The TrackStar 1/10 Touring Car Set-up Wheels have finally arrived! CNC machined aluminum parts with O-rings on the rim to keep your vehicle in place while you measure the setup. Suitable for 1/10 electric and nitro touring cars with 4mm axles for precision setup. The advantage of these setup wheels is the precision flat surface that allows your camber gauge rest precisely in contact. This makes setting up camber or even toe-in adjustments much easier, saving you time on the bench and at the track.
