When i bought the car (175,000km) suspension was way soft so i fitted a set of heavy duty Bilstiens... this made a considerable difference but steering too slow and unresponsive..... so i decided it needed a heavier front bar to try to tighten up the steering.....and it still rolls too much... (there's a mob here called K-mac that makes sway bars for everything and if they don't, if you provide the origional bar they will copy it.... for the LS, 3mm bigger which i didn't think was big enough but they assure me 3mm is heaps) .......
i guess i'm trying to create a 'sports' VVTi. We have lots of round-abouts here in Australia, and instead of slowing right down to drive thru one, id like to just 'flick' the car thru..... as it stands, if you attack a round-about too fast, the LS complains and protests so i figure if i put on a 3mm bigger front bar and try to speed the steering up, reduce body roll, and ubove all, just see what difference it makes.....
Yer stiffening the wrong end... put a stiffer rear bar in... Doing the front just makes it plow more. If you want the whole thing to roll less, do both bars, but more in the back than the front....
