To get an overall crust without using a CI pan or such can be a touch tricky but once mastered is a talent. First and foremost. High quality steak is required. Second no whimpy thin steaks. I cut my steaks to 1.5" to 2". Anything less go with your CI pan. Next is seasoning. None of this "brining" the meat. Steak needs to be very dry, (wipe down well with towel), light coat of oil (optional). Generous coat of coarse salt (kosher or sea no matter), and pepper to taste. Note because I refuse to use crazy high heat pepper does not burn and cause that bitter taste.
If I am cooking on the Genesis. I get it ripping hot and stabile (stability is important). Then I leave the lid down, turn the middle burner to low (sometimes even off), front and rear burners to medium. While grill is stabilizing with these settings I go back in house and prep my steak(s). (Dry, oil, season). Then right to the grill where they go in the center. Lid goes back down immediately. Let them cook in there a few, then I flip, close lid, cook a bit, flip again. I flip them a lot. Always rotating them as well to make sure no hot/cool spots and crust develops evenly. I pull strips at 125 or so, I pull ribeyes closer to 135. Ribeye is closer to the chuck and has more fat and connective tissue so a slightly more done temp is beneficial IMO. Anyway I get nice steaks every time, no flare ups and plenty of time to enjoy my cocktail while cooking
Also FWIW on that Vette? I'd like red please. Not a silver fan
