Rear extended upper perches. Extended Length.

elephantracing

Fits:
Porsche 911/912/930 1972-89

Coilover springs do not fit into the top of the tapered chassis cavities where the rear shocks mount.
These extended-length upper spring perches solve the problem by moving the spring down where it doesn't contact the chassis.

The perches are available for 2.25″ springs. Or you can add a 2.25″ to 2.5″ adapter to use 2.5″ springs.

They have a 14mm ID to fit Von Shocks, Bilstein RSR, HD, and Sport shocks.

Also available Super Extended Length Upper Perches for '65-'71 cars.

Rear shock tower reinforcement.
Sold per kit, 1 kit required per car.

Fits:
Porsche 911/930 1972-89

✓ Laser Cut – Fits the profile of the shock tower perfectly.
✓ Strong – Solidly ties the towers and cross-member into unibody box sections and inner wheel well. Distributes the shock loads properly and reinforces the entire section.
✓ Holes – Great appearance and convenient routing of hoses and wires.
✓ Weld from one side – Fully seam weld without removing rear firewall.
✓ Light Weight – Properly engineered to distribute loads, not 'over engineered' with excess material and weight.

When converting the 911 torsion bar rear suspension to coilover, the rear shock towers should be reinforced. Coilover springs introduce loads the towers were not designed to handle. Without reinforcement, cracks can develop over time – most frequently between the crossmember and unibody box sections.

Our reinforcement kit strengthens this vulnerable area and properly distributes coilover spring loads.

Rear Shock Tower Reinforcement
Our brackets make it easy to get a professional result, saving you the time and guesswork cutting your own.

This kit requires welding for installation.

Why do Porsche Top mounts Rear matter?

Over time they can suffer from corrosion, wear or cosmetic ageing, or simply start to look tired compared with the rest of the car. Refreshing tired or damaged items helps your Porsche feel better cared for and keeps the overall appearance consistent.

  • Keep your Porsche looking smart rather than tired or neglected
  • Help protect nearby components from dirt, moisture and corrosion where relevant
  • Reduce minor niggles such as mismatched, scuffed or visibly corroded hardware
  • Support long-term enjoyment, pride of ownership and potential resale value
