Typically know for tuning Lamborghinis, Renown Auto Style has turned its hand this time to the Mercedes-Benz SL-Class, creating a wide-body package dubbed the R230 Sidewinder. The package makes the roadster ten inches wider than the SL65 Black Series and an inch wider than a Murcielago. It consists of front and rear bumpers, hood, side skirts, front fenders, rear-quarter panels, trunk spats, rear diffuser, wheel well liners and a new water tank. A choice of 3-piece concave alloys include the 20" Renown RX10-C wheels featured here.

An optional upgrade package adds a front lip spoiler, side skirts, skirt vents, bumper vent, diffuser and wing - all made of carbon fiber - as well as original Mercedes foglights with a carbon-fiber light bar. The body parts are made using vacuum-bagged fiber-reinforced plastic sheets produced with an epoxy resin system. All products include a Lifetime Protection Plan that enables owners to replace damaged parts for 50% of the MSRP.
