If someone knew more about electronics and we could use an alternative sensor that packaged well would be another option.

For reference, here is their X-Tracker hub they developed with SKF

C6 Corvette SKF HD (X-tracker) Racing Hubs w/Active (Bosch) ABS Sensor

An alternative sensor wouldn't help, it has to mount in the same place.

The rear tone rings are on the axles, so no issues there.

All you need is a tone ring that fits in the original front location, and has the same teeth per revolution. Thats not super hard to find.

Then just space the sensor out the correct distance.

I would be happy to test all of the above in exchange for a beta set of hubs :)

Since they are going with a clean design, we can try to source a more cost effective (higher volume) stud and offer those as well. Trying to maintain the OEM 12mm x 1.5 thread so you don't have something different front to back though

I would have to see the output of the sensor to compare to the Miata output. But with the correct number of teeth and the correct output signal its possible.

My thought was to replace the tone ring and pick, moving to something integrated that could potentially package better. The small diameter of the tone ring is the issue, and without moving the pickup I don't see anything easing that

Exactly, that's what I'm after

As long as you match the teeth per revolution and the vr signal output you should be fine.

Send me a prototype and I'll test it :)

No. Mazda changed/upgraded the front ones (IIRC sometime in '04). Thus the late NB have different front rings and sensors.

I believe the sensors are still interchangeable. I just setup an NA ABS hub with an MSM front sensor.

The newer sensor part number doesn't supersede the old one, so I would keep each sensor type to their corresponding trigger ring type (especially for such critical thing as the ABS system).
Not all MSM use the new type front sensors/rings. The change happened somewhere in the middle in their life cycle and is not MSM specific but affects all NB cars.

Interesting. I have 8 sensors at home, and a few look different. I will take pictures and compare when I get my spindles back from powdercoating.

How are you going to space out the front sensor when it mounts through the upright? You'd need to drill a new hole.

Very true, I was thinking about the rear.

The integrated sensors look boss

Not to hijack, but I'm FEA testing front and rear hubs now. Samples will then be tested by Keith Tanner and others. Soon. Price = competitive with Mazda, and will include 70mm studs pre-installed.

The big difference? Tapered bearings.

yuusssss

No abs would be a non-starter for me as well. I won't give up ABS.

Holy crap that's great news!!!

I've gone through 3 front hubs in 2 years of tracking the Red car. 2 were bearings. But 1 was cracking of the hub itself, which was pretty nasty although I didn't lose a wheel and was able to limp it in.

I've lost 2 rear hubs, both cracked although I caught those cracks with inspections.

So, tapered bearings is only a partial solution for me if we're building "lifetime" hubs. And, yes, $3-400 for a lifetime hub seems like money well-spent.
