This TSR chassis is designed for use on commercial or club wood tracks on which traction-enhencing compounds are used. This TSR Club chassis kit features front independently-rotating aluminum wheels, setscrew rear aluminum wheels, neoprene-foam tires and setscrew alloy spur gear.
It is recommended to add thin self-adhesive lead weight over the steel pan to bring the total weight of the car to as much as 4.5oz or 125 grams for best performance without traction magnet.
-Use with or without traction magnet.
-The use of a min. 2-amp variable voltage power supply and PM electronic controllers is highly recommended. Note: not suitable for plastic track as traction would be inadequate.
