Big Boy Clutch Stop v.2

The UUC Motorwerks Big Boy Clutch Stop v.2 is a clutch pedal upgrade that allows the driver to precisely set the clutch engagement point. This adjustment can significantly alter the clutch pedal feel for the better. The unit is constructed from CNC machined 6061-T6 aluminum, ensuring durability. Installation of this clutch stop may require modification. One user reported needing to cut the metal threaded shaft to achieve the desired low enough fitment on their 1999 M3. This was in conjunction with a Mason Engineering metal clutch pedal and a different type of return spring. The product is listed for various BMW E36 and E46 models, including M3, 318, 323, 325, and 330 variants, as well as the Z3 M Coupe. However, the installation note about cutting the shaft suggests potential fitment variability and the need for careful measurement and possible adaptation depending on the specific vehicle and existing pedal assembly.
