Overall Assessment

The product has received high acclaim for its superior quality and practical functionality, further acknowledged as ideal for racing conditions. Consumers commend its easy installation, perfect fit, and adjustment ease. A distinguishing feature mentioned is the master cylinder cover's 'bailing wire' retainer, designed for easy hand removal, a plus for reservoir access. The appealingly rugged pedal assembly stood out for its quality and stoutness. The retaining clip design for afco master cylinders has been praised as more user-friendly compared to competitor products. Encouragingly, customers confirm they've found no better price elsewhere for an equivalent kit.

Very nice break pedal kit. I like the afco master cylinders slightly better than the Wilwood master cylinders because the retaining clip that holds down the cap has more room for your thumb which makes it easier to push off without using a screw driver. Could not find a better price on a kit like this any where else.
