lowering the dart?

I'm going with Magnumforce Racing's 2" drop spindles up front. They are the best bang for the buck I found but watch out on the shipping charges. I hated to do it but for now I am going with Mancini Racing's 2" drop blocks in the rear. They are a good kit and it comes with hardware. Eventually I would like to go with a stiffer rear spring but one that lowers the car instead of the blocks.
