Customize Your Porsche® Interior


Add a Designer Touch

Choose from a wide variety of colors and patterns to add a designer touch to your interior. Select a fabric that incorporates the accent colors of your exterior, seat belts, deviated stitching, and/or brake calipers. We are happy to consult with you to find the perfect color combination. Consider us your "Automotive Interior Designers".

Insert Covers and Foam for a full TURN-KEY Solution

Unlike our competitors, we offer a complete turn-key solution that includes both covers and custom foam, P1Custom Foam.  Our foam is sculpted to fit the contours of the original seat, made of automotive foam that is very similar in density and feel of the original.  Simply remove your originals and install your new custom seat inserts.

Comfort - Integrated Lumbar Support Option

We offer an inflatable lumbar support that is integrated into the seatback. The lumbar bladder is placed between the fabric and foam, and you can adjust the amount of support to meet your specific comfort level. Pictures of this option are included in the "Customer Photos" section.

Comfort - Memory Foam Option

We offer a memory foam option incorporated into the seat pan and backrest inserts for increased comfort over the OEM foam. If you are looking for a way to enhance the comfort of your seats, this is the option for you. The increased comfort is especially noticeable for people with lower back discomfort or who drive long distances in the LWB seats. Without the memory foam, our inserts feel very similar to your original LWB seats.


Our material is automotive fabric, which is tested to ensure durability  100,000 hour UV tested - Scuff Test approved - Scotchgard® protected


We specialize in custom! We are not a high volume shop - all projects are made to order. Contact us to discuss using any type of material or fabric pattern you choose to customize your seat inserts.

Integrated Lumbar Support

"I challenged the P1Designs team to not only build me seat inserts for my Porsche GT3RS, but to do so with an integrated inflatable lumbar support.  Kim was fabulous to work with as we collaborated on how to execute on the lumbar support."

"The result was sensational!  Not only do I have beautifully crafted seat inserts that fit perfectly, but P1Designs stealthily addressed what is arguably the biggest ergonomic shortcoming of Porsche's LWB seats - they can cause lower back pain."

"I couldn't be happier with the outcome and highly recommend P1Designs."

Comfort Foam Option

"I had Kim custom make me the Pepita inserts with the additional memory foam to keep my wife happy on longer trips. Just did a drive from Central California to Los Angeles, about 4 hours and the improvement was significant! My right leg used to get numb after 2 hours of driving with the LWBS, but I was pretty comfy and didn't have the usual numbness. The memory foam also did a better job of contouring to my lumbar area for the backrest. "

"BTW, Kim and her husband are an absolute pleasure to deal with! Very responsive to all my requests and always thinking about ways to improve based on my feedback. Not to mention the quality of their product is top notch! I'd say they are on par if not better than the factory inserts."

Tartan - Black/Grey/Yellow with Memory Foam

Memory Foam Option

"I would just like to let you know how pleased I am with your product and your personal service.  Your memory foam has got to be the best "option" for a GT3!  It totally transformed the feel of the seat.  The tartan fabric also matches the yellow seat belts perfectly.  Now I can have full bucket seats that are as good to look at as they are to sit on."

I have had my seat inserts from P1Designs for more than a year.  Great people to deal with and honest. The price is best for the quality and service, They are great for track use. I am in Texas and it gets hot and with these insets you notice a big difference because the inserts breathe better.
