Adjustable 19mm Front Anti Roll Bar Kit.
Upgrade the front roll control of your classic Porsche 911 with this adjustable 19 mm front anti-roll bar kit. Designed for 1965-73 911 models, this kit replaces the standard 15 mm bar with a stiffer 19 mm unit, and includes adjustable levers/drop-links to fine-tune roll stiffness. Whether you’re restoring a vintage 911 or upgrading for performance, this kit offers improved cornering stability, sharper front-end response and tuning flexibility.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

What This Product Does:

• An anti-roll bar (sway bar) connects the left and right sides of the front suspension to resist body roll during cornering. It transfers load between the two sides so the outside wheel shares part of the load with the inside one, reducing lean.
• By increasing the diameter from 15 mm to 19 mm, the bar becomes stiffer, thus reducing body roll further and improving cornering stability and front-end responsiveness.
  
• The “adjustable” aspect of the kit allows the driver or technician to change the lever arm length or link pivot point to vary roll stiffness—so you can fine-tune how much the bar contributes vs the springs.
  
• This kind of upgrade improves chassis balance, driver feedback, quicker turn-in, and reduced dynamic body lean — especially beneficial on vintage sports cars like the 911 when driven spiritedly or on track.

Symptoms & Signs You Might Need This:

• You feel excessive body roll at the front during cornering, or the front end feels soft or unstable in lateral transitions.
  
• The handling is less sharp than you expect, especially if the suspension has been upgraded (lowered, stiffer springs) and the standard sway bar is now the weak link.
  
• You’ve installed wider or stickier tyres, or uprated front suspension components, and want the front anti-roll bar to match the rest of the setup.
• You want to tune or adjust the balance between understeer/oversteer – using an adjustable bar lets you adapt front roll stiffness.
• You’re restoring a vintage 911 and want a strong, performance-capable bar with correct style and function.

Why Replacement / Upgrade Matters:

• A stock sway bar may become inadequate when other suspension elements get upgraded — lowering, heavier wheels, larger tyres all increase demands on the bar. Upgrading to the 19 mm adjustable kit ensures the front links are not the limiting factor.
• Improved roll stiffness means the car behaves more consistently under load — less lean, more predictable weight transfer, better driver confidence.
• The adjustable kit gives you tuning flexibility — you can adapt the stiffness for road vs track, or change the balance if you alter tyres, springs, or other suspension components.
  
• In a vintage car, a properly specified upgrade also helps maintain or enhance value — strong handling and correct appearance matter.
• Finally, a performance upgrade like this supports safer driving dynamics when pushing the car harder.

Adjustable 22mm Front Anti Roll Bar Kit.
Upgrade the front roll control of your classic Porsche 911 with this high-performance adjustable 22 mm front anti-roll bar kit. Specifically designed for 1965-73 911 models, this kit replaces the original 15 mm bar with a larger diameter 22 mm unit and includes adjustable drop-links/levers for fine-tuning roll stiffness. Whether you’re restoring a vintage 911, upgrading for spirited driving or prepping for track use, this kit enhances cornering stability, improves front-end responsiveness and allows tuning to match your suspension setup.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

What This Product Does:

• The front anti-roll bar connects the left and right front suspension arms, limiting body roll by transferring load from the outside wheel to the inside wheel during cornering.
• A larger diameter bar (22 mm vs 15 mm) increases torsional stiffness, reducing body lean, improving turn-in and chassis stability.
• The “adjustable” aspect adds the ability to change the lever arm or drop-link position, allowing fine-tuning of roll stiffness (e.g., softer for street, stiffer for track) without changing the bar itself.
• As a result you get sharper front-end response, flatter corners, improved tyre contact and more confidence in dynamic driving.

Symptoms & Signs You Might Need This Upgrade:

• Excessive body roll or lean in the front end during cornering, or a feeling that the car “leans” more than it used to.
  
