I'm more interested in this "modern ABS" being planned. I know the 968 font hub's & spindles have the reluctor ring & stuff on them, but theres got to be a better solution, right?

I made sure to buy late offset turbo components that had the ABS sensors and tone rings . I have a complete harness from a B5 chassis VW / Audi platform . Compact unit with integrated ECU . It is can enabled so it can be used with a standalone ECU for part of traction control input . Still working out all the little details at this time .

SPEC is not doing it yet. I think they want to see some volume before they commit to a new design and an additional part number. I think the pilot bearing adapters will be pretty inexpensive, though. I’m getting them quoted in a batch of 20 now.

Is this potentially another 07k swap? I *think* it is a 07k at the end but not 100% positive. Can anyone confirm? Do you folks know these guys?

That looks like a lot of serious work Alan. Way to go!!!! Looks great! Can't wait to see and hear how the welding and final check of the bellhousing goes.

If it is a non-ESP car, the traction control system is the EDL software, which mimics a locking diff using wheel speed signals and applying brakes to one side. The EDL system won't limit total wheelspin, only relative wheelspin L/R.
An ESP car has EDL but also has an ESP system which will brake one wheel as seen fit to attempt to neutralize the car's behavior if a certain threshold is met of the yaw sensor, accelerometer, steering angle sensor, requested throttle, wheel speed, etc. The ESP system will also limit total wheelspin.
The traction control system itself is primarily designed for slippery conditions and does not function above 50mph/30kmh.
For the FWD cars there is another system called ASR, which to my knowledge is just EDL. It's function is limited to a lower vehicle speed I think.
It's worth noting that the software coding is written for a car that has a roughly 60/40 F/R weight bias and either FWD or AWD, depending on the application. It probably won't work well in a car with different dynamics.
It's important to note that traction control and stability control are NOT the same thing. Traction control is very often mistakenly used to refer to stability control, even at the manufacturer level.

There are a variety of systems encompassed by the VAG ABS units. The B5 era featured changeover from EDL-only to EDL and ESP. (Electronic Diff Lock, Electronic Stability Control). The harness is different between non-ESP and ESP cars. The ABS units and pump system are also different.

An ESP car has EDL but also has an ESP system which will brake one wheel as seen fit to attempt to neutralize the car's behavior if a certain threshold is met of the yaw sensor, accelerometer, steering angle sensor. The ESP system will also limit wheelspin in a low-grip situation.

Thanks! We’re currently machining the mounting plate for the clutch release bearing. I should hopefully have it done tomorrow. I also have the clutch hydraulic line and fittings on order to connect to the factory master cylinder. I want to test with that first to see if it has enough displacement for the Solstice slave.
