I should add to this, as it has been like 18months since!
Other parts that have gone in/changed:
Whiteline Rear swaybar 18mm
Polyurethane Rear trailing arm bushes
Polyurethane Panhard bushes
Polyurethane Rack mount bushes
190mm 7kg Rear springs
Pros: RIDICULOUS increase in stability, firmer and more predictable body roll.
Cons: Oversteery. Need's 9kg's up front and the rest of the bushes up front changed (have castor rod and LCA's both ready to go in)
