Please verify bolt specifics before ordering (taper or round bolt head and shaft length). Product Description Wider is Better! 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 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. Additional Note All DR-Systems require longer wheel bolts. These must be ordered separately. When ordering wheel bolts, please follow these guidelines: a) If possible, name the brand of wheel. b) New bolts must be longer than the original bolts by the width of the wheel spacer used. c) The bolt head must be identical to the existing bolt:Taper 60° End digit 01Round head for M12/d24 mm, for M14/d28 mm End digit 02Round head for M12/d26 mm (e.g. OE VAG-wheels) End digit 03Flat head for Porsche original wheels M14 x 1.5 End digit 06 d) Safety guidelines (Minimum number of turns for wheel bolts / nuts):M12 x 1.25 = 8.0 turns = approx. 10 mm of load bearing shaft lengthM12 x 1.50 = 6.5 turns = approx. 10 mm of load bearing shaft lengthM12 x 1.75 = 6.5 turns = approx. 12 mm of load bearing shaft lengthM14 x 1.25 = 9.0 turns = approx. 12mm of load bearing shaft lengthM14 x 1.50 = 7.5 turns = approx. 12 mm of load bearing shaft length1/2" UNF = 8.0 turns = approx. 11 mm of load bearing shaft length e) Please ensure that the wheel bolts do not damage any part of the brake system (ABS sensors, etc.). Turn the wheel by hand and check clearance on the inside of the hub. The wheel should rotate freely. (Maximum tolerance for some vehicles is only 2mm -- i.e. Rear Axle Mercedes).
