Re: Anti-roll bars in a 156 1.9JTD
I'm pretty sure they are the same. There was a thread on here a while back where someone with a 156 GTA was after some Koni FSDs but at the time there was only the one set for the whole 156 range. They brought out the 156 GTA ones later and he contacted Koni, who told him the only differences were to the rear damper units, not the front. Its weird, as you would expect the front dampers to have one part no. for the lighter engines, such as TS, and another part no. for the heavier engines, but they don't. If you specify you have a 2.4 JTD you get sent the exact same dampers as if you specify you have a 1.8 TS. But if you specify 156 GTA the front dampers are the same, the rear dampers are slightly different.
EDIT: Oh, and when I say 'different', I only mean different in operation, not different in fitment. All 156 saloon springs and shocks are interchangable.
