Stärke Speedster Carbon Fiber "OUTLAW" With XR57 Engine : $175,000*

Sale price Price $175,000.00 Regular price


The Stärke Revolution Speedster OUTLAW is a tribute to the iconic cars of the fifties. The cars that were built by the drivers who didn't want to conform. Dean Jeffries is credited with developing the first "Outlaw" Speedster. With its extended fenders, sunken headlights and High Performance spec engine it made purists sigh and fellow hot rodders envious. Stärke continues this rebellious tradition with the Stärke Speedster Outlaw. This Speedster makes a statement from it's four inch wider body and lowered stance to the unmistakeable howl of the sport exhaust. Watch your rear view mirror... the "Outlaw" rides again.

If you're ready to drive the ultimate "Outlaw" Speedster than join the revolution. 

There are a handful of Speedster Replica company's out there. However, all of the Replica cars are the same in one important regard. They are all built by using a body on frame chassis design that is from the 50's and 60's. As you can imagine there are many limitations to these cars by their outdated design and engineering. But, with the Stärke Revolution 357 Speedster you can have the very best of both worlds. You get the classic iconic style inspired by the 356 combined with the modern performance, convenience, reliability and state-of-the-art engineering of a Porsche® modern day chassis from 1998-2012.

The Stärke is the first and only Speedster built on a modern Porsche® Boxster chassis with power top, 5 speed, Tiptronic or PDK automatic, ac, available Bose sound, power windows, cruise, stability control, cup holders, two trunks and so much more. The 357 is built on an authentic 100% Porsche drivetrain, not a VW or Subaru like the replicas. With Starke you can choose to buy your own Porsche Boxster from 1998 - 2012 that can be used as a donor car or we can locate the car for you and turn-key the build. Either way you can select a car within your budget and one that has the options you want. There is a large number of Boxster's out there in fantastic condition.
