When it comes to restomodding, especially American classics, nobody does it better than Ringbrothers. The custom car builder based in Spring Green, a small town in Wisconsin, has shown many stunning automobiles in past SEMA shows and have even had several of their builds commissioned by OEMs. This year, the custom carmaker is bringing four special restomods to the SEMA show based on a Cadillac, Chevrolet, Ford, and Winnebago.

The Cadillac, which is a 1948 Series V fastback, was originally built for Wes Rydell and his wife Vivian. Ringbrothers customised the 1948 Cadillac’s steel body and used two brand new 2016 ATS-V Cadillacs to create a blend of the vintage and the modern. Named “Madam V”, it will be the first to be unveiled at the SEMA show on November 1, 2016.

Next is the “G-Code” Camaro, the second 1969 model the Ringbrothers have built. With a Wegner Whipple supercharged LS3 under the bonnet, this Camaro is also the fastest and most powerful Chevy they’ve customised, although they haven’t divulged the official performance figures.

Joining these two will be the “Ballistic”, a 1965 widebody Mustang convertible powered by a supercharged 5.8-litre V8 engine taken from a GT500. Although the Rings have built many a fastback Mustang over the years, this is the first time they’re working their magic on a convertible.

Then there’s the “World’s Fastest Winnebago,” a 1972 “Happy Camper” Winnebago Brave that’s been transformed into a 900+ horsepower hyper RV.

“SEMA is such a big deal for us every year,” says Jim Ring, co-founder of Ringbrothers. “We love having the chance to show the world all the hard work we put into these projects all year.” Meanwhile, his brother and co-founder Mike Ring said although they’re excited about the three new cars, it’s the Winnebago that showgoers will “get a real kick out of.”
