Speaking of ARV6's you should have seen Andrew Thompson's at Snetterton today. Leading from the beginning and lapping back markers well before the end of the 30 minute race with nobody else remotely close.
.
Andrews car also has 15bhp less than the other ARV6 that was running in second place
A well sorted car in the handling and braking department can certainly make up for small-ish power deficiencies, as you mention when the driver trusts the car 100% it becomes "chuckable", and of course great fun to drive fast.
