Classic Porsche Anti-Roll Bars from EB Motorsport

Love these new Porsche 911 anti-roll bars (sway bars) from our friends at EB Motorsport. Sold in matched pairs for front and rear, the front ARB runs through the body, while the rear is suspended across the chassis using the original mounts.

“The EB Motorsport anti-roll bar set has been developed on our own cars in racing,” says EB’s Mark Bates. “Front and rear bars are available in various sizes: 22mm is the most popular size for 3.0 RS and RSRs like our race cars. We use hollow bars as we prefer the characteristics. The ARB stiffness is fully adjustable.

“The EB Motorsport anti-roll bars feature elegantly simple engineering. The bushed mounting system on both front and rear installations is less likely to distort in extreme conditions. Consequently, it resists “grounding out” as many other ARB types are prone to when under high load, such as at the bottom of Paddock Hill, at Brands Hatch.

The original design of this product is multi-piece aluminium, TIG welded. The bushes used by these EB Motorsport Porsche 911 anti-roll bars are a modern polymer equivalent to the original Delrin Acetal resin. Drop links are beautifully machined from aluminium and anodised. Cross drilled moment arms allow for easy adjustment. All connections feature rose joints with machined spacers, to allow free movement.

Some friends of mine use the Smart Racing rear ARB on their classic Porsche 911 for track days, and I have definitely seen those ground out at Paddock. In fact, I have even seen the rear tyre rub against the inside of the wheelarch through that compression zone and burn the paint off the outside of the arch on a 3.2 Carrera. It’s a pretty intense Porsche workout around Brands Hatch! Impressive if EB has found a way around the issue.

The EB Motorsport anti-roll bar kits retail at £1215 ex-works. They are suitable for most early cars, and all 911s up to 1989 with some modification to front fitment: impact bumper 911s are not through-the-body as standard. Contact EB Motorsport via their website to find out more.
