My Tech Report & Set-Up Details from Masters of Foam 2024

The Masters of Foam was my first race with the new X12'25, and the car performed exceptionally well from the first practice session, even when traction was low, all the way to the end when traction increased significantly. I made a few setup changes during the event that I would like to share, as I hope you find them helpful if you’re also using the new X12'25.

I started the event with a nearly basic kit setup. After a few runs at Hudy Arena prior to the event, I felt confident in the car’s performance leading up to the Masters of Foam. However, the first practice was quite hectic, as the car was aggressive to drive. As a result, I made several adjustments for the second round.

I increased the front kingpin oil from 10k to 20k. Since front additive timing and sourcing distance are particularly sensitive in the 1/12 class, I also reduced the additive timing and area in front, adjusting the settings from 12mm and 10 minutes to 5mm and 5 minutes. Because the car was so aggressive, I decided to change the wheelbase from short to long.

These changes made the car significantly easier to drive in the second practice. However, it was still too loose on power; while the car entered corners well, it lacked stability. I reverted to the short wheelbase and improved on-power traction by moving the pivot mounting position from the center to the long alternative. Feeling I could handle a bit more steering, I increased the additive timing and area by 1 minute and 1mm, adjusting it to 6 minutes and 6mm. These adjustments benefited the car, resulting in excellent drivability and speed from the start.

The only issue I faced in the last practice was a lack of rear traction toward the end of the run. To address this, I changed the rear additive timing from 1 hour to 2 hours, which greatly improved overall traction throughout the entire 8-minute runs for the remainder of the event.
For the first qualifier, I aimed for a user-friendly setup to ensure I could run the full 8 minutes without mistakes. I made the car more rounded for safety by widening the rear width from 171mm to 172mm and changing the side tubes oil from 10k to 12k. I used this setup for the first two rounds of qualifiers, and the car was incredible—very easy to drive and consistent. I completed both qualifying rounds without any mistakes and maintained a pace that kept me in the top 5.

Since we had four qualifying rounds with two counting, and after finishing 5th and 6th in my first two rounds, I felt confident I would make the A-main. I wanted to experiment with the setup to gain more steering and improve my speed. I was running only 0.4mm droop in the front, which made the car very stable and excellent for the chicanes. This change improved mid-corner steering, enabling me to push further. Unfortunately, I made a small mistake in the last qualifying round, dropping to overall 7th position for the finals. However, I was still thrilled to qualify so highly with limited race experience in this class, especially in such a strong field.

As traction increased throughout the rounds, the car became a bit too pushy in the finals. To regain rotation and steering, I made a few fine-tuning adjustments, reverting to 10k oil in the side tubes and narrowing the rear track width back to 171mm. In the end, I finished 6th overall and was very pleased with how the race went. Alexander Hagberg dominated the event, and Adam Izsay secured a strong 3rd place in modified and 2nd in stock class. In total, we had 6 cars in the A-main for modified and 3 cars in the stock class.
