Porsche's Carrera RS and RSR models, the RennSport develops the original
concept with a taller backrest, increased lateral support, Duralastic seat
support and redesigned hinges to make it more practical for everyday road use
and longer journeys.
Supplied as a frame kit ready for upholstery, it allows you

local interior specialist.

Carrera RS / RSR-Inspired Design
The lightweight sports seats fitted to the Carrera RS and
competition-focused RSR became an important part of Porsche's
motorsport-inspired interior design.
The original seats prioritised low weight and driver
support, with period versions using Nylon/Perlon flame-retardant fabric as part
of their lightweight construction.
The Retro Trim RennSport takes inspiration from these
classic seats while introducing several changes aimed at improving support,
comfort and everyday usability.
The seat has been developed with:
- A
taller seat back
- Increased
lateral support
- Duralastic
seat support belts
- Side
adjustment
- Redesigned
seat hinges
- Waist
belt openings incorporated into the frame
- Rosettes
for 5-point harness openings
The result is an RS/RSR-inspired seat with additional
support and practicality for classic Porsche road cars, restorations and
restomods.
The seat frames also incorporate waist belt openings and are
supplied with rosettes for 5-point harness applications, providing additional
flexibility when building a more motorsport-focused interior.
Any seatbelt or harness installation should use the correct
vehicle mounting points and be installed appropriately for the intended
application.
Lightweight Construction
The RennSport is designed around the lightweight principles
of the classic Porsche RS and RSR seats.
The lightweight frame reduces unnecessary seat mass while
providing the structural foundation required for the foam, support system and
upholstery.
This makes the RennSport particularly suited to lightweight
Porsche builds where reducing vehicle weight is important without sacrificing
everyday seating comfort.
Fire-Resistant Foam & Duralastic Support
Fire-resistant foam is combined with Duralastic belts within
the seat structure.
Rather than relying entirely on thick foam for support, the
Duralastic system helps support the occupant while allowing a degree of
controlled movement.
This creates a seating position that feels supportive and
firm without making the seat unnecessarily harsh for longer journeys.
Improved Side Support
Compared with the classic seat that inspired it, the
RennSport has been developed with additional lateral support.
The increased side support helps hold the driver more
securely in position during cornering, reducing the amount of movement across
the seat during spirited driving.
This makes the seat particularly attractive for classic
Porsche owners who enjoy fast-road driving but still require a seat suitable
for regular road use.
Redesigned Hinges for Everyday Use
The seat hinges have been redesigned to improve durability
and make the RennSport more suitable for regular use.
This is particularly important for road-driven classic cars
where seats may need to provide comfort and practicality on longer journeys as
well as support during more enthusiastic driving.
Have Your Seats Upholstered Locally
Purchasing the RennSport as a seat frame kit gives you
complete freedom over the finished appearance.
The kit can be supplied directly to your preferred local
upholsterer or restoration specialist, allowing the seats to be trimmed
alongside the rest of the vehicle's interior.
You can choose:
- Leather
- Vinyl
Fabric
- Perlon-inspired
materials
- Period-style
Porsche upholstery
- Bespoke
restomod finishes
- Contrasting
or matching stitching
- Materials
matched to existing door cards and interior trim
This makes it possible to create anything from a
period-inspired Carrera RS/RSR interior to a completely bespoke classic Porsche
restomod.
