sway bar help
 

What is the advantage/disenvantage to put a heavier swaybar in the back of my 1979 1303 vert. Is a 18 mm example overkill for a convertible that is heavier a a "normal" super? At the front i'm driving a 23 mm bar from Kerscher. ;)

Kerscher sell a 16mm bar to compliment the 23mm front bar, The same shape and material bar with a diameter of 18mm may very well be superior for a vert. But they may have too much torsional rigidity for a regular super? I don't know.

Different design rear ARB's cannot be compared by diameter alone, very important.
