Chassis Tuning - Whiteline Anti-Roll Bars
Whiteline Logo Changing springs and dampers is just one aspect of improving a car’s ride and handling. There are other aspects of chassis tuning which will improve a car’s ability to corner, thus making the handling more sure footed and ultimately improve a car’s overall performance and feel.
Manufacturer’s generally set up their front wheel drive cars to be very predictable and inherently ‘safe’ for the everyday driver, as opposed to the enthusiast, with the usual trait being that of understeer, where a car will run wider through a corner and wash out to the outside of the track or road. A slight correction to the throttle brings the nose back in and restores grip levels. Clearly this is not the quickest way through a corner and whilst improved springs and dampers will help other items should be considered as well.

Springs and dampers are designed to control the vertical movement of the car rather than roll, so to improve the handling uprating anti-roll bars will take the strain away from the springs and dampers and help a car corner flatter, with less roll, and make the tyres work harder and grip better. With the roll taken away from the springs and dampers and being controlled by a bar they are left to do what they were designed for, controlling the car over the road surface.

Front wheel drive cars feature a front anti-roll bar to help control body roll, but with performance and suspension improvements faster cornering is possible and therefore a thicker bar is required to combat the extra body roll and further improve cornering ability.

Most front wheel drive cars however, are not fitted with rear anti-roll bars as they will alter the Manufacturers’ understeer characteristics of the car, however looking at altering these components will give vast improvements in a car’s handling and cornering ability without detracting from its ride comfort. Fitting a rear anti-roll bar will reduce body roll and make the rear tyres work harder offering higher levels of grip.
Whiteline Automotive, an Australian company has its roots in the original Shelbys Steering and Suspension company, started making anti-roll bars in the 1960’s for road and race cars. With products engineered via the race track for road use, their components are designed to help cars corner faster and flatter.
Whiteline Logo
Their range of products have been engineered and manufactured to the highest standards from excellent quality materials,  the aim being to provide performance handling solutions where function is always more important than form.
We have tested a range of Whiteline’s products including the front and rear adjustable anti-roll bars, front caster adjustment kit, adjustable front anti-roll bar link arms, and rear camber and toe-in adjustment kit on our own Astra 2.2 SRi and Astra VXR's and the rear anti-roll bar on Vectra B running a coilover suspension. We found them to be of excellent quality and give amazing results improving handling, road holding and transforming the cars' abilities.

For anyone wanting to seriously improve the handling of their car we would suggest the addition of a rear anti-roll bar where available.
