SICA17B Porsche 962C KH - #17 Jagermeister, 1st Spain 1986.

Easy, low-cost performance increase for Slot It GTP/Gp. C cars racing with magnets on plastic track...

Install SIPT06 19x10mm silicone slicks (a pair of these comes as extra tires with most of these cars) and an SICN07 racing magnet.  The tires slip onto the rear wheels and the magnet snaps into the chassis in place of the original magnet.  These two simple changes make a huge difference in the handling of the car and produce much faster lap times.
