I am sure someone out there is good with the maths of comparing anti roll bars/sway bars. Can you please help?
Currently I run a 20mm solid bar. This is too soft (professional race drivers assessment as well as mine) and I have no way of adjusting it, so it is to be discarded (put on the shelf!) and a replacement fitted.
I have a choice of two tubes in front of me right now. Both are 25mm (1 inch) outside diameter but the wall thicknesses vary. The skinnier one has a wall thickness of 2.6mm and the chunkier one has a wall thickness of 6.25mm. I can't seem to find a wall thickness tube of 4mm (or thereabouts) as a halfway house.
The effective lenght of all three bars is 27 inches, 685mm. The leverage lenght is the same for all bars.
Clearly both the skinny and chunkier tubes will be stiffer than the 20mm solid bar but by how much? In addition how much stiffer is a 25mm solid bar over a 20mm solid bar?
For discussion sake assume all materials are the same grade steel, CDS2.
Can anyone help, please? Thanks.
