Coming from Revolution Design Racing Products are the new Brass RF and RR Suspension Mount for the Xray XB2 series of cars. They are a direct replacement for the kit's lightweight parts and adds valuable weight especially when running in low-traction conditions or when the track is getting bumpier. Machined from black-coated brass and sporting gold-colour chamfered edges the parts weighs in at 12g (RF) and 15g (RR) which shifts the weight bias further back for improved traction and a more planed ride when running on bumpy tracks. The RR suspension mounts fit all XB2 series cars and trucks except for the XB2D'17, they are available separately and can be used together or in a mix with the standard mounts to achieve the desired weight bias and driving feel.
