The title says it all, is there anyone around here who has experience with the BOSCH Motorsport M4 ABS system? It seems to be the best in the market and I`d like to use it on a top spec GTR build: www.bosch-motorsport.com/content/language2/html/37...

The main issue will be to fit the wheel speed sensors - any suggestion what kind of toothed wheel could be used on the wheels? For the rear wheels it would be easiest to use the factory supplied wheel on both sides of the driveshaft, but I haven`t found a solution for the front wheels yet. They need to have the same amount of teeth (which should be around 48 for best results).

The issue was discussed before but no further info about any result. Any input is greatly appreciated.

I`m expecting the ABS system to arrive this week after they built a custom loom for the Ultima (which I had to measure). I`ll post some pics later.

Here`s the layout plan for the ABS M4 wiring loom. You need to decide where the control unit sits (the only place I could think of was beside the battery). Then you need to measure each cable length and send them the numbers (e.g. A1: 50mm).
I hope my measuring istrument was calibrated correctly (tape measure) - if so I could post the numbers as it`s not so much fun to measure in a finished GTR.

I will place my control unit directly in front of brake master cylinders. I have that drawing and yes measurements are difficult. Thats why I am interested in your dimensions. Quite understand that you may tell me to take my own.
What do you mean directly in front of the brake master cylinders? Afaik there`s not enough space - it is much better mounted and protected underneath the operning for the steering rod. There`s a rubber mounting plate supplied in the kit that you can bolt right into the panel.
Here`s the final layout for the ABS loom in the GTR. I had them move the brake pedal switch cables to another position that made more sense in our case. The wheel speed cables are quite short in the loom as the sensors have a 900mm cable already.
