Welcome to the Team Brian!
You car is already sitting about one and a half to two inches lower now than when it left the factory from just the springs sagging with age.
If you are not going over board on wheel and tire size then a dropped spindle is your best bet. I have used a dropped spindle with new stock ride height springs on seven by fifteen inch police wheels (the ones with a bunch of round holes in them instead of the five slots as used with a Rally wheel) running 235R60-15 Goodyear Eagle II's with the tire hitting the frame in back of the axle only on hard turns.
I mention wheel width because with a dropped spindle the wheel is no longer centered on the steering knuckle so if you have an eight inch or wider wheel up front it could contact the tie rod end at end at the steering arm.
Why a dropped spindle is better than lowering springs (or cutting your stock springs) is that you retain all of your suspension travel and it doesn't adversely affect your steering geometry. With dropped springs you loose two inches of shock absorber travel requiring revalving the shocks to keep the suspension from hitting the suspension bumpers. Those suspension bumpers have to remain even though they are now two inches closer because if metal hits metal parts break such as pulling a ball joint off the A-arm.
You can buy modified plastic suspension bumpers and new shocks designed to work with the reduced suspension travel but such changes will affect ride quality. Though if you have been riding a hard tail bike I suppose anything would be an improvement.
