World Record holder the "Bullet" AMG GT63 built by RENNtech

RENNtech's Modern Icons:
We at RENNtech were thrilled to bring a few of our own performance machines to the show, including “The Bullet,” a 2019 Mercedes-Benz AMG GT 63 S. With 1200 HP and finished in striking Graphite Magno with Lite-Speed Gloss Black Magnesium wheels, “The Bullet” broke the gas-powered world record with a 9.79-second quarter mile at 1000 feet, earning recognition in the DuPont Registry, and won the Swan Award in the 2000's Mercedes-Benz category.

AMG GT R3 RENNtech's Official Development Vehicle

Another crowd favorite was our official RENNtech Development 2017 Mercedes-Benz AMG GT. Used in our R&D for the AMG GT (C190 -chassis), this vehicle is the foundation for developing high-performance upgrades including engine components, exhaust systems, suspension, and aerodynamic parts, delivering an impressive handling and 750 HP and 650 lb-ft of exhilarating performance.

RENNtech’s Legacy and Leadership:
RENNtech owner and founder, Hartmut Feyhl, joined us at the show, engaging with attendees on our cars' engineering and history. Feyhl’s journey began at AMG in Affalterbach, Germany, where he contributed to the legendary W124 AMG E300 6.0 “Hammer.” After launching RENNtech in 1989 with the support of AMG founder Hans-Werner Aufrecht, Feyhl has dedicated RENNtech to delivering “Performance Without Compromise.”

Mercedes-Benz 540K Spezial Roadster

A Historic Display from Mecum Auctions:
One standout was the 1936 Mercedes-Benz 540K Spezial Roadster, brought by Dana and Patti Mecum of Mecum Auctions. With its Sindelfingen “High-Door Long-Tail” Coachwork, this car was originally owned by Baroness Gisela Von Krieger for 50 years and achieved a record $11,770,000 sale at the 2012 Gooding & Company’s Pebble Beach Auction.

Lake Mirror Car Show 2024

A Thank You to the Lake Mirror Classic Team:
Our thanks to Robert D’Angelo and the incredible volunteers who brought this event to life, even after extensive flood recovery efforts around Lake Mirror. It was a fantastic weekend, and we’re already looking forward to next year!

Introducing RENNtech Track Series Forged Wheels

AMG GT R with RENNtech Track Series 19 x 10" front and 20 x 12" rear wheels with Satin Titanium finish.

RENNtech RTS Forged Aluminum Wheels are the latest addition to a legendary line of RENNtech performance wheels.

It all starts with an idea: The right wheel for the right situation. RENNtech Track Series wheels exemplify RENNtech's philosophy of bringing Motorsports Technology to the Streets and were created to be the perfect wheel for performance and track driving.

RENNtech's product development team set out to deliver a track-oriented, light weight forged aluminum wheel featuring innovative technology and sophisticated design. Engineered for rigorous track use, RTS wheels are packed with functional design elements for improve structural integrity and maximum weight reduction. The refined design aesthetic follows the current Mercedes-AMG design language with visual cues to pre-merger AMG, making the RTS a perfectly balanced wheel for driving on track and the streets.

Initial Design Concept: Inspired by AMG heritage

Design Development: 3d CAD model

Design Review: 3d printed prototype

Engineering: Finite Element Analysis (FEA)

After confirming the technical viability, several design concepts were explored, refined, and translated into CAD to create the first 3D printed prototypes for visual reviews. From these prototypes, combined with stringent engineering analysis of the CAD models, including Finite Element Analysis (FEA) software validation before the final production version emerges for fitment and real-world testing.

Rigid Spoke Tracers were incorporated into the spoke profile for improved structural integrity while reducing the overall weight of the wheel. A Reinforced Inner Rim Flange was integrated to better withstand wheel deflection / deformation under high load situations, resulting in improved driving performance and consistency on track.

Aluminum Wheel Casting vs. Flow Formed vs. Forged

RENNtech has strategically partnered with industry leaders Titan 7 Wheels for development and production of the RTS wheel.

"Titan 7's extensive experience in manufacturing track focused wheels combined with their forging expertise and their complete in-house production gives us a high degree of control in the production process. This way we can deliver a wheel of the highest quality and consistency that RENNtech is known for, and our customers have come to expect." said Hartmut Feyhl, President RENNtech Inc.

Each wheel starts out as a solid cylinder of aircraft grade 6061 aluminum. These cylinders are pressurized with 10,000 tons of pressure to improve the grain structure and overall properties of the aluminum to obtain the wheels initial shape and dimensions. The result is a CNC machine ready forging which features no porosity and a densely organized micro structure for an incredibly strong and lightweight wheel.

Launched for AMG GT (190) -series and AMG E63 (213), additional model fitments will follow in the coming months. The wheels are available in two finishes, Machine Black or Satin Titanium, along with two RENNtech Design center caps or OEM MB AMG center caps. The RTS wheels are covered by a lifetime structural warranty, allowing you to enjoy the groundbreaking performance of your Mercedes-AMG with confidence, on track and on the streets.
