Traction control, wheel speed sensors... who wants 'em?
So I'm having a buddy of mine who works at a steel facility lazer cut a set of trigger wheels for the FC. These will be a 24 tooth count wheel cut from A36 mild steel. 5/16" thick in the front, 1/4" thick in the rear. They will both bolt to the back of the drive flanges.
In the front, you would need a GT101DC sensor, a 5/16" dill bit, and a 3/4" drill bit to mount them on factory ABS equipped knuckles. Or if you're baller like me, you have a 1/4" - 1 and something colbalt step bit. The better the 3/4" bit the better, as you need to drill out the cast iron or whatever it is hard as hell steel front knuckle to at least .7" to accomodate the sensor. In the rear you would need to remove the drive flange, bolt them on, and press them back into the hubs. I didn't pull a measurement on the bearings as tyhis just now occured to me... you MAY be able to slip them on over the bearings, meaning press the entire bearing assembly out, slip the wheels on, press the whole assembly back in. Otherwise when removing just the drive flange, you are almost gaurunteed to destroy the bearings which cost $55 each.... You would also need to figure out a way to mount the sensor. According to my math, using a flat plate of AL, and bolting them to the dust shield bolts, you'll end up with ~.035" of clearance... it doesn't get much better than that. This has the potential to be a one time gig, I expect very little to zero interest in these and thus there won't be any GB pricing structures so don't even ask ![]() We're also looking into getting them cadnium or zinc plated. After a year of use on my car, the fronts are showing age already. So, if you're interested, post up.... Think Race Logic systems, wheel speed sensors, aftermkt speedo's, AIM or Racepack digital dashes, baller MoTeC Traction Control systems that I was looking at tonight and have built in 2-step and launch control... expect more fireballs than usual at this years DGRRXI, that and I think Dave's asshole might pucker a little when we dial this thing in on the street ![]() ![]()
