Destiny have introduced new option parts for the RX-10S 4WD touring car. First up is a progressive shock system that utilises a common design. Alloy inserts with triangular cut-outs and solid shock pistons make for progressive shock action on damper compression as the holes the shock fluids travels through become smaller while the pistons move up during compression. The tubes come black anodised for wear while the machined pistons offer high precision for even shock action. The set includes four inserts and four pistons and it is best used on asphalt tracks where it can add drivability and traction. Also new are 4mm aluminium wheel hubs with laser-etched markings for easy identification as well as aluminium diff cams as a replacement for the standard composite parts. Both the hubs and cams come in sets of two pieces.
