Jim and Mike Ring, two halves of one of the world's most exciting and in-demand custom car building firms will be bringing three unique cars plus a Winnebago to this year's Speciaity Equipment Market Association show.

The first model the brothers will be unveiling is, or so they claim, the most daring project they've ever undertaken, and, considering that these are the guys that recently dropped a Chevy motor in a classic Ford Mustang, it's a huge statement to make.

The car in question is a 1948 Cadillac V Series fastback that takes the idea of restomodding to new heights. Nicknamed "Madam V," the car was stripped back to bare metal and two 2016 ATS-V Cadillacs served as donor vehicles as part of the build.

Madame V will meet her public for the first time on November 1 alongside "G-Code," the second new Ringbrothers show car. Starting out life as a 1969 Camaro, the brothers have turned it into the most powerful Chevrolet they've ever built, thanks largely to the Wenger Whipple supercharged LS3 motor under the hood. As well as upgrading the power, the car's lines have been thoroughly reworked.

It wouldn't be a Ringbrothers' show without a Ford Mustang, and so to appease fans while doing something different, on Wednesday, November 2, "Ballistic" the first convertible pony car the brothers have ever customized, will be making its debut.

The 1965 wide-body drop top boasts a 21st century supercharged 5.8-liter V8 powerplant from a GT500.

"SEMA is such a big deal for us every year," said Jim Ring. "We love having the chance to show the world all the hard work we put into these projects all year long and it's great to see all of our friends and fans."

And it will be great to see their expressions when the brothers showcase "The World's Fastest Winnebago." It's a 1972 Winnebago Brave with over 900hp under the hood and a "party-ready" interior inspired by WWII bombers.

"We're excited to debut these three new cars at the show," said Mike Ring, "and we know everyone at the show will get a real kick out of the Winnebago. It's going to be a great week."

This year's SEMA show runs November 1-4 at the Las Vegas Convention Center.
