Drilled front brake disc for early Griffith and Chimaera 400 which is 240 mm OD. This is the early vented disc and is drilled to allow for improved cooling/outgassing under braking. After 1997 the 500 brakes were adopted throughout the range. See part no. TVR J0146 for 500 front disc. This drilled front brake disc is an ideal complement for our TVR J0106 RG, which is the rear disc drilled to match.
