Each mirror set is supplied complete with mirror glass, providing everything required for installation.

Please Note:

• Sold as a pair (one pair required per vehicle)
• True bolt-on installation using factory mounting points
• No drilling or door modifications required
• Mirror glass included

Why Upgrade to Rennline Cup Style Mirrors?

Whether you're building a GT3 Cup-inspired road car, preparing your Porsche for track days or simply looking for a more purposeful exterior, Rennline Cup Mirrors provide one of the most distinctive styling upgrades available.

Benefits include:

• Authentic GT3 Cup race car styling
• Lightweight, compact mirror housings
• Cleaner, more aggressive exterior appearance
• Direct bolt-on installation
• No permanent vehicle modifications
• Premium carbon fibre or paintable
• ABS construction
• Ideal for both road and track-focused builds

What Do Door Mirrors Do?

Door mirrors provide essential rearward visibility, helping the driver safely monitor surrounding traffic when changing lanes, overtaking and manoeuvring the vehicle. They also play an important role in the overall styling and aerodynamic profile of the car.

The Rennline Cup Mirrors retain excellent rearward visibility while replacing the bulky factory mirrors with a more compact, motorsport-inspired design.

Why Do Door Mirrors Need Replacing?

Original mirrors can become damaged or worn over time through:

• Parking knocks
• Road impacts
• Cracked or broken mirror housings
• Damaged mirror glass
• UV fading and weathering
• Failed electric adjustment mechanisms

Many owners also upgrade purely to achieve the iconic Porsche Cup car appearance.

When Should They Be Replaced?

Replacement or upgrading is recommended if:

• The mirror housing has been damaged
• Mirror glass is cracked or broken
• Electric adjustment mechanisms have failed
• The original mirrors are faded or worn
• You're building a GT3-inspired road or track car
• You want a lightweight, race-inspired appearance without modifying the vehicle

This ordering flows more naturally by introducing the design inspiration, then immediately explaining why Rennline's mirrors are different, before moving into the available options and benefits. It also places the installation advantages much earlier, which is often one of the biggest selling points for customers comparing Cup mirror conversions.
