Carbon fibre rear bumper diffuser.

Fits
Porsche 987 Cayman - 2005 to 2012 (Gen 1 and Gen 2)

Rear diffusers are extremely efficient downforce producing devices when designed properly. We set out to produce a functional rear diffuser for the Porsche 987.1 and 987.2 using state of the art R&D processes. The assembly blends function and form utilizing carbon fiber, sheet metal, and hard rubber.

Utilizing scan data, CAD, and ANSYS Fluent analysis software; we were able to design and produce a functional and aesthetically pleasing rear diffuser for this Porsche chassis.

The three main diffuser planes are produced from 2x2 twill, autoclave cured, carbon fiber; while the strakes are manufactured from durable polyurethane for longevity.  

The entire unit bolts to chassis locations through multiple sheet metal brackets. There is absolutely no drilling or fabrication required for installing this rear diffuser.

适合
保时捷 987 Cayman - 2005 年至 2012 年

继保时捷的初衷之后,我们填补了 987 车身底部的空缺。车身中部会对车辆产生阻力,而用平板铝板覆盖湍流区域可以显著降低阻力。通过减少后扩散器的湍流,我们能够增强扩散器产生下压力的能力。

它们采用铝板制成,并经过耐用的黑色粉末涂层处理,外观精美,功能正常。搭配我们的后扩散器,可同时降低升力和阻力。

通过 CFD,我们估计车身底部面板可将阻力系数 (cD) 降低 0.007;即 7 个点。

套件包含
• 平坦的车身底部面板
• 支架,987.1(2)
• 支架,987.2(2)

Porsche Rear Bumpers

At Design911, we supply a wide range of rear bumpers for Porsche models, helping you maintain, personalise and enjoy your car.

Why do Porsche Rear Bumpers matter?

Rear bumpers affect how the back of your Porsche looks and how it copes with everyday knocks. Over time they can suffer from impacts, scuffs, UV fading or cracking, or simply start to look tired compared with the rest of the car. Replacing tired or damaged bumpers helps your Porsche feel better cared for and can prevent small niggles turning into larger jobs later on.

  • Keep your Porsche looking smart rather than tired or neglected
  • Help protect the rear bodywork from minor impacts and corrosion
  • Reduce niggles such as misalignment, rattles or mismatched paint
  • Support long-term enjoyment, pride of ownership and potential resale value

Common options & kits

Individual replacement parts 

Specific items to address a particular area or issue without changing everything at once.

  • Ideal for targeted repairs after scratches, dents or cracks
  • Lets you replace only what is needed (skin, carrier, trims, brackets)
  • Helps keep initial repair costs under control

Matched sets or pairs 

Components supplied together so both sides or related items are renewed at the same time.

  • Consistent fit, finish and panel gaps across the rear end
  • Helps avoid uneven wear, colour mismatch or ageing
  • A sensible choice when refreshing the full rear bumper area

Complete kits 

Grouped parts designed to refresh a whole system or area in one go, useful for upgrades and restorations.

  • Everything specified in a single package for a given Porsche model or conversion
  • Saves time compared with sourcing bumper, supports and trims individually
  • Ideal when upgrading to sport, GT or widebody styles, or during restoration

Brands & quality options

At Design911, we stock genuine Porsche parts where available, plus OEM-equivalent and carefully selected aftermarket brands. This lets you choose between keeping things original, adding subtle upgrades or managing budgets on everyday maintenance.

When should you review or replace your Porsche rear bumpers?

Checking rear bumpers regularly helps you spot impact damage, warping or age-related deterioration before it affects appearance, alignment or leads to more expensive body repairs later on.

  • Existing bumpers are scratched, cracked, distorted, poorly repaired or missing trims
  • You notice poor alignment with the rear wings, lights or engine lid after bodywork
  • The car has had a body conversion or widebody kit and the old bumper no longer fits correctly
  • Paint is badly faded, peeling or weathered compared with the rest of the Porsche
  • You want a sportier, GT or OEM-look bumper to improve appearance or originality
  • You are preparing the Porsche for sale and want the rear end to present cleanly

If any of these apply, it is a good time to review your rear bumpers and replace anything that is past its best so your Porsche stays smart, structurally sound and enjoyable to own.
