Rear 22mm Anti Roll Bar & Adjustable Drop Links Kit.

Fits:
Porsche 911 1978-89

The light-weight hollow sway bars are half the weight of a 22mm solid bar with the same stiffness. They are fabricated from aircraft-quality 4130 chrome moly alloy steel and heat treated to maximize strength and reliability. Bearing blocks, drop links, and swaybar arms are CNC machined from aircraft-quality 6061-T6 aluminum for its high strength/weight ratio. Fully adjustable front and rear drop links to eliminate suspension preload. Correctly sized, precision, Teflon-lined rod-ends for smooth and quiet operation, long life, and high reliability. No wear and rattling problems, like those seen with other designs, due to undersized or low quality rod ends. All necessary hardware is provided in zinc plated metric class 8.8 The adjustable drop-link arm connection design provides an infinitely adjustable swaybar stiffness rate and makes it quick and easy to fine-tune your car's handling for various track conditions and driving styles. Thermoplastic bushings impregnated with Teflon and reinforced with Kevlar provide smooth operation, long life, and high resistance to deflecting under heavy loading. Superior ground clearance. Compair the competition. Optimized geometry for bind free operation throughout the entire suspension range of travel. All components are designed and manufactured to the highest quality standards, resulting in the finest and most reliable swaybar on the market.

Rear retro RSR adjustable sway bar.

Fits
Porsche 911 - 1965 to 1989
Porsche 911 turbo - 1977 to 1989
Porsche 912 - 1966 to 1976
Porsche 914 - 1970 to 1976

Retro RSR Adjustable Sway Bar System

Retro appearance combined with modern performance and features make these adjustable sway bars (anti roll bar) a great choice for period-correct builds.

Drop links

Appearance similar to the RSR originals with a grey colour for a discreet and retro appearance. Left and right threaded precision rod ends make easy work of adjusting front drop link length. Adjustable length makes it easy to eliminate any preload on the bar. Teflon lined rod ends never require lubrication.

Lightweight

Hollow bars weigh half as much as similar solid bars delivering equal stiffness..
Bushings

Teflon impregnated bushings are grease and maintenance free and provide smooth operation and long life.

Through-body style front bar

Installs through the body same as the pre-1974 cars and the early turbo cars. Cars not originally equipped with a through-body sway bar should purchase the optional backer plate kit.

Retro-Look Arms

Steel arms are similar to the original RSR type and have drilled adjustment positions.

Titanium Rear Anti-Roll Bar Kit 

Upgrade the rear suspension performance of your classic Porsche 911 with this lightweight Titanium Rear Anti-Roll Bar Kit, engineered specifically for long wheel base Porsche 911 models up to 1989.

Manufactured from aerospace-grade titanium, this advanced rear anti-roll bar system is designed to reduce weight, improve chassis balance, and enhance rear-end stability during spirited road driving and motorsport use.

Fits:

• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50
• Porsche 911 1975-1977 3.0L Turbo (930)
• Porsche 911 1978-1989 3.3L Turbo (930)

Kit Contents
• 1 x titanium rear anti-roll bar
• 2 x rear anti-roll bar lever arms
• 2 x rear anti-roll bar bushes
• 2 x rear anti-roll bar mounting brackets
• 2 x rear anti-roll bar drop-links

The titanium rear anti-roll bar measures 22mm and delivers a stiffness rating equivalent to a solid 18mm bar, providing improved body control and sharper handling characteristics while maintaining lightweight performance benefits.

To further optimise suspension efficiency, the anti-roll bar lever arms have been completely redesigned and precision-manufactured from lightweight aluminium using topological optimisation techniques. This process maximises rigidity and strength while significantly reducing overall component weight.

Compared to factory steel suspension components, this kit delivers substantial reductions in unsprung and rotational mass, improving suspension response, steering precision, and overall chassis dynamics.

Ideal for lightweight restorations, fast road builds, and track-focused Porsche 911 projects.
