    Vert/M3 swaybar question.

    I'm looking to keep my car balanced but would like a little flatter cornering. Current setup: '91 318i sedan, H&R sport springs for a 325i (xxxx6) Billy sports, E90 drop hats, No rear pads to loose the rake. 16x8 w/ not overly sticky tires. stock sways F&R. Used as a Daily driver

    What I'm thinking of doing: Vert front 21mm and M3 14.5 rear bars. M3 offset bushings- should do this soon because PO put the stockers in wrong.
    My big question is about the sway bars- anyone with that combo? do you think it would still be balanced?
    Right now it is pretty well balanced but it will push slightly at the limit, I'd just like a little less lean.
    You say "Where are your other two cylinders?"
    I say "Where's your other camshaft?"
    Frankenmotor: if an M42, M44, M20, S50, and S52 were to have a kid.

    If you want flatter cornering, ditch the H&R sports. I have the 21mm front and no rear sway and love it. The back end never steps out anymore.

      I like the ride quality of the H&R sports - I went with the 6cyl springs so they'd be a good compromise between 'race' and stock. If I just ad the 21mm ft bar, my well-balanced car will push like a Honda FWD

        What is the advantage of running no sway in the rear. I just dont understand why it would be there if it is not needed?

          I have H&R sports, Billie Sports, Vert/M3 sway bar combo. On the street it's great. On the track there is still a lot of lean, which is from the H&R sports. It has slight oversteer, but I don't have the stickiest tires for the track.

            No rear bar will equal more understeer.

            The stiffer you make one end, the more weight transfer will occour at that end. (this is a gross assumption but it works well as a basic rule). by removing the rear bar you will soften the rear end forcing the front end (which is already overloaded) to take more weight transfer which could/will give you more push. This in turn will give you more understeer. You'll find this more typically on autocross cars (and the opposite [big rear bar, little front] on drift cars).

            For street it just depends on one's personal preference, though some prefer the driver feed-back you get with more understeer (kind of makes you 'feel' quicker turning into an on-ramp).

            Hope that helps.
