The recent tests, conducted last month, garnered insights from Frey-Hilti, who leads a GT racing stable specialising in Ferraris.
Verstappen's manager's son, Thierry Vermeulen, contributed to the initial steps by participating in GT racing events with a Verstappen.com-sponsored Ferrari 296 GT3, showcasing impressive podium finishes and exceptional qualifying averages.
To have Verstappen is 'an honour'
Verstappen himself tested the new Ferrari for the new GT season at Autódromo Internacional do Algarve in December.
“The aim of the test with Max was to support Thierry and also improve our performance with his feedback,” Frey-Hilti explained to Motorsport-Total.com.
"He rode on both days. On the first day it was about a hundred laps and they took turns. We tried a lot.
"It feels like an honour for us that he uses our services as a racing team and that we are able to to work with him on the test days. It's really brilliant."
