My rear uprights are off and I was thinking of removing just the rear spacers from the springs for now. I have no alignment problems, but my question is, will this create problems by removing them? Also, will it look funny leaving the front spacers in? I have stock 8" in the rear, and 7" campy's in the front. My searches on this were rather vague. I saw "last push buttons" photos concerning this and I'm further motivated to do it, while waiting for my forged axles to be delivered. Thanks. I'm going for that lowered look.

Yes it will change the rear wheel camber by removing the rear spacers and lowering the car. However I don't think it will start wearing out your tires or noticably affect handling in the short term.
I do think it may look funny to just do the rear.
Fronts are not much harder to do, I would do both at same time.

Have the car realigned after both front and back have been done.
