well I finally ran my rrr wce saturday and I must say this is a awesome car. I havent raced nitro touring for years and this car made me look like a expert. Im very happy the way this car drives. Only a couple small setup issues. The rear seems to be a little loose in some corners exiting, another small issue seems to be in 2 turns exiting the corner the front wants to push a little. Right now the car is box stock. Setup to the wce setup sheet, Also the tires are the ones Im using from the kit and they havent been trued. Should I go to a like 70 or 80 weight oil in the front, and drop to 50 in the rear? Or should I leave it alone. Would appreciate any advise. Thanks. Also I noticed since the tires arent trued that the rear tires since running 5 tanks are smaller than the front tires now, is this normal? Meaning the diameter
