Coming from JConcepts is the S1 body shell for the Yokomo YZ4-SF 4WD buggy. One of the most recognisable items, the Silencer body style, has now been designed as the original manufacturer kit body for the Yokomo YZ4-SF buggy. It features the common Silencer attributes such as a profiled cockpit and cubicle side-pods, a slight recess just behind the cab with channeling out the rear, and the side-pods have a clipped rear-end, narrowing the rear by angling in just in front of the rear tyres. The main pods are lightly chamfered front and rear allowing plenty of paint and decal access. The end result has the body looking extremely low-profile with heavy JConcepts edginess and appeal. The Silencer is capped off with a cockpit shark fin for more high-speed tracking stability and increased roof stiffness. The package includes two S-Type wings pre-marked for the Yokomo YZ2 and YZ4-SF for the easiest application. Also the body has two cut lines to choose from. The most open cut line can change the performance or aide in the cooling inside the body. The more aggressive (larger opening) cut line is preferred on outdoor tracks or where ambient temperatures are really warm.
