Thanks Nicknaz. I tried 31 psi and it seems a bit better and more planted but it didn't totally eliminate losing traction at wot. Will look up the Dunlop ZII.
The Porsche GT2, GT3 and 911 following the convoy are relatively new but not sure which generation they are. Tbh, they all look the same and I can't tell the difference.
Security is good. Have not had any problems in both Thailand and Malaysia. There's also a support car following the convoy at all times so no worries of mechanical problems too.
