The Complete Guide to 356 Porsche Recaro Seat Parts

Installing Recaro seats in a Porsche 356 is a popular upgrade for enthusiasts who want better support and comfort without sacrificing the classic character. Whether you’re restoring a 356A, 356B, or 356C, choosing the right Recaro seat parts is essential for a proper fit. This guide covers the key components you’ll need, compatibility considerations, and practical installation advice.

Understanding Recaro Seat Models for the 356

Recaro has produced several seat models that are commonly fitted into vintage Porsches. The most popular choices for the 356 include the Recaro Sport Seat (often called the “Ideal” or “LS”) and the Recaro Classic LX. These seats offer a period-correct look while providing modern lumbar support and bolstering.

Recaro Sport Seat (Ideal/LS)

• Style: Low-back, slim profile reminiscent of the original 356 seats.
• Fitment: Requires custom brackets for the 356 floorpan.
• Parts needed: Seat itself, mounting brackets, sliders, and hardware.

Recaro Classic LX

• Style: Slightly taller back with integrated headrest, more modern shape.
• Fitment: Also requires custom brackets, but some aftermarket kits are available.
• Parts needed: Same as above, plus possibly a seat belt guide loop.

Essential 356 Porsche Recaro Seat Parts

To install Recaro seats in a 356, you will need these components:

1. Mounting Brackets

The 356 floorpan is unique, with angled mounting points and limited space. Generic Recaro brackets won’t work. You’ll need brackets specifically designed for the 356. These are often sold by Porsche restoration specialists or fabricated by custom shops. Look for brackets that:

• Match the bolt pattern of the Recaro seat (usually 10-inch or 12-inch width).
• Provide the correct seat height and tilt angle.
• Allow enough clearance for the transmission tunnel and door sill.

2. Seat Sliders

Recaro seats come with sliders, but they may not fit the 356’s narrow floorpan. You can use Recaro’s OEM sliders with adapter plates, or buy sliders that are pre-drilled for the 356. Ensure the sliders are low-profile to maintain headroom.

3. Hardware Kits

Bolt kits are often overlooked. You’ll need high-strength metric bolts, washers, and lock nuts. The original 356 seat bolts are M8x1.25 pitch. Recaro seats typically use M8 or M10 bolts. A hardware kit that includes both ends saves frustration.

4. Seat Belt Mounts

If you’re switching from the original seats, you may need to relocate the seat belt receptacles or use lap belts. Some Recaro seats have built-in belt guides. For shoulder belts, consider a harness bar or roll bar mount.

5. Spacers and Shims

Due to the 356’s uneven floor, spacers may be necessary to level the seat. Plastic or aluminum shims can be placed under the bracket.

Compatibility and Installation Tips

Floorpan Differences

The 356A (pre-1959) has a slightly different floorpan than the 356B/C. Always measure your mounting points before ordering parts. Some brackets are labeled “356A” or “356BC” – verify fitment.

Seat Height

The 356 has limited headroom, especially with a helmet. Recaro seats sit lower than original due to their thinner cushion, but brackets that raise the seat too much can cause your head to touch the roof. Aim for a seat position that keeps the seat bottom about 1-2 inches from the floor.

Tunnel Clearance

The transmission tunnel is narrow. Most Recaro seats fit without issues, but the seat adjuster lever on the inboard side may rub. You can modify the lever or use a remote release.

Door Clearance

With a thick Recaro seat, the door may not close fully if the seat is positioned too far outboard. Test fit before final installation.

Where to Find Recaro Seat Parts for a 356

While we avoid specific marketplaces, you can source these parts from:

• Specialist Porsche restoration shops – They often stock or can fabricate brackets.
• Recaro authorized dealers – They can order sliders and hardware.
• Custom metal fabricators – They can make one-off brackets if needed.
• Vintage Porsche forums and clubs – Members often have leads on hard-to-find parts.

When buying used parts, check for rust or damage. New brackets are preferred for safety.

Step-by-Step Installation Overview

1. Remove original seats and carpet for access.
2. Test fit the Recaro seat with a temporary bracket to assess height and tilt.
3. Mark and drill holes for the bracket if needed. The 356 floor has dimples that indicate original hole positions.
4. Install seat sliders onto the Recaro seat.
5. Bolt the brackets to the floor using the hardware kit. Use thread locker.
6. Attach the seat/slider assembly to the brackets.
7. Adjust seat position and tighten all bolts.
8. Reinstall seat belts and test for function.

Pro tip: Use a seat riser template from a restoration supplier to simplify drilling.

Final Recommendation

For most 356 owners, the best approach is to buy a complete mounting kit from a reputable Porsche parts vendor. These kits include brackets, sliders, and hardware designed for your specific year. Avoid mixing and matching universal parts unless you have fabrication experience. A proper installation not only enhances comfort but also ensures safety in a vintage car that lacks modern crumple zones. If you’re unsure about drilling into your 356’s floor, consult a professional restorer. The investment in correct Recaro seat parts pays off every time you drive your Porsche.
