Our customer brought us his 1957 Porsche 356A after it was involved in an unfortunate accident with a tow truck. The car rolled off the tow truck with the driver’s side door open and hit a wall. The door was hyperextended and pushed forward into the front fender.

We have since removed the door and are currently in the process of repairing it. This involves stripping the door of its paint and metal finishing it. Once we have smoothed the door out we will begin the process of repainting the door to its original color. Since the body of the car is essentially all one piece meaning, there are no breaks in the panels; the entire car will have to be repainted.

More pictures to come as we continue our repairs on this beautiful classic Porsche.

We recently upgraded our 1969 Porsche 911S to new H4 SMD headlights from Stoddard. This drastically improves visibility while driving at night not to mention greatly increases safety. As you can see the results speak for themselves!

Product Description: Phosphor Based SMD Headlights For 6V and 12V 356 & 911 Cars. Providing both low and high beam, they produce twice the light of an H4 in a brilliant white light. These are NOT conventional LED's but Phosphor based SMD using the latest technology. They have a working range of 5V to 18V so will work in either 6V or 12V cars. They are not sensitive to changes in voltage as RPM increases and decreases and draw one fifth the current of a regular bulb or H4 halogen lamp! They produce no heat, operate at room temperature and have a working life of 24,000 hours. We include the high quality reflectors as shown with a factory style pigtail so they simply "plug and play". Literally as simple as changing a lamp. No relays needed. Saves your charging system, relays, switches from premature failure due to the high current draw of conventional lighting.

911 Design is currently running an installation special for anyone who is looking to upgrade the headlights in their vintage Porsche. The headlight conversion kit retails for $288.75 plus tax. We will install your new headlights for only $135 this includes adjusting them to properly light your path at night. Give us a call at (909) 982-9111 or stop by the shop to schedule your appointment.
