Gunther Werks Reveals Its Most Track-Focused 993 Yet

At Monterey Car Week, California-based Porsche remastering specialist Gunther Werks unveiled the GXR-Evo, a limited-run reworking of the 993-generation 911 that prioritizes track performance over the street-focused character of its earlier builds.

The car begins as a late-model 993 911 that is stripped to its chassis and rebuilt with a full carbon-fiber body, aerodynamic dive planes, a Le Mans-style vertical stabilizer, and a large rear spoiler. In place of the original powertrain sits a 4.0-liter air-cooled flat-six developed with Rothsport Racing, producing 455 hp at 9,000 rpm and 312 lb-ft of torque, mated to a rebuilt Getrag six-speed manual and a limited-slip differential.

Gunther Werks says the carbon construction keeps curb weight below 2,400 pounds, giving the car roughly 5 pounds per horsepower. The chassis package includes JRZ three-way adjustable remote-reservoir dampers, Brembo Pista race brakes, magnesium wheels, and race-spec cabin equipment such as a carbon-Kevlar seat, six-point harness, eight-point roll cage, helmet cooling, and a fire suppression system.

Only 15 GXR-Evo units will be built, and each will include a matching custom racing simulator rig from MYSIM. Pricing was not disclosed in the announcement.

Why the GXR-Evo Is More Than a 455-HP Restomod

Where Gunther Werks is positioning the GXR-Evo

The company already competes in the high-end remastered 911 space, but its previous cars were described as street-oriented. With the GXR-Evo, Gunther Werks is making a deliberate move toward the ultra-track-focused end of the market, using a manual gearbox and air-cooled engine to appeal to buyers who want an analog experience that modern Porsche GT cars cannot replicate.

The power-to-weight comparison matters more than peak power

At 455 hp and under 2,400 pounds, the car’s claimed 5-lb-per-horsepower figure is broadly comparable to a modern 911 Turbo S, according to the company’s math. However, the GXR-Evo’s significance is less about outright output and more about how the power is delivered: a high-revving naturally aspirated engine, rear-wheel drive, a manual transmission, and a stripped cabin create a driving character distinct from faster but heavier turbocharged and electrified alternatives.

The 15-unit run turns the reveal into a scarcity event

A production run of 15 cars is small even by restomod standards, which reframes the announcement as much as a brand statement as a sales program. The inclusion of a MYSIM racing simulator with every car is also notable: it signals that Gunther Werks expects owners to use the car in anger and wants them to learn its behavior before taking delivery.

What Prospective GXR-Evo Buyers Should Know

For prospective buyers and collectors:

  • The run is fixed at 15 cars, and the MYSIM simulator is included in that package, not an added option, according to the announcement.
  • Because the GXR-Evo is presented as race-focused rather than street-focused, buyers should clarify road-registration and warranty terms before committing; the cabin’s roll cage, fire suppression, and air-jack hardware point to a car intended primarily for track use.
  • Final pricing was not disclosed, but the specification places the car at the high end of the remastered 911 market, so interested parties should compare it against Gunther Werks’ previous builds once pricing is published.
  • The car’s specialized components mean service and parts support from Rothsport, Brembo, JRZ, MoTec, and Getrag supply chains should be part of any ownership plan.
