum. H&R TRAK+ Wheel Spacers are hubcentric and feature a full contact hub- just like the factory hub- for even load force distribution and lateral support. Additional Note 1 If the depth of the wheel spacer is smaller than the length of the standard studs, the wheels used must allow for small cavities in the mounting pad of the wheel. If using wheels without cavities, the standard studs should be shortened so that they do not extend beyond the height of the spacer. Additional Note 2 These are hub-centric flat disc type spacers which require the factory hub to center the wheels. Please measure the vehicle hub to verify sufficient height will remain to center the wheel after spacer installation.
