Sway bar size questions

[HotRod]

Interested to find out what size of the front and rear E30 Sway bar/anti roll bar

AC Schnitzer -- mm?
Eibach --mm?
RD --mm?

TQ.

Eibach: front 20mm rear 16mm
Racing Dynamics (adjustable): front 22mm rear 19mm
AC Schnitzer: front 20mm rear 16mm
Suspension Techniques: front 22mm rear 19mm
H&R (adjustable): front 22mm rear 18mm

I might be missing a couple of companies though.

All sizes are for non M cars.

Don't forget, Ireland Engineering! 22mm rear, 25mm front :shock:

Cabrio Front- 21mm
M3 Rear- 14.5mm

These are cheaper than aftermarket companies.

even better, 19mm front and 14.5 rear, too much on the front causes heavy understeer, which is what i was experiencing with the 21mm front arb and 14.5 on the rear, swapped round to the 19mm and it really made a difference, the car rolled alot more but it didn’t understeer, so its up to you and what you want the car too do. Remember less body roll means less drifting, but its best to correct this with harder spring than ARBS, but then the ride quality is gone, so its a compromise really.

stock front is 19mm, no?

[demlotcrew]

im pretty sure its 20mm stock, could be wrong long time since ive worked with them.

i think the front M3 bar is 19mm and the 6cyls have 20mm; however, i'm not sure about the compatibility of a M3 front bar on the front of a non-M e30 due to the different pickup points

[aaron_silva]

The M3 bar mounts up to the non-m pick-ups.

[Rob]

using non-M end links I would presume

[aaron_silva]

correct.

So whats the stock size sway bars for the front/rear of a 325i,325iS, 318i, and 318iS?

[Rob]

318is, 325is: 20mm/12mm F/R
m10 318i: dunno about the front, but no rear


someone correct me if i'm wrong

[chesster6969]

Im assuming the sways for regular i models are the same for iS models?

Cabrio Front- 21mm
M3 Rear- 14.5mm
