Would appreciate any advice/comments on my squat form @ 92.5kg
Thanks
Brace your core properly (imagine you're squeezing out the biggest battler ever), slower and don't drop so low.
Your lean is probably caused by going too low, which is causing your core bracing to screw up (as your hips tuck under) because you aren't controlling the squat properly.

Drop the weight down by around 20kg and try some squats there so we can see what goes on at lower weights...
