TORSION BAR SET, PORSCHE 911, 20 mm RATE
TORSION BAR SET – PORSCHE 911, 20mm RATE
SKU 1820T
Category: Porsche Torsion Bars
A precision-engineered front suspension upgrade for the air-cooled Porsche 911. These 20mm torsion bars offer a targeted increase in spring rate over the standard factory bars, providing crisper turn-in and reduced body roll. The "T" designation typically indicates compatibility or sizing specific to the torsion-tube configuration of certain performance models, making this the ideal "Street-Sport" upgrade for owners who want a more planted feel without the harshness of a full-track setup.
Performance & Fitment
Application: Front Torsion Bar Set Diameter: 20mm (Performance Upgrade) Spring Rate: Stiffer than OEM (restores and enhances front-end geometry)
Porsche 911: 1965 through 1989
Porsche 912: 1965 through 1969
Porsche 930 (Turbo): 1975 through 1989
Note: Specifically chosen for those looking to sharpen front-end response or for vehicles being prepared for "Fast Road" or Autocross use.
Premium Construction
Material: Solid 4340 aircraft-grade alloy steel, chosen for its exceptional "torsional memory" and fatigue resistance.
Manufacturing: Centerless ground to a precise 20mm to ensure a perfectly linear spring rate and remove surface micro-imperfections that can lead to stress cracks.
Heat Treatment: Through-hardened and shot-peened to ensure the car maintains its corner-balanced ride height without the sagging common in aged factory components.
Finish: Industrial-grade powder coating for superior protection against moisture and debris.
⚠️ Installation & Performance Notes
Balanced Handling: When upgrading the front bars to 20mm, it is highly recommended to also upgrade the rear torsion bars to maintain the 911’s neutral handling balance. Pairing 20mm front bars with 26mm or 27mm rear bars is a common "sport" configuration.
Indexing: These bars utilize the factory splined ends. Correct indexing (clocking) during installation is critical to achieving the proper stance. Document your original bar's orientation before removal to simplify the setup of your new ride height.
Maintenance: Thoroughly clean the female splines in the A-arms and adjustment caps. Apply a high-quality waterproof grease to the splines during assembly to prevent future seizing and "creaking" during cornering.
