[1] He debuted in the World Rally Championship driving a Renault 5 GT Turbo at his home event, the Rallye San Remo, in 1986.

For the 1991 season, Aghini got a contract with the Lancia-supported Jolly Club team for two WRC events; the Sanremo and the Rally Catalunya.

He finished sixth at the Tour de Corse, and then edged out his team-mate Juha Kankkunen to take his first and only world rally win in Sanremo.

After Lancia withdrew from the WRC, he moved back to Jolly Club to partner defending world champion Carlos Sainz.

In 1994, Aghini partnered Kankkunen and Didier Auriol at the Toyota factory team in a few events and finished third at the Tour de Corse with a Celica Turbo 4WD.
