50mm is what is legal before engineering so it's not advertised, best guy to speak to about OA is Peter Myrdycz 0498 328 013 , Peter is a suspension design engineer , he setup mine 3" with custom rear springs
if your also adding larger diameter wheels i wouldn,t go any higher in the lift than 50mm, also having this 50mm lift is not as harsh on the cv,s etc as opposed to a higher lift.
