Hydro-Boost Brakes
Nothing is more terrifying than cruising down the street to the fairgrounds when some idiot pulls out in front of you and you have to jump on the binders. Making a panic stop can be difficult when you are trying to stop 800 throbbing horsepower with a set of 9-inch rotors and single-piston calipers. You might even wonder if it will stop as you mash the brake pedal. When it comes to street rods with big motors, one braking concern is vacuum pressure. Is there enough? Many high-performance camshafts add power to the motor but produce low vacuum levels. This is something to consider when selecting your engine components. Of course, if the motor fails, you will have no vacuum, so stopping will be a real problem.
Product Spotlight: DIESELSITE 17-Row COOLERMAX Transmission Cooler
Rated at a monster 59,000 BTUs, this cooler doesn’t just compete—it sets the bar. Standard factory units limp along at 15k–30k BTU. Even most “heavy-duty” aftermarket coolers top out well below the COOLERMAX’s rating. That extra capacity can mean the difference between cruising safely at 180° or cooking at 240°. In the real world, that translates into drops of 50–60°, longer fluid life, and transmissions that simply last.
HPX 2026 Puts Education in the Driver’s Seat of the Automotive Industry
The High Performance Expo isn’t just coming back in 2026—it’s doubling down on what made the inaugural event hit so hard in the performance aftermarket world. HPX 2026 has officially unveiled a stacked education lineup for this year’s show in Charlotte, North Carolina, bringing together shop owners, racers, manufacturers, builders, executives, and industry disruptors under one roof for three days of high-octane networking and next-level learning.

Their Work Wins — At the Highest Level
You don’t land in the winner’s circle by accident. Pyramid helped craft the headlights and taillights on the 2025 Ridler Award–winning ’55 Chevy Nomad “Gray Madder.” When the top award in custom car building is on the line, builders choose Pyramid — because their design, engineering, and execution deliver championship-level results.
And it’s not just cars. Pyramid even fabricated the Big Oak Garage Celebrity Pick trophy for the Triple Crown of Rodding, proving their talent scales from precision components to industry icons. If it needs to look incredible and function flawlessly, they’re the ones trusted to build it.
The RMS Camaro goes Commando
On the RMS Customs ‘69 “Commando” Camaro, Pyramid didn’t just contribute—they helped define the car’s identity. Their custom full-housing taillights are engineered with precision: no LED bleed, crisp illumination, and a plug-and-play fit that looks factory-born but unmistakably modern. RMS trusted Pyramid not only for the part, but for how the part integrates into the Camaro’s aggressive redesign. That’s what Pyramid Optimized Design does best: they create harmony between vision, function, and form.
Full-Service Design That Goes Beyond Parts
What sets Pyramid apart is their broad suite of custom automotive design services. They can step into any stage of a build and elevate it. Sketching, scanning, engineering, prototyping, production — everything driven by deep technical chops and creative horsepower.
Whether you need carbon fiber bodywork, intricate lighting, a complete interior redesign, or a one-off component that’s never existed before, Pyramid’s process blends art and engineering in a way few shops can match.
Capabilities That Turn Dreams Into Reality
Pyramid’s capabilities read like a dream wish-list for any serious builder. They leverage industry-leading 3D scanning, advanced reverse engineering, and full CAD development, backed by both 3-axis and 5-axis machining for precision component creation. Their 3D printing arsenal covers FDM, resin, and metal printing, giving them unmatched flexibility in prototyping or producing final parts. When a project calls for production-grade materials, they offer injection molding, plastic casting, sand casting, and investment casting, allowing them to engineer components in whatever medium the build requires. And when things need to be welded, shaped, or handcrafted, their TIG and MIG welding, wheel design and manufacturing, suspension engineering, chassis design, and full in-house fabrication ensure that even the wildest concept can be brought to life with precision and style. This isn’t just a parts shop — it’s an entire innovation ecosystem.
Bring Your Vision to Life
Got something in your head that feels “too crazy” for most shops? Perfect — that’s where Pyramid Optimized Design does their best work. Their blend of 3D scanning, CAD engineering, precision machining, 3D printing, casting, welding, and fabrication gives them everything they need to take napkin sketches all the way to award-winning hardware.
Whether you’re crafting custom lighting, rethinking a chassis, engineering a suspension system, or developing a bespoke part that only exists in your imagination, Pyramid has the technology and the talent to turn it into reality.
Your build deserves more than off-the-shelf solutions. It deserves a partner that can dream with you — and then engineer the dream into metal.
