Blades are adjusted by pulling on spring loaded detent pin, simultaneously rotating the blade (by hand) into another hole in a locating tab then releasing the detent pin to lock in the new position.


When the blade is in the fully stiff position, rotating the blade to the fully soft position reduces the linear rate of the bar by approx. 40%. This wide range of adjustment is incredibly useful to set up the overall roll stiffness of the car to suit the spring rate, tyres and driver preference as well as balancing the relative front-to-rear  stiffness for grip balance (typically over/understeer).


At the “non-blade” end, the drop link can mount in 3 bolt on positions to give additional adjustment in the same style as a normal ARB.


The ARB is a direct bolt on replacement for the standard bar and comes complete with all of the fasteners, mounting blocks and (rod end) drop links needed.


Cornering Force ARBs are designed in-house by a Race Engineer to suit the additional roll stiffness requirements of track use with stiffer springs/dampers.


Single or Double Blade ARB?

Single and double blade ARBs will have the same fully stiff rate. The double blade bar will give a wider range of adjustment that will provide greater set-up options for a more demanding user, for example a full wet set-up.


A Rear ARB?

If no rear ARB is used then all of the rear roll stiffness comes from the springs. In terms of vehicle dynamics principles this is not ideal and there is benefit from using a suitably rated rear ARB. We have designed a range of Lotus rear ARBs to fully compliment our range of front ARBs.
