Why flip rear pivot blocks on X-5?

[Fiddybux]

Hi,

I've heard people mention this, and seen setups (e.g. Ellis Stafford), where the rear pivot blocks are flipped over, and out of necessity have been ground away to make room for the outdrives, as the natural left block goes on the right and vice versa. But I wonder what is the point in this? What does it achieve?

I've had a think about it, and as far as I can tell it would raise the chassis in relation to the rear wishbone / suspension arm by about 3mm, or however tall those little lugs are on the pivot blocks are. But what I don't know is what effect this would have on the handling.

Can anyone shed any light on this for me? I'm sure others are wondering the same thing too.

Thanks in advance.
