McLaren MP4-12C Spider Terso by FAB Design

FAB Design has applied its Terso body kit to the McLaren MP4-12C Spider, following last year's coupe version. The car seen in these photos was unveiled at the 2013 Tokyo Auto Salon showcasing a body kit featuring bigger air intakes, updated side air intakes, side skirts, diffuser and rear bumper. It has a new rear spoiler which is installed over the top of the stock unit. There's also a front splitter mounted below the windscreen, just like in the coupe. It sits on 20-inch FAB-Design Evolution forged wheels covered by Dunlop SP SportMaxx tires. Other changes include a proprietary stainless steel sports exhaust system and a three-chamber carbon tail pipe which have increased the output from 616 hp (460 kW) to 680 hp (507 kW). Most likely, other hardware changes (like an ECU upgrade) were necessary to reach this output.
Thanks to these tweaks, the McLaren MP4-12C Spider Terso reaches 62 mph (100 km/h) in three seconds and can hit a top speed of 213 mph (343 km/h). FAB Design said they plan on making only 10 units.
