Craig, if anybody here is flat spotting 4 sets of $1500 tires, they definitely should stay away from wheeled office chairs. My original thinking was hard street driven all weather, high dollar cars, to reduce cost of shunts and hospital bills. However your example works.
So tell us, how complex/involved is it properly dialing in a custom aftermarket ABS system?
Are there different selectable settings for track/street/etc use?
The Bosch M4 Motorsports unit is identical to its OE counterpart, they differ only by programming. The M4 has 9 preprogrammed maps adjustable from a rotary switch (full wet to grippy dry). It also has 2 programmable maps. Just 2, so the 9 that the Bosch engineers preprogrammed are pretty damn good.
When you set it up, you enter your car data, weight, tire size, CG, etc, etc. The included 3-axis G-sensor and wheel speed sensors are the input data to the unit.
This is a Motorsports piece, so you have to have the Bosch Box II adaptor to connect to a laptop! That's another 1K.
I'm running a Motec system on the 'Cuda, so I use the wheel speed data from Bosch unit to feed the Motec for Traction Control.
I run a floater rear and big bearing hubs, so I machined the rears to accept a custom tone ring and made an adaptor that doubles as a seal retainer for the front:
