Understatement, Amplified: The 911 GT3 Touring Manthey Kit

17% More Downforce. Zero Rear Wing.

The Manthey kit for sale achieves what seems impossible: significant downforce increase without the Touring's signature spoiler delete becoming a compromise.

An enlarged front lip works with additional underbody air-guiding elements and a flow-optimized visible carbon rear diffuser. Together, they generate 17% more downforce than stock—significantly improving vehicle controllability without disrupting the clean rear silhouette.

This is aerodynamics as sculpture. Function that enhances form. The Weissach wind tunnel doesn't lie, and neither does the Nürburgring. Every element serves a purpose. Every surface has been refined.

Proof that less visible hardware can deliver more performance.

Precision You Adjust in Seconds, Not Hours

The Porsche Manthey kit for sale includes a coilover setup that refuses to choose between street comfort and track precision.

Fully aluminum 4-way adjustable spring struts with adapted spring rates (+10% front, -7% rear) allow tool-free adjustment of compression and rebound at low and high speeds. A quick pit stop is all you need to dial in for conditions—or your mood.

Compatible with front axle lift systems. Developed across countless test miles. Because a Touring should tour comfortably, then transform when the track calls.

Performance and comfort. Finally, no compromise required.

Pedal Feel That Makes You Quicker—Proven on the North Loop

The Manthey kit for sale includes a brake line set with steel jacket that refuses to expand under pressure or heat. The result? Constant pressure, immediate feedback, faster reaction times.

Intensively tested by Manthey on the Nürburgring North Loop. Validated where braking zones separate the confident from the cautious.

Optional racing brake pads for gray cast-iron systems sharpen the package further—improved fade resistance, enhanced response, superior control. Developed specifically for track use, they maintain consistent friction across temperature ranges.

On the street, they're civilized. On the track, they're relentless.

Details That Reveal What This Touring Really Is

The Porsche Manthey kit for sale adds subtle signatures that signal sophistication to those who know.

Illuminated door trims in matte carbon with red and white Manthey lettering. LED door projectors casting white Manthey logos onto the pavement. Optional door graphics in white or black for additional individuality.

Optional towing loops in red, black, or yellow for track use—front and rear mounted, removable for street legality.

Understated doesn't mean unnoticed. It means noticed by the right people.

 16.1 lbs Lighter. Instantly Sharper.

Rotating mass is the enemy of response. The optional Manthey kit for sale lightweight wheel set cuts 16.1 lbs of unsprung and rotating mass—7.3 kg that transforms how the suspension reacts, how the car changes direction, how connected you feel.

Technologically optimized design improves spring-damper responsiveness and vehicle control. Available in brilliant silver, black silk gloss, dark silver, or exclusive neodymium.

Standard 20/21-inch fitment. Compatible with 255/35 ZR 20 front and 315/30 ZR 21 rear tires. Porsche recommends Michelin Sport Cup 2 R for maximum capability.

Less weight where it matters most. More connection where you feel it first.
