Our baseline setup originated from ETS Rd. 4 in Daun and served as the starting point for our team drivers. The setup performed exceptionally well, delivering strong pace right from the first practice session.

Because tire additives were unrestricted and the Rush 30 tires generated more traction than the Matrix tires used at ETS, we needed to make several setup adjustments to maintain our competitive pace. The most critical adjustment was applying glue higher up on the front tire sidewalls. While we typically run 59–60mm of glue at ETS, the increased traction required us to raise the glue line significantly to 62–63mm. This improved drivability and prevented the car from traction rolling (flipping).

Lowering the roll center further improved handling by reducing chassis roll. This allowed the car to carry more corner speed and made the steering feel much more precise.

Another crucial factor in high-grip conditions is the use of upstops, a new feature on the A11. Their function is straightforward: by running less upstop travel (a smaller value on the gauge), the chassis stops rolling earlier, which significantly reduces the risk of traction rolling. This tuning option can also be applied to the rear—for instance, to prevent the car from squatting too heavily into the rear suspension when accelerating out of corners.

In addition, we refined the shock package to better control weight transfer under high load. Slightly stiffer damping helped stabilize the platform in fast direction changes and maintained consistency over longer runs. Overall, the goal was not to reduce steering, but to make the car calmer and more predictable at the limit while preserving corner speed.
