That said, I'm ok with a little more understeer - my wagon has been oversteering a bit ever since I installed the 20mm rear sway bar (OEM sedan bar), so a slight increase in understeer would be ok by me.
Trouble is, I really think I'll rub if I lower the back, but there's plenty of room to drop the front.
When you lower the front of the car, the whole car is tilting forward. More weight over the front end. Balancing the front to the rear by adding stiffer springs is putting a bandaid on the problem.
Also note: When attacking bumps, the stiffer front will feel harsh while the soft rear may bounce. Roll stiffness in the rear will be increased by the rear sways, but a sway bar is no substitute for stiffer springs. The front will act much stiffer, and I wouldn't be surprised if you had a fairly large increase in understeer. Which would you rather have? Understeer or Oversteer? Exactly.
I doub't you'll rub by dropping less than 1". The tire will tuck underneath the fender as the suspension arcs through it's travel.
