Wilwood Front Hubs - Front Wheel Speed Sensor

[GoodysGotaCuda]

I would like to not bother with the "perfect run" traction control I have on my 'Cuda currently and would like to go to a %slip system.
I am looking to see if anyone here is running Wilwood front hubs/brakes had setup a front VR or hall sensor. If so, how did you mount your sensor?


Currently I am thinking of installing longer bolts in the empty lug holes with a jamb nut to get the pickup closer to the knuckle. It should make the sensor less sensitive to vibration that way. Do you have something different?

Sorry for the flipped image

Was hard to get the full mounting but should give you an idea. This works for my Stack dash speed sensor. Mounted the sensor to my brake bracket.

Nice, is that a VR sensor or Hall Effect?

I picked up a hall effect and would like to pickup off of the internal rotor vanes. That should provide some very high resolution results.

Its a proximity sensor (I think the same as VR)

Seems very accurate with the 5 inputs (hub sensing bolts)

VR is a two-wire and generate an AC current. Hall Effect has 3 wires and it's own reference voltage.

btw is that a crack in your pictured bracket? Just below the allen head

I can’t tell how many wires as it’s a sealed wire. I looked it up online for a Stack race dash and it said it used a proximity sensor.

Not sure about the crack. Good catch, it looks like it..I’ll pull apart this weekend and check. Last autocross we did a couple weeks ago was crazy fast and had two high speed brake points. (100 to 20mph) first time I ever had brake fade.

I found this. Looks like my proximity is a two wire

I picked up a short Hall effect sensor and plan on using the rotor cooling vanes as my trigger wheel. I should have something functional here in the next couple of weeks.

I'll get to testing the signal this week.

I checked my brake bracket, all good. Weird, not sure what that was in the image but it sure looked like a crack. Gave me an excuse to check everything and clean/repack my bearings.

Hopefully you will have enough sensing area on the brake vanes for the Hall effect to pick up. Mine was sensitive to area/distance.

It would be nice to run that rotor on a lathe and true up and even out the cooling vanes. They are just cast, so I assume there is some variance in how close they come to the sensor.

It's an option. The two setups that I have seen do this successfully were "as cast".

I build these for my hubs. Not Wilwood, but might give you an idea:

Thanks, what are you using the data for? Launch and TC?

Laser cutting a tone ring will likely be my next step if this doesn’t work.

sweet success..love it when stuff works when its suppose to..good job!!

Thanks! I have a very clear front speed sensor signal and the initial steps for a launch/traction control are in place. My ECU is correcting for wheelspin and keeping the car moving forward and straight during low gear hits.
