Sway bars, are they worth it?

Legato2057 · 01-19-2012, 05:11 AM

I have a 2008 335i sedan lowered on Koni FSD and Eibach pro springs. I am considering getting a sway bar kit (maybe eibach or hotchkis). I don't do many track runs - hopefully this summer tho. Is it really with it? Does it make enough of a difference to justify the $500?

Personally, I wouldn't get it regardless of the price especially if you're not going to track the car. It's one thing to stiffen up the ride quality but if you're going to keep stiffening the suspension (springs,struts, sway bar, etc), it might reduce your sense of your loss of traction if it were to ever happen. I'll try to find the source for this bit of info but hopefully it helped.

Warning: Stock rear sway's so thin that it may be hard to find. Try M3 sways and while you're in there, R&R the rear subframe bushings w/M3 parts. Install a LSD. Name: DevilSmiley.gif

Your life is greatly improved w/flat cornering; a suddenly very cohesive rear with all your ponies getting power to the ground.

Sex is better. Food tastes great! Careful: Your smile may blind oncoming traffic....

I wouldn't. No LSD=leave sway bars alone..

Legato2057 · 01-19-2012, 02:48 PM

Thanks for the help. I was planning on getting an LSD soon, so I think the best plan is to wait until after that at least. I want to make sure that when I start upgrading the horsepower that it transfers to the pavement efficiently. After LSD is COBB AP and FMIC!

I would more likely to get rear sway first.

Front is not that necessary. BTW, LSD is a great upgrade, I will do it when I get my money.

Front<Strut<Rear<LSD

Unless you have an LSD as noted, don't do the rear sway. You will be worse off in turns. The inside wheel gets nearly all of the power in a tight turn because of that open differential; a thicker rear sway will actually lessen the grip and you'll have even less 'push' going through.

FYI rear sway = drop the subframe, which is very expensive. Do it at the same time as LSD + subframe brushings.

Translation: BMW e-diff gonna eat the soles offa yo shoes.

A macabre device programmed for your vexation, rear brake shoes disappear long before fronts, all the while providing inferior performance and feel.

The engineers responsible for that should be outed and forced to view every minute of every Oprah every day.

Take the cure! Wavetrac or Quaife for street duty, and you may thank GOD for that!
