H&R Trak+ 20mm DR Wheel Adaptor Bolt 4/108 Center Bore 57.1 Bolt Thread 14x1.5 - 40234571

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.

Select applications now also available in black hard anodized.

Notes:

All DR-Systems require longer wheel bolts. These must be ordered separately. H&R Wheel Spacer Bolts are listed here. 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 01
Round head for M12/d24 mm, for M14/d28 mm End digit 02
Round head for M12/d26 mm (e.g. OE VAG-wheels) End digit 03
Flat 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 length
M12 x 1.50 = 6.5 turns = approx. 10 mm of load bearing shaft length
M12 x 1.75 = 6.5 turns = approx. 12 mm of load bearing shaft length
M14 x 1.25 = 9.0 turns = approx. 12mm of load bearing shaft length
M14 x 1.50 = 7.5 turns = approx. 12 mm of load bearing shaft length
1/2" 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).
