You spent $400+ on the retracts. Now go to Aerotech or Sierra and buy a NICE set of scale wheels. The Aerotech wheels are narrower and fit in the wheel wells perfectly. Daroll at Sierra sells the Aerotech wheels to compliment his gear. When your model is setting on the main gear for the first time you will appreciate the extra money you spent on the wheels. Nice wheels are like a new suit. It always looks better with a nice new pair of shoes. You do not wear tennis shoes with a Tuxedo! Do not buy wheels with a non metallic hub or center.
