Homemade Porsche Parts Are the Best For My Wallet

Anytime improved grip and/or upgraded suspension hits the track, that means the chassis and driver take some additional bumps, loads, and stresses too. So, stronger Anti-Roll Bar mounts and larger diameter bars are common upgrades on early air-cooled Porsche 911s to reduce corner roll. To clarify, some folks call them sway bars too, but those in the know prefer not to call them that. Sway bar implies that the bar adds sway which we don’t want!

Wider and modern tires also increase grip which tends to increase chassis roll in the corners. As a result, more roll means more stress on the anti roll bar mounts (ARB) mounts. Since Porsches don’t have a heavy frame system this means that the factory sheet metal mounts sometime fail or tear. As a result, stronger anti-roll bar mounts are needed for sure as shown in the Porsche pictures below.

Front ARB Mounts

Some aftermarket solutions exist to improve these areas, but I decided to save cost and build my own strengthening plates for my car. For example, sheet metal armor plates provide stronger anti-roll bar mounts for the front of my Porsche. These simple plates match up to the bulkhead sheet metal behind the inner fenders. Oddly enough, they kind of look like the Porsche crest don’t they?

A simple flat plate would not be perpendicular to the through the body sway bar that I intent to run. My Solution was to make two plates to match both angles correctly. I installed a temporary bar to aid in the alignment of my new plates.

Here’s a link to video showing the whole process!

Rear ARB Mounts

Luckily my stock rear mounts look good (not torn!), so I decided to box them in with additional sheet metal. Similarly, I welded extra long nuts to each bracket to prevent the nuts from pulling out under severe driving conditions. Nothing in the car is stronger than the rear torsion bar tube, so I elected to extend my stiffening brackets up to the torsion tube for good measure.

This video shows how I incorporated the rear stiffening plates to my stock ARB mounts

Porsche 911 Chassis Strengthening Mods

This video shows some of the strengthening plates that I didn’t have access to when I added the rear coil-over chassis gussets. To learn more,Click here for that project post.

I’m really happy with all the chassis mods that this car sports proudly!
