"The team will also form a partnership with Shell V-Power Racing Team, racing one of their Ford FG-X Falcons that has been freshly rebuilt for next season." -- That's a worry (rebuilt = fitted with various left over bits?)... But given MSR's excellent relationship with DJRTP, it will probably be a rocketship and indeed better than current 888 Commodore.
It does seem a risk to abandon the 888 Commodore for other equipment -- are they getting shocks and other go-fast tweaks from DJRTP?
