I remember doing that in my first 240z racecar. Drive to the track, take 4 rims that were well placed around the cage and passengers seat, swap these for the road rubber change the koni shock settings then race for the day and drive home once the day was over.

I have a feeling I will be doing the same with the current project too as I don't have a trailer and the cost of one is almost a season of race entry fees

I do recall all those cars I mentioned running in the late 80's at the Whenuapai Taccoc days. Those were some great racing as I recall with a good mix of cars.
