Former WEC GTE Pro sparring partners Bruni and Tincknell will give Proton Competition's US-based Porsche 963 its debut at Road America on 6 August, just four weeks after they drive the sister car in the WEC’s Hypercar class for the first time at Monza at the beginning of July.
Proton boss Christian Ried told Autosport that it made sense to have the same drivers for the team’s two LMDhs as a result of its late start to its twin programmes in the WEC’s Hypercar class and GTP in IMSA.
