A number of people have asked if the ABS/TCS will still work with 21" front wheel. Iv'e gone down the path of full Woody's Wheel Works 21" wheel and hub replacement that has no provision for the ABS/TCS ring and sensor, but for my own peace of mind (and to provide valuable feedback to Woody) I sat tonight asking myself,,,,, "self - How can we check this out?"......... "How do I rig the sensor ring and pick up onto the rim?"......... "What would MacGyver do?"......... Short on paper clips, loosely assembled bullets, and a magnifying glass, I measured the hub to disc clearance and devised the next best plan of attack using some 5.4mm plywood. You may recall from one of the previous pics, the discs on the wheel (Woody's 21"er, not the OEM 19") are spaced off the hub by these beautiful little gold anodized billet components: It happens that the gap between the inner face of the disc carrier and the outer edge of the hub is 5.4mm. All I needed to do then was cut a flange with 6 holes at the same PCD as the disc mounts and sandwich it between the disc and hub. In true MacGyver fashion I chewed the piece of ply to shape (it looks like it at least) and screwed the sensor ring on central. I left the screw points sticking through the back face of the ply... Because MacGyver would: Mounting disc completed, it was time to whip the wheel of and try my new MacGyverABSsensorholderthingy on for fit: Fits first go with no hole filing. Damn Mac's good. Back on with the wheel and I will fab a little bracket to hold the proximity type doohicky off the two bolts for the caliper. That's a job for tomorrow now so I will post up some more pics once thats completed: All in all, an interesting project and it will be interesting to see if the system has enough smarts to compensate for such dramatically different (from design intent) wheel sizes. Later. Greg.
