I started the race with the 1.2 mm steel chassis to get a first impression. The car was quite fast, but something was missing and it was quite difficult to drive. I was also running short lower arms and short links until the last run, where I wasn’t satisfied with my lap times.

I then switched to the 1.5 mm aluminum chassis, which I used during the entire indoor season. I felt more comfortable, the car was easier to drive, and I also gained corner speed.

After that, I decided to install the soft CFF-S upper arms. This gave me more lateral grip, better traction, and improved corner entry.

I also adjusted the droop with more rear droop (22.4 -> 22. and slightly less front droop (23.8 -> 23.6). This resulted in a more stable car, with better corner support and more precise steering, while reducing overly aggressive reactions.

To regain even more drivability, I glued the rear tires to 58 mm, in addition to the front tires already glued at 60 mm. I was then able to recover my corner speed while maintaining grip and the maximum steering I was looking for.
