1,190 lbs. of Downforce.

This Is Why You Buy the Manthey Kit.

You didn't search for a Porsche Manthey kit for sale to blend in. You searched because you want to own every corner.

At 177 mph., the Manthey aerodynamics package generates 1,190 lbs. of pure, pavement-sucking downforce. The carbon rear wing with integrated Gurney flap and slanted end plates isn't just visible aggression—it's precision airflow management. The extended rear diffuser with longer carbon fins transforms turbulent air into additional grip without the drag penalty that ruins top-end speed.

The front lip extends 12mm farther than stock, working with front diffuser fins and dual flics to create aerodynamic balance that neutralizes understeer. Result? Higher cornering speeds. Later braking points. And the confidence to push harder than you ever have.

This isn't styling. This is physics working in your favor.

The Secret Weapon Underneath Your Porsche

Real motorsport enthusiasts know: what you can't see often matters most.

When you invest in your Manthey kit, you're getting the most efficient underbody engineering to ever carry the Manthey label.

150cm turning vanes run the length of the underbody, generating downforce that's neutral across all driving conditions. Every surface has been smoothed, every contour optimized to feed these vanes perfect airflow. The result is constant downforce whether you're trail-braking into a hairpin or flat-out through a kink.

Porsche and Manthey didn't just bolt on parts. They reimagined what a GT3 underbody could be—using development DNA from the record-breaking 911 GT3 RS (Type 992.1) Manthey Kit.

You won't see it from the driver's seat. But you'll feel it in every high-speed transition.

Coilover Suspension

That Adapts to the Track—and to You

Track conditions change. Your driving style evolves. The Porsche Manthey kit at Champion Porsche includes four-way adjustable coilovers that change with them.

These aren't off-the-shelf dampers. They're aluminum-bodied, motorsport-grade units with tool-free adjustment of compression and rebound at both low and high speeds. Developed across countless test laps and driving dynamics sessions, the setup delivers precision without punishing you on the drive home.

Spring rates shift +20% front, -7% rear compared to stock—subtle numbers that transform behavior. The front digs harder. The rear rotates more predictably. The balance? Pure confidence.

With or without front axle lift, we've got your setup covered.

The Braking Advantage

That Shaves Seconds, Not Just Meters

In motorsport, the race is won between the braking point and the apex. The Manthey kit gives you the tools to own that zone.

Stainless steel-sleeved brake lines eliminate the spongy pedal feel that kills confidence. The response is immediate. The feedback is honest. Pair them with trackday-specific racing pads that laugh at fade and maintain stable friction across temperature swings.

Modulation improves. Reaction time drops. And suddenly, you're braking later than your competitors—every single lap.

Low disc attack means these pads play nice with your rotors. High performance doesn't have to mean high maintenance costs.

Details That Remind You—This Is No Ordinary GT3

The Porsche Manthey kit now for sale doesn't just transform performance. It announces itself.
