Not messed with 109 stuff for a very long time.
Presumably the 109 shackles are longer.
How much longer ?
 
Can't see that making any noticeable difference.
Both your axles will be rotated ever so slightly, maybe a degree or two, if that.
At the front it will very slightly alter either the castor or camber angle of the steering (I forget which now 'cos I'm going senile) which theoretically may alter the steering or handling of the vehicle.
I doubt if you'll notice TBH.
Same for the very small alteration in propshaft angles.
