The Ferrari 499P Le Mans Hypercar will run 5kg heavier and with maximum power reduced by 12kW or 16bhp from the levels at which it won the double-points round of the WEC last month with Antonio Giovinazzi, Alessandro Pier Guidi and James Calado.
Toyota, which finished second and 1m21s in arrears of Ferrari in the 24 Hours, has an unchanged weight for the Monza 6 Hours on 9 July and will run with 5kW or 6.7bhp less maximum power.
