NOTICE FROM SLOT IT ABOUT THIS CAR: 

"Dear Customer,

We have discovered a quality issue in the front wheels of some cars which may affect your product. This applies to some SICA10D and SICA12B shipped to the USA and Australia. You might find that the  front wheels are not as round as you would expect from our product. If this is the case, please replace the original parts with one or two of  the supplied spares.

First, check whether your car's front wheels are properly working by running the car on the track or spinning them by hand. An unexpected  vibration is the symptom to look for. 50% of the cars could be affected.

Using a screwdriver, remove the body of the car. Grab the front wheels  and twist them so that one of them will come off the axle. Make sure  you don't loose the 'cup' separators which separate the chassis and  the front axle. Remove the offending wheel(s) from the front axle and  replace them. Reassemble the car.

We apologize for the problem caused.

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. 

Need more grip?  Try these aftermarket tires!  Supertires 1400, 1401, 1402. 1403, 1404, 1405
