Both GT4 races counting towards the 2018 Italian Gran Turismo ended with the Ginetta of Matteo Cressoni and Luca Magnoni in front of the sister car of Henri Kauppi and Alessandro Marchetti. The script of the Misano Adriatico races was almost the opposite, with the "family feud" more lively at the beginning on Saturday, on Sunday instead the final provided some twists. Finland's Kauppi started race one ahead of Magnoni and remained there for thirteen laps before the Varese, Italy-based driver handed over the wheel to Cressoni. The latter pushed hard through the eighteenth lap, then overtaking Marchetti, who in the meantime had replaced the North European driver.

Sunday race saw Cressoni safely control the GT4 class operations from the start, ahead of Marchetti for sixteen laps. At Misano you could only find four drivers out of 32 in the field that made the choice to stay behind the wheel for a full hour, and two of those were Cressoni and Magnoni, who had entries in both GT4 and GT3 Light exchanging the steering wheel at midway. As Sunday marked the first real summer day that the Italian GT drivers had to face, at the end of the GT4 race the orange Ginetta of Kauppi challenged the black sister car with Magnoni at the wheel, as the young Finnish had a lesser burden of fatigue than the team mate. However, Magnoni grinded out to win for the fifth time in six races, finishing six seconds ahead of his team mate.

The two races at the wheel of the Audi R8 LMS ultra had in store way more twists for Cressoni and Magnoni. The former F.3 champion preceded at the start the Ferrari 458 of archrival Marco Magli, an amateur driver who is renowned for not taking no as an answer and he managed to take the lead on lap six from Cressoni. It was a brief relief for the Ferrari driver, who spun off track on lap later. However, this did not put an end to the GT3 Light class story: when Magnoni replaced his colleague, the clutch started to give up, forcing him to slow down and stop. The distance traveled by the Audi before returning to the pits was enough, however, to ensure the drivers of the white R8 LMS ultra could rack up 20 points. On Sunday Magnoni started in front, but from the second lap Magli took the lead and never looked back, albeit Cressoni putting in a collection of fast laps managed to shave the final gap to six seconds, so claiming the final spot in the overall Top10.
