why not get coilovers, with the correct measurements you will know where to mount them in a custom location for proper suspension travel and as long as it's not to low you won't have to notch the frame, it's easy and JEGS has lots of options that work/worked well, they have even brakets that can be bolted up from the coilover to the frame or you can weld it, It made sense for me to get something I knew would ride like a dream, let the car sit where I want with the travel I want without the restrictions of hoping stock suspension doesn't bottom out or hit the frame, and you will have easy adjustable ride height with the coilovers.
