How low can you go w/o a notch??

Hey I'm new to the mini trucking scene. I've been wanting to build a mini for awhile now. I'm planning on taking over my pops 11' access cab 5 lug or my cousins 14' regular cab also 5 lug. I've been doing a lot of searching of all the different types of ways to lower the truck. I was leaning toward the djm 3/4 kit but not too comfortable notching the rear. So I was wondering how low can you go in the rear w/o a notch? I know the ride will be harsh but just wanna know what my options are? Thanks!

 

3 inch blocks or drop leafs with the bump stop brackets removed is the lowest you can do without a notch...but you will need the qa1s to help keep the axle from hitting the chassis. Any lower and you will require a notch.
