What diameter ARB? Track
 

What size ARB do you recommend, i was think 24mm front and rear, both adjustable, but Whiteline also do 27mm and seeing as i'm planning on making my car a track weapon, i was thinking about these, but are they really needed, would 24mm all around be fine?
Where does the diameter stop mattering, is there a maximum diameter before a thicker diameter would no longer be benificial?

Thanks
