did some caluclations on the track maestro few weeks back

I know the maestro weight but guessed on cossie and scooby

Maestro 790kg = BHP Per Tonne 278bhp

Cossie 1300kg ish @ 350bhp =Per tonne 269bhp

Scooby 1600kg ish @ 420 =Per tonne 262bhp

All good just stopping, cornering and everything else is the issue
