After throwing my back out for a fifth time while doing back squats, my doctor told me I should switch to front squats because it helps maintain a more upright position. I'm 6'4" and he said that with the back squat tall people can put a lot of pressure on their low back if they lean too far forward and lead with there butt. Apparently this is what I've been doing so I'm switching to a front squat.

My concern is that I have overly strong quads compared to my hamstrings as it is. My understanding is that front squats focus more on quad strength than a back squat. If I include deadlifts, hamstring curls, and KB swings into my leg day is this going to be enough to compensate for the more quad focused front squat? I'm trying to balance my hips out and I don't want the switch to be counter productive.

Thanks.
