Air pressure difference can cause the rear screen to pop out of its seal / opening, especially if spinning or heading backwards.
These restraints are the solution to this problem. Laser cut from aluminium and CNC bent with a durable black anodised finish.

About 2.5 ST Look

Porsche 2.5 ST Look Conversion Kits - Classic Motorsport Widebody Style

Porsche 2.5 ST Look conversion kits recreate the aggressive, race-bred styling of the legendary early-1970s 911 ST—a car developed for endurance racing and wide-arch performance. Defined by its flared arches, lightweight panels, and purposeful stance, the 2.5 ST remains one of the most desirable classic Porsche competition looks.

At Design911, our Porsche 2.5 ST Look kits allow enthusiasts to capture this iconic motorsport aesthetic on later-model 911 platforms, blending authentic period styling with modern foundations, reliability, and usability.

What Do Porsche 2.5 ST Look Kits Do?

2.5 ST Look kits transform later Porsche 911s into wide-bodied, race-inspired classics.

Core Functions:

  • Replicate the distinctive wide-arch styling of the Porsche 911 2.5 ST
  • Replace standard body panels with motorsport-inspired components
  • Allow fitment of wider wheels and performance tyres
  • Enhance stance, grip potential, and visual presence
  • Create a historically inspired, competition-style Porsche build

These kits celebrate early Porsche racing heritage with unmistakable character.

Why Do Porsche 2.5 ST Look Kits Fail?

Not all ST-style conversions meet the expectations of serious enthusiasts.

Common Failure Causes:

  • Incorrect arch profiles that compromise ST proportions 
  • Poor panel fitment resulting in inconsistent body gaps
  • Inferior materials prone to cracking or distortion 
  • Lack of authenticity in styling details
  • Older kits lacking modern manufacturing accuracy

Low-quality conversions can diminish both visual impact and long-term value.

Why Replace or Upgrade Your 2.5 ST Look Kit?

Upgrading ensures authenticity, durability, and professional finish.

Upgrade Benefits:

  • Accurate wide-arch profiles true to the original 2.5 ST
  • Improved panel fit and alignment
  • Stronger, lighter materials for long-term reliability
  • Enhanced build credibility and resale appeal
  • A race-correct appearance that stands up to close inspection

Porsche 2.5 ST Look kits from Design911 are engineered for enthusiasts who value detail and heritage accuracy.

Highlights

  • Porsche 2.5 ST Look conversion components
  • Motorsport-inspired wide wheel arches and panels 
  • Precision-engineered for correct fitment
  • Suitable for impact bumper and classic-based 91 builds
  • Ideal for restomod and historic racing-style projects
