M3 anti roll bar on 325?

[Two_Sheds]

I noticed an M3 rear ARB for sale on ebay, just wondering if it would fit my '87 325, and if it would be a worthy upgrade. The car is a track car, primarily for drifting, its lowered 60mm all round with adjustable Avo dampers at the back, so its hardly roly poly at the moment anyway, but the ARB is so cheap I'm just wondering whether it might be worth a punt to gain a bit extra!

I think theyre about 1mm thicker

aint the touring rear arb the same as the m3 as well

According to real oem the rear ARB on a standard m3 is 14.5mm, which is the same as a 325i sport, and only 1mm thicker than the standard 13.5mm rear ARB on a 325i.

However a 1mm increase in diameter will increase the cross sectional strength by over 15% (16.5mm squared as opposed to 14.3 mm squared)

Does it attach in the same place ? (wider track)

Yes, the M3 roll bar will straight swop, fit's in the same place as any other E30.

The front anti-roll bar mounts different on an M3, but I believe you can still use normal E30 drop links to mount to the wishbones.

Touring with leveling device has the same bar I belive
