It turns out that the Toyota 86 GT has amazing potential. This run was performed by none other than IGOR; Australian time attack hero, in a short one hour session with the 86. I included his best splits for the session at the end of the video, as well as below.
CP1: 34.454
CP2: 37.320
CP3: 37.782
CP4: 36.323
Total: 2:25.879
Japan’s record with the 86 on Hakone Inbound is 2:25.804, so he’s not far off!
