Sway Bar options

[e30trooper]

Im running a vert front sway on poly bushings and 25 year old stock rear. My car sux :(

So the shape of the sways makes a big difference.

yes, the shape of the bar changes the length of the "spring" which determines it's stiffness.

I think I'm going this route after all that haha.

IX 14.5mm
Cabrio 22mm

Is there a good bushing/endlink kit? for this size?

New stock bushings and end links will work fine.

You can find new heavy duty rubber bushings, I don't remember
where I saw them.

Source the parts for the car you took the bars off of for correct sizing.

the endlinks are the same on all E30s. the bushings will be from an ix or M3.

If money is the problem, Use the rear bar from an IX (19mm) and the front bar from a cabrio (22mm)

I run these on my 318i, Replace the stock bushings with something harder, and run new end links. Decent street setup.

OOPS, IX bar= 14.5mm, Brainfart.

the ix/m3 rear bar is 14.5mm, not 19mm. but, it'll still be a cheap upgrade over the 318is's 12.5mm bar.

Cabrio front sway bar is 21mm

......And the shape of the bar can dictate the length of the endlink. And subsequently the endlink length dictates the bars articulation (the shorter the endlinks, the less articulation the bar has, resulting in the bar going over-center much easier).
