Well I've been running polyflex LCA rear bush, OEM (20mm) front ARB with 28mm rear neuspeed ARB set on mid point for three years with only one mad tail out event, which was a bit of fun. I think this set up coupled with my S3 strutt brace balanced out the stiffness of the rear a bit. I do feel the rear is a bit too stiff but am in the process of fitting a R32 23mm ARB with new wish bone bushes and hope this will be a perfect set up. Hopefully at the SCN national meet we can all get spins in cars with different set ups to see what feels and handles the best
