Rêve D ultra lightweight M4 nut

Rêve D have introduced their large-diameter ultra-lightweight M4 serrated nut, optimised for the rear of the car. Their original RD-013 nuts have been well received as being ideal for the front, these are their new rear specific competition M4 nuts. Increasing the diameter of the flanged part helps to control some of the lateral forces applied to the wheel mounting point, helping to improve side bite. The hexagonal dimensions are still 5.5mm which is the same as RD-013 in order to use the same box wrench for both front and rear.
