anyone interested in tarmac rally's might be interested in one of 3 events held annually in New Zealand. 2 X 2 day events and a 5 day event. This years 15 aniversary is actually going to be a 6 day held in October. You can race or 'tour'. The tour is a social event where you drive the rally routes on closed roads but there is a lead car to keep speeds down to around 140kph which is plenty fast enough on tight windy back roads with no safety gear requirements (cage helmets etc). I just finished a 2 day event. Not in my Boxster - I'd rather not abuse that too much - but rather my WRX. There is a 986 Boxster in the field - fully prepped with hardtop fitted and several 911s.

Here is a pic from the weekend - felt like big air at the time but landing was reasonably smooth
