Manufactured from aerospace-grade titanium, the front
anti-roll bar offers exceptional strength with considerably less weight than a
conventional steel anti-roll bar. The reduction in unsprung mass allows the
suspension to react more efficiently, delivering improved steering precision,
flatter cornering and greater driver confidence on the road, track or rally
stage.
Whether you're building a lightweight restomod, historic rally car, fast road Porsche or dedicated competition machine, this Tuthill anti-roll bar kit is engineered to maximise the capability of the legendary air-cooled 911 chassis.
Kit Contents
• 1 x titanium front anti-roll bar
• 2 x front anti-roll bar lever arms
• 2 x front anti-roll bar bushes
The titanium anti-roll bar measures 19mm and delivers a stiffness rating equivalent to a solid 15mm bar, offering enhanced front-end stability and reduced body roll while maintaining lightweight performance characteristics.
To further optimise weight and rigidity, the anti-roll bar lever arms have been completely redesigned and precision-manufactured from lightweight aluminium using topological optimisation techniques. This engineering approach maximises strength while significantly reducing component mass.
Compared to standard steel components, this kit provides a substantial reduction in suspension weight, improving steering response, chassis balance, suspension efficiency, and overall handling dynamics.
Ideal for enthusiasts seeking lightweight motorsport-inspired suspension upgrades for classic Porsche 911 builds.
Key Features
• Lightweight titanium front anti-roll bar kit
• Designed for Porsche 911 long wheel base models up to 1989
• Aerospace-grade titanium anti-roll bar construction
• 19mm titanium anti-roll bar
• Equivalent stiffness rating to a solid 15mm bar
• Lightweight aluminium anti-roll bar lever arms
• Topologically optimised lever arm design for reduced weight and increased
rigidity
• Significant reduction in suspension component weight
• Improves chassis balance and front-end response
• Suitable for road, fast road, and track applications
Lightweight Suspension Performance Benefits
Reducing suspension and chassis weight improves overall handling precision and suspension response.
Weight Comparison – Anti-Roll Bar
• Steel Anti-Roll Bar: 1.43kg
• Titanium Anti-Roll Bar: 0.52kg
Weight Comparison – Lever Arms
• Steel Lever Arms: 4.4kg
• Aluminium Lever Arms: 1.8kg
Benefits include:
• Reduced unsprung and rotational mass
• Improved steering response
• Sharper turn-in characteristics
• Better chassis balance
• Enhanced suspension efficiency
The result is a more responsive and agile Porsche driving experience.
Aerospace-Grade Titanium Engineering
The anti-roll bar is manufactured from aerospace-grade titanium for the ideal combination of lightweight performance, structural rigidity, and durability.
Titanium offers:
• Exceptional strength-to-weight ratio
• High resistance to corrosion
• Reduced suspension mass
• Long-term durability under load
• Motorsport-grade reliability
Perfect for lightweight builds, fast road applications, and track-focused Porsche projects.
Advanced Aluminium Lever Arm Design
The included aluminium anti-roll bar lever arms are topologically optimised to remove unnecessary material while maintaining maximum structural integrity.
This advanced engineering process provides:
• Reduced overall component weight
• Increased stiffness and rigidity
• Improved suspension precision
• Greater durability under performance use
Why Upgrade to a Titanium Anti-Roll Bar?
Factory steel anti-roll bars and lever arms are heavier and less optimised for modern performance driving.
This upgrade provides:
• Reduced front suspension weight
• Improved body control and handling balance
• Faster steering response
• Motorsport-inspired chassis performance
• Lightweight suspension engineering
