The only way to prevent the wheel from tearing out the wheel well liner on full compression (i.e., jumping) is with either a perch collar (which reduces travel, adds pre-load to the springs, like what the Ranger Raptor Race truck used due to class rule limitations that prohibit lifts) or by using strut spacers unless you modify the fender itself (which from a handling standpoint is actually better), but a lift and tires add ground clearance, more so in the front than
Strut spacers from GOAT offroad for example, sit on top of the shock, so you don't lose travel, rather it just spaces the shock down further, because the shock is sitting further down, but still has the same length of travel, it also prevents your tire from going up into the wheel well as far.
Kinda of like an off-set, the entire shock and operating point are just shifted down to accomodate the larger tires by making the shock body longer. You do need a ride height recalibration with Forscan, but anyone can do that with just a laptop and OBDII adapter on level ground.
Lifting the RR, strut spacers are the way to go, if you already have springs to compensate for weight to get the ride height back to stock, then you likely still need spacers unless the springs are specifically designed to lift, but then your back to being heavily under dampened because now you have a much higher spring rate than what the damping rates were tuned for.
That's why if you with springs, ideally, you only want to increase the spring rate enough to get ride height back to stock (minimal amount), then if you want higher than stock ride height for larger tires, you add in strut spacers.
