Built, not bought
Our shop culture comes straight from racing. The builds on our wall aren't catalog cars — they're engineered, assembled and tuned right here, and our followers watch them come together week by week.
Porter's Performance is your LS/LT & Coyote expert — a performance and customization shop where "built not bought" isn't a slogan, it's the whole point.
Porter's Performance is an automotive customization and performance shop at 221 W. Lincoln Ave in Madison Heights, MI, known around metro Detroit as the LS/LT & Coyote engine expert. Instead of dabbling in every platform on the road, we went deep on two — GM's LS/LT family and Ford's Coyote modular — and mastered what makes them fast.
That focus shows up in the work: twin-turbo LS7 Corvette setups, 1,000 hp club builds, Shelby GT350R track prep, stroker engines with forged internals and custom cam grinds, and sequential transmission installs rated for 1,800+ ft·lb of torque. And when a build is done, our custom dyno tuning proves the result — like a naturally aspirated LS3 making 477 rwhp on 93-octane pump gas.
It's not all monster builds, either. The same hands that assemble stroker LS engines do pads-and-rotors brake service, lift kits, headers and cat-back exhausts. Small job or huge one, the standard is identical.
We're not the cheapest shop in metro Detroit — we're the one that builds it right the first time.
Every figure here comes off a real customer build — verified on the dyno or rated on the spec sheet, never guessed.
Answering the questions every owner actually has before handing over the keys.
Our shop culture comes straight from racing. The builds on our wall aren't catalog cars — they're engineered, assembled and tuned right here, and our followers watch them come together week by week.
Every build starts with your goal — power target, budget, street or track. We spec the parts, quote it straight, and you approve everything before work begins. No surprises on the invoice.
A build isn't finished until custom tuning extracts the power safely and the number is on paper. Talk is cheap; dyno sheets aren't. That's why we tune what we build.
Plenty of our biggest builds started as a simple brake job or an exhaust install. Wherever your car is on this line, we meet you there — and we can take it as far as you want to go.
Our social feed tells the story better than we can: it's dominated by high-horsepower Corvette C6 and Mustang builds, because those are the platforms this shop lives and breathes.
LS3, LS7 and the full LS/LT family — strokers, forged internals, custom cam grinds.

Whether it's a brake job on the daily or the twin-turbo build you've been sketching for years, the first step is the same: a no-pressure conversation about the car, the goal and the budget. You'll have a straight quote and a clear plan before anything happens — and we'll call you back within one business day.
