It's fastest Tamiya car on carpet. Far as oil, on 415 for rubber we were running 50F 40R with 2 hole pistons. Unfortunately I'll be running foams at Novak race, but 415 just rips on carpet with rubber. Way better then Evo3. Not sure about 4, since no one's runnnig one here locally. All local Tamiya cars are 415, running indoors on carpet with foam or rubbber.
do you mostly run the oneway, or a diff with rubber tires?
i ran the 415 most of this year, plus at TCS... lately, tho, i have had better success with the IV. thats why ill bring both!!!
