If you can check the name of that adapter it would be much appreciated. I don't get anywhere near those update rates. Rpm as an example lags badly behind. Another option for me would be to run HLT on Android on the head unit using a mini-PC instead. I am a bit undecided about that.
SPL arms are really nice. I would like those too, but they would be too obvious at TÜV inspections. I have the positive traction inserts too but I didn't install them yet (a bit afraid to mess up the threads as quite a few has done).
I run 1 mm toe out in the front and 1 mm toe in rear. In the beginning, I ran 7 clicks on the street but I got too lazy changing it around. So the last part of the season I just ran the setting I use on track 5 in the front, 4 rear. A girlfriend got car sick from driving with me, according to her it was much better at 12 clicks.
Now I have Michelin Primacy on the car (my grippy winter tires

) and I set it as well at 12 clicks I think. I don't drive it much right now, though.
