I don't think that's possibleMust be some kind of sorcery.
I'm not looking forward to that part on my JK.
If you buy a complete suspension system and your Jeep is "typical" for what they designed the system for then the bump stop extensions are usually pretty close but still on the conservative side. IF your Jeep is like ours with pretty much every component altered or changed and a lot of weight added then you pretty much will have to pick a starting point and sneak up on the ideal setup from there. Yes it can be done but it does take some time if you want it exact.
For example, when I first lifted my Jeep back in 2011 I purchased the BDS 4.5" long arm system and it came with 3" bumpstop extensions for the stock D44 housing, that was running 35" tires. I never did hit my fenders or any suspension components in those years.
Now after many more alterations and still around 4.25" of overall lift and 37" tires my final setup is sitting at 2.25" of bump stop in the front and 3.5" in the rear with absolutely no rubbing, but it is quite close. My front actual bump stops measure 3.125" but the Dynatrac ProRock44 housing has a flat spring pocket and they come with a .880" puck to get it to stock height. So I removed that .880" puck and machined one bump stop measuring 3.125" which equates to approx. 2.25" over stock for bump stop extensions. I also have had to trim my front bumper back a little and reform my rear inner fenders but it clears the 37" tires with less bump stop than I did with my 35" tires and the bump stop extensions that came with the kit. I am not willing to get into cutting body or any major surgery to run less bump stop so this is where mine will live. Also worth noting, when I finally gave up on BDS's poly joints and built my own suspension links I put a bit more bend in the front lowers to allow more clearance for when I went to 37's because I would see that tire contacting the lower control arms was a common occurrence.
Just think it through systematically and you will minimize the amount of times you need to mess with the bump stops. Also, if you haven't already seen them, Synergy makes a very nice set of bump stops that snap together in 1" increments allowing you to make changes in 1" increments without having to remove the springs each time. I have used them on a few Jeeps but I ended up machining my own bump stops and I wanted to get it closer than using 1" pucks.
