More Grip Starts with More Clearance

When you’re chasing performance, there’s no substitute for traction. Wider tires mean a larger contact patch, more grip, and ultimately, a faster, more confident car. But on most classic muscle cars, the limiting factor isn’t power - it’s space. Detroit Speed’s Mini-Tubs have been engineered to solve that problem the right way: with structure, precision, and geometry in mind.

A Purpose-Built Solution for Real Performance

Unlike traditional “cut-and-fit” approaches, DSE’s Mini-Tub Kit isn’t just about making more room. It’s about engineering that room with purpose. Each kit is designed around the idea that proper suspension geometry, body structure, and wheel alignment must work together, not against each other.

From the earliest CAD models to final fitment testing on real cars, Detroit Speed approached the mini-tub challenge the same way they do every component they make: an engineering-first mindset. The result is a system that provides up to a 335mm tire width (depending on model) while maintaining an OEM-style appearance, structure, and integrity.

Precision Engineering in Every Panel

Each DSE Mini-Tub Kit begins with laser-cut, stamped, and fixture-welded panels that replicate the factory curvature of the wheelhouse. This means every flange, contour, and weld location matches the car’s original geometry, ensuring seamless installation.

The inner wheelhouses are widened and reshaped, not just sliced apart - a critical distinction to ensure consistent tire-to-body clearance across both sides of the car. Reinforcement plates are included where needed, maintaining the strength and rigidity that classic muscle cars often lose during aggressive modifications.

Detroit Speed also developed custom templates and measurement guides for each kit, eliminating guesswork during installation. The result is a professional-grade modification that’s repeatable, reliable, and strong enough to handle modern tire technology and high-output engines.

Engineered to Work as a System

Where other mini-tubs stop at sheet metal, DSE’s solution goes further - it’s part of a complete performance ecosystem. Each Mini-Tub Kit is designed to complement Detroit Speed’s QuadraLink or leaf-spring rear suspension systems.

For Pro-Touring applications, this level of integration makes all the difference. The Mini-Tub Kit doesn’t simply make space for more rubber. Mini-Tubs help the chassis work in harmony with modern suspension and tire technology.

Built for Builders, Tested by Engineers

Every DSE Mini-Tub Kit includes all the essentials: pre-formed panels, closeout plates, frame rail templates, reinforcement patches, and detailed installation instructions. Designed for the experienced builder or the meticulous DIY fabricator, it offers the kind of precision that eliminates the frustration of constant test-fitting or body tweaking.

And because Detroit Speed develops and tests every kit on in-house vehicles, every curve and measurement has been validated through real-world testing and performance use. The same principles that define their suspension systems - repeatability, reliability, and strength - are built into every tub.

The Result: Room to Run

At its core, DSE’s Mini-Tub Kit is about unlocking the full potential of a muscle car’s stance and performance. Whether you’re building a ’69 Camaro with a QuadraLink, a Mustang ready for autocross, or a Nova sleeper that hooks hard and drives straight, the Mini-Tub Kit provides the space and strength to get the job done.

It’s not just about going wide. It’s about doing it the right way - with structure, symmetry, and speed in mind.
