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.

Fits:
Porsche 911 - 1965 to 1972
✓ 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.

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.
