I have the stock foams in my rubber tires and the car is hooking up pretty good
when the tire temp is warm. I lowered the front to 4mm and the rear 3mm ride ht.so the rear sits lower and that helped more than a gallon of tire prep ever did. this is a cool time of the year and the kit tires need hot weather to warm up quickly. 85 deg. +++ would help. The new soft compound tamiya has will be the hot ticket.
My next set I will try to build with f103 rear inserts. I have also read on this fourm it helps and would like more fb too.
