I miss typed the tire selection. Shore 40 on front and shore 20 on rear. I would like to have snow tires like the car came with from Scalextric, but those stock tires are soft, so not ready for the front without nail polish. I may resort to nail polish and stock tires with nail polish on front. I have not run the nail polish fronts before. It has been a problem to find aluminum wheels and urethane or rubber tires for the narrow tire class Mustang and Austin Mini Cooper. I wanted something to glue on and true nicely.
My second thought was maybe the long Mustang will need harder than 20 shore rears to easily drift the sharp corners. The tire issue is big for me and I beg the micro circuits to operate our rally track again.
