HERITAGE + INSPIRATION
A LEGACY REBORN. Imagine sliding into a cockpit designed over 75 years ago—only this one responds like a modern supercar. The 387 Speedster Heritage fuses classic Porsche flair with today's precision engineering.
Born in the 1950s, the original Porsche® 356 Speedster captured the hearts of driving purists with its stripped-back elegance and engaging road manners.
The 387 Speedster Heritage pays tribute to that legacy, while giving enthusiasts something its predecessor never could—modern-day drivability without compromise.
Our builds start with a Porsche® Boxster S as the foundation, reimagined with the stunning, retro-inspired 387 Speedster body. The result is a perfect marriage of classic style and contemporary precision.
