This information comes courtesy of Motor Trend editor Jonny Lieberman, who broke the news on Twitter. In addition to the do-it-yourself gearbox, the 2015 SS will also reportedly use General Motors' excellent Magnetic Ride suspension – what's found on the Corvette, among other cars. That setup, combined with a proper row-your-own transmission, should make for one absolutely lovely SS.
When reached for comment, GM spokesperson Afaf Farah told Autoblog, "We have not made any new announcements about the Chevrolet SS." According to Lieberman's tweet, the updated SS will make its debut at the annual Woodward Dream Cruise in August.
