Ringbrothers Carbon Fiber Coachbuilders LS7 Mustang Fastback

By Arison Knapp - April 25, 2016

Ringbrothers are widely-known in the auto industry for their NOS parts and even more for their SEMA winning complete builds like this full carbon-bodied 1965 Mustang. The Ringbrothers started their humble beginnings in Wisconsin as a collision repair and custom installation garage.

They gained their expertise doing OEM auto body work with many materials like carbon fiber with factory quality assembly as you can see in the pictures and video below. Soon they transformed to a classic parts fabrication resource and complete build speed garage. Annually they enter SEMA and other custom complete build-off competitions.

In the video below Jay Leno along with the two Ringbrothers do roughly a 20 minute walk-around design discussion resulting in a nice overview of the carbon Stang. It may be a bit hard to hear all the details about this 1965 Ford Mustang Fastback over the deeply credible throttle tones off the LS7 V8 engine so let’s see what parts the Ringbrothers chose for this specific build for last year’s SEMA show.

The centerpiece of the 2015 SEMA Mustang build was their own in-house developed custom full carbon fiber wide body kit. It’s specifically a 1965 Ford Mustang and about 4 inches wider than stock. The excellent first question from Jay to Jim and Mike was about the body weight difference. The carbon body is around 700 lbs. in reduction.

The Bros doctored the rest of the car with same top quality parts as their own. They went to Detroit Speed for four-corner coilover suspension system with a solid rear axle, Baer for braking, Whipple for supercharging and Tremec for transmissions. All this power componentry resulted in massively exciting power to weight ratio as well as peak power of 959 HP and peak torque of 858 lb-ft. The wide body kit is also available in fiberglass for $12,000 less but that won’t result in the power gains you get with the lighter carbon.
