New page

The Anti-Roll Bar or '''ARB''' is an integral part of your car's [[Suspension|suspension]]. Its function is to reduce body roll by locking together all the suspension components across each axle. By stiffening the entire system in this way, it's possible to dramatically reduce the wallowing, lurching motion that is often encountered otherwise.
__TOC__
=Overview=

The ARB itself mounts to the car body using two rubber [[Bushes|bushes]], held in place with steel shells. The two ends of the ARB then mount to the wishbones via '''drop links'''. These drop links operate similarly to [[Suspension#Ball_Joint|ball joints]], allowing for lateral movement in the suspension without compromising stiffness, but are actually another type of bush and need to be replaced with the same regularity.

A number of sizes of ARB were fitted to the E30, and upgrades were available from a number of manufacturers including [[AC_Schnitzer|AC Schnitzer]] and [[Racing_Dynamics|Racing Dynamics]]. The thicker the ARB, the stiffer the suspension. See the tables below to see what was fitted to your vehicle.

=Standard=

BMW offered an impressive range of ARBs, designed to combat the suspension niggles specific to each [[Bodywork|body style]] and and [[Engines|engine]]. While Front anti-roll bars were a standard feature, not every car received a rear ARB.

'''WARNING''': This list is NOT comprehensive! We have not yet ascertained whether all [[Touring]]s and [[Cabriolet]]s had the same suspension. If you are unsure as to the size of your ARB, try to fit a spanner onto the bar itself. For example, if you can fit a 14mm but not a 13mm spanner around your rear ARB, then it is 13.5mm.

=Aftermarket=

While BMW offered an impressive range of ARBs for the E30, many were simply not beefy enough for true performance driving. Because of this, a number of tuners offered much stronger versions as bolt-on upgrades.
