The past week, I started testing the SP1 on asphalt for 4 days in preparation for the ETS season. Spent a lot of time testing chassis, tires, body parts, and some setup modifications.

I built a base setup, which I tested on both the 1.5mm aluminum chassis and the standard 2.2mm carbon chassis, and amazingly both cars were equally fast. Some setup changes I made:

  • Front springs 2.2 -> 2.0-2.3: Especially for tracks with unevenness are advantageous
  • 0.5mm anti-dive: For more bite into the curve. Helpful on technical routes like Andernach
  • Front stabilizer 1.2 -> 1.1: For more traction on the front axle under load
  • 0mm rocker shims: For better rolling behavior in the curve. (Important: you need to extend the rocker arm by about 1mm when removing these shims)
  • 0.5mm shims less tumble adjustment on new tires
  • Tires at 65 degrees for about 15-20 heat: Optimal window for the current matrix tire so that it deflates as slowly as possible during the first battery.
  • 4 degree relapse: For more bite into the curve
  • 0.5mm -> 1mm Ackerman shims: For a straighter driving behavior, especially on tracks with low grip
  • Swapping back and forth between different top decks. (Fiberglass, carbon, various cutouts... )
I was on the road in Andernach and Rosenheim, two tracks that are very different from the basics and on both tracks I spent mainly time to understand the new Matrix tires. The tire comes out of the bag with a lot of grip and is therefore very very soft. But this also means that he drives off pretty fast, which can be detected in the first run over 5 minutes with this tire. So I’ve been trying to make the tires less straining with some setup changes, which worked well.

Also, I have tested a lot between the Zooracing Wolverine and Jackal. For me, both squares are very very good, and I think that the jackal can convince especially with low grip. Compared to the Wolverine, she has more grip and a more even balance, which was particularly noticeable in Andernach.

I was able to detect few differences between the aluminum and carbon chassis. I was surprised that both chassis worked so well, which is why I haven't decided on a chassis yet. More tests to follow.
