Tech Report from Hudy Series Slovakia Round

Last weekend, I participated in Round 4 of the Hudy Series Slovakia in the Touring Stock Spec class. I didn’t have much time to practice, as I was very busy with office work after returning from TITC. Therefore, I decided to use my ETS Daun set-up, which worked really well there. I only made a few minor adjustments to adapt the car to the smaller track and the Hudy tires, which are more round and generate more traction.

With just a few small changes, the car was working very well. Many drivers asked me for the set-up sheet, so I decided to write this short tech report.

As mentioned, I started with my ETS Daun set-up, where I used the steel chassis with short arms. The reason is simple: the steel chassis provides great stability, makes the car very easy to drive, and reduces traction rolling compared to the aluminum chassis. Because of the improved stability, the car can feel slightly lazy, so I used the short arms to regain steering response. With the short arms, the car became more aggressive and offered better in-corner steering.

The Daun layout was quite large, with many high-speed chicanes. For that reason, I used a 1.3mm front anti-roll bar to reduce excessive front roll and prevent the car from diving too much on corner entry. At Hudy Arena, however, the layout is much tighter, so to gain more mid-corner and low-speed steering, I switched to a 1.2mm front anti-roll bar.

Since the Stock class requires a lot of corner speed, I prefer using the -1mm upper clamps. This gives the car slightly less initial steering but significantly more mid-corner steering — which I personally prefer. To regain some initial steering response, I moved the front wave brace from the bulkheads to the top deck. I really like this option on small, tight tracks. On bigger, more open tracks, I prefer running the wave brace in the original bulkhead position.

Because I was using the steel chassis and the Hudy tires are very easy to drive, I also preferred running more droop both in the front and rear. More front droop provides additional mid-corner steering, while more rear droop increases off-power steering.

The car was very easy to drive and fast at the same time — the perfect combination. This would also be my starting set-up for the Mibo International race.
