The last part of the season opened on September 17th-19th at the Lonato circuit with the first of the two WSK Open Cup events. The official Parolin Motorsport team had changed its look for the occasion and adjusted to accommodate the arrival of young drivers. While Brando Badoer made his debut in KZ2, Enzo Deligny finished in the OK-Junior top five just ahead of Maksim Orlov, Christian Costoya shone in the Mini top five while newcomer Dries Van Langendonck showed great potential.

One week after Alfio Spina's Italian Championship in de OK class, another Parolin Motorsport driver was successful on the Sarno circuit.

For the launch of the WSK Euro Series at Lonato, the tough competition, especially in the rainy Final stages, made the meeting particularly challenging for the drivers. The return of Al Dhaheri meant victory in OK-Junior for Parolin Motorsport, while the performances of Celenta in KZ2, Rinicella in OK and Costoya in Mini showed the competitiveness of the team in all categories. Parolin Racing Kart was the most represented chassis brand in Mini and ranked second in all categories, while it was the only one to win in two different categories in Lonato with Parolin Motorsport in Junior and Baby Race Driver Academy in Mini.

The new Sarno track is still very fast, but it was a big change from the old Neapolitan track and again provided the setting for some tough battles. The Parolin Motorsport team confirmed its rise to prominence in KZ2 with the sustained presence of Celenta in the front ranks and Wharton's convincing debut in this elite category. Deligny finally registered his name among the best Juniors while Costoya and Orjuelas confirmed their roles at the front of Mini.

The Parolin Motorsport team played a major role in the WSK Champions Cup in Adria and intends to remain a strong team throughout the year. Competitive in all categories, the Italian team won the OK-Junior Final with the promising Emirati Rashid Al Dhaheri, while the return of an official Parolin-TM Racing team in KZ2 resulted in a remarkable performance by Francesco Celenta. In the icing on the cake, the Parolin chassis won in 60 Mini thanks to the Dutchman René Lammers from the Baby Race Academy team.

In the first change of 2021, the official racing team of the Parolin Racing Kart factory has changed its name to become Parolin Motorsport Srl, a racing team in its own right. After its numerous successes in Mini, OK-Junior and OK, Parolin will make its big comeback in KZ with strong ambitions. In total, this season the Parolin Motorsport team will include 18 drivers from 13 nations in the four international categories, while technical collaboration continues with the TM Racing factory.
