Re: [DML] Upgraded Front Suspension

The fit of the ARB to lower control arm has a lot of room for motion.  Since the 
bar pivots about an axis in front of the control there is room to allow the end 
of the ARB to move in the vertical plane.  The fit is maintained by the 
bushings, which are not steel sleeved like the bushings at the end of the 
control arms.

Thanks Mike..

So, in the Lotus application there was no obvious changes made to allow for the 
arc travel of the ARB?  The movement is absorbed by the ARB itself?  Or did they 
maybe use softer bushings?
