About Rear Bumpers

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.
