Right now I've been using the Pink/Purple combo but I think I still have too much front even with no sauce on the front and full on the back. The Contact are surprisingly good for how cheap they are. I tried CRC Green and Blue rear with blue and double blue fronts and they did not have any rear traction for our carpet. The really fast guys use Pink rear and find a front that works for the day. I'm kind of new to 1/12 and this skittles rainbow of colors and options is frustrating for running 17.5 1/12 spec racing. I wish they would spec a tire or run the CRC Purple stripe spec tires and call it good. I'm tired of spending so much $$ just trying to find something that will work good and consistent on this carpet.
