Yes the ke70 roof is about two inches or so higher so it needs to be modified to be worthy of engineering.
Besides, It would be pointless to not sort out this problem as it would sit lower than your head if not modified
I'm sorta tall tho so could be me...
Also I'm pretty sure a full cage fits in a ke70, ask beally (driftke70) pretty sure he has a full safety 21 cage