• The front suspension feels less sharp, turn-in feels delayed or vague — especially if you’ve already upgraded springs, shocks or tyres and the bar is now the limiting factor.
• If your car has been lowered, fitted with wider tyres, stiffer suspension, or is used for track, the factory bar may no longer provide adequate control.
• You want to tune or adjust your front roll stiffness — the adjustable kit gives you that capability.
  
• Visible signs: a thinner or corroded stock front bar, worn drop-links, excessive movement in the front roll bar mount bushes etc.

Why This Upgrade Matters:

• By increasing front anti-roll stiffness, you improve the car’s dynamic behaviour: better balance, less front body-roll, sharper front-end response, and improved driver confidence.
• The adjustable feature gives real world flexibility: you can match stiffness to your tyres, springs, driving style or track/road use rather than being locked into factory spec.
• For a classic 911 used in sporty driving, cautious track use or performance upgrades, this bar upgrade supports the rest of the suspension system rather than being the weak link.
• If you leave the stock bar while upgrading other components, you risk handling being compromised — upgrading ensures all parts rise together.
• Finally, from a restoration perspective, fitting a well-specified upgrade enhances the value and usability of the car.

Adjustable 24mm Front Anti Roll Bar Kit.
Upgrade your classic Porsche 911’s front suspension with this premium 24 mm adjustable front anti-roll bar kit, designed for 1965-1973 911 models. Replacing the original ~15 mm bar, this kit includes the thicker torsion bar, adjustable levers/drop-links and full mounting hardware, offering significant improvement in chassis control and tuning flexibility. Ideal for restoration, spirited road use or track preparation—this kit gives sharper turn-in, less body lean and the ability to fine-tune roll stiffness to match your tyres and springs.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

What This Product Does:

• The front anti-roll bar (sway bar) connects the left and right front suspension arms, limiting body roll by providing a torsional link between the two sides when cornering.
• By upgrading from the stock ~15 mm diameter bar to 24 mm, you significantly increase torsional stiffness of the bar—thus reducing body lean, improving turn-in and helping the chassis resist roll under load.
  
• The adjustable feature means you can change the effective leverage or drop-link mounting position (shorter vs longer arm), thereby tuning the roll stiffness to match springs, tyres, driving style or track vs road use.
  
• For a classic 911 with upgraded suspension, wider tyres or lowered ride height, this kit helps ensure the anti-roll bar isn’t the weak link and supports sharper front-end handling.

Symptoms & Signs You Might Need It:

• The front end of your 911 feels soft or “floaty” in corners, or there’s noticeable body roll—especially compared to performance cars of similar vintage.
  
• You’ve upgraded the suspension (lowered springs, stiffer dampers, wider tyres) and the original anti-roll bar seems to “give” too much or let the car lean more than you’d expect.
• The drop-links or bar mountings show excessive wear, movement or noise (clunks) when turning or going over undulations.
• You want tuning capability for ride/handling balance—stock fixed bars don’t allow easy adjustment of roll stiffness or corner-balance differences.
  
• Visual inspection reveals the stock bar is thin, corroded, the mount bushes collapsed, or the drop-link geometry is showing signs of age.

Why This Upgrade Matters:

• Improves chassis precision: With a thicker bar and adjustable feature you gain better front-end response, sharper turn-in, and less understeer due to roll-control improvement.
• Works with the rest of your suspension: If you have upgraded springs/tyres/dampers, this bar ensures those upgrades aren’t compromised by a weak sway bar.
• Tuning advantage: Because the kit is adjustable, you can dial in the front roll stiffness to match your use (road vs track) or alter the handling balance (understeer/oversteer) more easily.
• Classic 911 value: For older cars, having performance-capable and maintenance-fresh suspension components adds to usability and resale value.
• Longevity: Stock bars and mountings from the 1960s/70s may be corroded or tired—replacing with a modern, thicker and adjustable kit improves durability and driving confidence.
