While he admits the organisation of the grand meet opening will keep Masterton Motorplex club members "extremely busy" over the next few days, Wilton said a "test and tune" event a couple of weeks back had provided an excellent learning experience in that respect, and he was not expecting any problems.
"About the only worry we might have is catering for all the cars in the pit area.
"I think we might be close to maximum usage there.
"It's a good problem to have though, isn't it?"
Saturday's action, which will include the track being officially opened by a representative of major sponsors, Trust House, will get under way at 10am and most of the racing that day will act as qualifying for the finals to be held on Sunday.
