Sway bar Options

[JMe30]

I have completed my s50 swap into my e30 87 without the sway bar. Can you advise on the best aftermarket option available or how to install the factory bar with ideal clearance?

Will be using as a daily driver.

Thanks

any bar that fits with an m20 should fit with an m50.

Yes, But what setup will provide the best clearance for the headers down pipe.

generally the subframe is more limiting than the sway bars you use.
I think ST bars are lowest, hanging lower than the subframe IIRC, but I would not compromise that for exhaust clearance, any exhaust shop can make an exhaust that will clear both your subframe and sway bars, whatever they may be, stock or not
