Sway bars

[Kdog2112]

Anyone have any aftermarket sway bars so I dont have to spend 500 on the ones from Racing Dynamic off of Bavarian Autosport?

Suspension techniques, or used M5 bars

For an E34, you can order the whole set of M5 bars with new bushings and the works for under $300, I believe. You can get a Euro M5 25mm/19mm set like I have, or I think there is a N'Ring, or Touring package of 25mm/20mm, too, if it can be found.

What do these feel like? Are they really only for racing, or can you feel the difference in handling with normal spirited daily driving?

Here's the review I wrote for bimmer.info:


I bought an MTech set from Cacatfish, 25/19 I believe. Current config:

Totally stock suspension (187k, probably not all original, soft but not totally worn-out)
Bruno's rear subframe inserts
15" baskeweaves - 225/60 rear, 215/60 front (PO's fault)

The swaybars made a noticeable difference in body motions during those quick transitions you mentioned. Swerving to miss a pothole-type of motions, correcting for a little power oversteer, those kinds of things. Overall the car rolls less, gives the feeling of faster turn in (less time spent 'taking a set'). I would also say that the overall cornering limit is higher, significantly, even. I would not say at this point that I have less understeer, which was a surprise to me. Mid-corner or even towards corner exit I can put more power down due to the higher limits, but it is actually less likely to oversteer than it was before.

Obviously my staggered tires will add understeer, but I'm speaking in a relative standpoint comparing my current setup to the stock swaybars with the same tires/suspension.

My theory is that overall cornering grip has gone up due to better body control and reduced lateral weight transfer, but the 25/19 combo and the staggered tire factor mean that I still get some understeer, and it's a bit more noticable now due to the higher limits.

Overall the car just feels better, smaller, lighter, and more willing to scoot through a corner rather than wade through it. Make sense? But it did not totally make the car neutral.... the RD bars probably do a better job of that. I'm happy with my purchase...it's a street car and the price was right. I really hope to put a Sach's kit on sometime in the near future and see what that will feel like. Between that and some wheels/tires, this could be a really, really good handling car. :D Well, for weighing 3700 pounds, anyway.

BTW, I don't, nor will I ever race the car...it's just a street car. A rather noticably more fun street car now, though. :)
