White versus black playfield rubber

Rubber ring kits are sold per game; add flipper rubbers and a shooter tip if they aren't included. Black rubber, standard on most Williams games after about 1995, is harder and less bouncy but hides dirt. White rubber gives more bounce and a brighter look. Some games such as Scared Stiff were designed around black rubber.
