Just notch it! Even with moving the bump stop to the frame and ditching the bumpstop bracket ur gonna bottom out with a 2" block unless u run QA1's set at an über hard setting. If u don't mind bouncing all over the place then do it, gonna be even worse with 3" and 4" blocks. I just did a notch and I run 2" blocks, can't stand a bouncy ride myself and now I can run the shocks on a softer setting. I also added longer bumpstops to stop my track bar from hitting the charcoal canister.
I also had 2.5" blocks with the bumpstop on the frame but had to run my shocks almost maxed out and still bottomed out too much. It's up to u
