BMW Concept M4 GTS – the pinnacle of street-legal racers

That spoiler will make very little difference for improving issues with traction. Aero downforce only kicks in at a speed that's too late for controlling the rear end with regards to traction. It should help stabilise the car in high speed corners though. What will help with traction in lower speed corners is a huge rear diffuser like the DTM/F1 cars have. A blown diffuser would be even better.

Ok, ok.. Reduces some lift though that still helps get the grip down. Amiright?

Stock from the dealership? or was it an aftermarket addon?

Yes, stock from dealership. Sprays directly onto top mounted I/C.

Which is ENTIRELY different from the "water injection" that BMW are implementing.

I would also guess that Subaru are not the only ones to have water injection onto the I/C as a stock specification.
