M2C7100 M2C Racing Adjustable Rear Toe Block System for Ten-SCTE, 810, Ten-T. Toe blocks are made with 7075 aluminum for maximum strength and anodized black. The hinge pins are made with 01 hardened tool steel and tapered to allow the hinge pins and arms to rotate together in the delrin bushing.
 This is a dual style system meaning that the arms can rotate around the pin as well as the pin rotating in the bushing. What this does is that if you do bend the hinge pin, it will most likely bend in the smallest section of the pin. This area is not in the bushing or the arm, so it will still allow the arm to work properly and not bind.
 The hinge pins are 4mm in diameter so you will have to drill out the arm with the supplied drill bit. The toe blocks are designed to use the M2C Racing Delrin bushing which has proven to last way longer than the stock injection molded plastic that most manufacturers use.
 The rear toe block is set at stock settings and uses the 1 dot insert (0 degree). Included in the insert packet are four 1 dot inserts (0 degree), four 2 dot inserts (1 degree), four 3 dot inserts (2 degree), four 1/4 degree offset inserts & four 1/2 degree offset inserts. This will give you a total adjustment range of 1 to 5 degrees toe with fine adjustment of 1 degree either direction from the stock settings. This is where 95 % of all systems operate.
 The Antisquat block also uses the same inserts and allows you 1 to 5 degrees of adjustment. The Rear toe block has been machined to allow you to lengthen the wheel base by 1/8 inch to suit different track conditions with the use of 1/16 x 4mm id Delrin spacers. This will allow you to run the stock settings or 1/8 inch longer simply by moving the bushings.
 Caution: this may not be a legal length at ROAR races with the arms moved back.
