Wow, beautiful bodywork. It is so hard to make black look good, and this really does look good!
If it was me I would lower the front 1/2 inch or so - there are kits available from Denis Welch and others. Basically shims/spacers you place between the spring pans and the a-arms to lower the spring pans & therefore the ride height. If you do lower the spring pans you should raise the rubber bump stops the same ammount. Since the spring pans are about 1/2 way out the length of the a-arms, however much you lower the pans, the ride height will go down about twice as much - 1/4" spacers = approx 1/2" drop in ride height. Good part is no modifications to the car and it's totally reversable.
Just remember there are some negatives. Ground clearance is already marginal and will be worse. Also, lowering the front will make it even harder to see over the top when using the rear view mirror with the top down.
