Just measured i need 190mm swaybar link, i know MOT guys might not like cutted and welded link but its 10min job to attach sway bar to factory points for MOT.
im doing this mod

But again i have to criticise these parts, look how much you lose to leverage. you can only get softer with these parts
But for the effectiveness to leverage to bmw it´s about +2mm (18mm bar acts as 20mm bar) but cause 240z sway bar mount is closer to lower ball joint im guessing +1mm for effectiveness
Quick google to 190mm sway bar link says crown vic link might fit, thats not cheap find in Finland

These are easiest. But citroen parts are 5€ each, just need to cut and weld
