rear sway bar eibach

Hi,

I just installed the eibach sway bar front and rear..
after install the rear was bumpy af, itll just bounce on the rear for whatever on the road.. even on acceleration itll jump.

the front is ok, but I had to swap to oem on the rear..
any fix to this issue?

You didn't install it upside right? If so the rear bar would sit on the rear control arms and cause the bumpy feeling i.e. no suspension travel.

I thought it was only a one way.
Do you have any pics of the correct install?

Waiting for Koni special active shocks in december, after that install I will put the sway bar back and test.

Unfortunately I learned the hard way the bar can install both ways, when I did it upside down I had exact symptoms as you.

No pic but the bend where the bar turns outside the bushing, it should "loop" around the rear control arm. If it is upside down, the bend will face down and sit on the control arm.

Thanks for your feedback, will reply in 3 months when parts arrives..
I've read in a few post that for some folks the ride is too harsh, but this is outrageous..

The ride from bars that are too stiff is harsh but not bouncy, and the REAR bars are not too stiff. It's the 30mm fronts that generate all the "too stiff" comments (including from myself).

It was almost certainly installed incorrectly as other posters have stated. I've been running the H&R 20mm rear bar (same thing, just blue) for years and wouldn't want to be without it.

Same. Just running the rear no aftermarket front. It does feel stiff when going fast over a pothole or something.

If the car is on stock suspension, it will be a bouncy ride with after market sway bars. I have tried several combinations of suspension setup. Best balance of comfort/sport is Msport sway bars & after market coilovers.
