Eibach Springs for MPS 6 too soft!

[High on PSI]

The Eibach Pro-Kit Lowering springs for the Mazda 6 MPS are way too soft, there's too much body roll when taking corners, TOO MUCH. Will swapping the stock shocks out for Bilstein B8 stiffen things up?

Or will I need different springs do the job?

I know coilovers will do the job but I'm looking at the above options only for now.

Id go Bilstein if it was me, cant go wrong there

You need to ask yourself what you want.
Suspension, like everything about cars, is all about compromise.
If body roll is now your issue, look at sway bars before putting firmer springs in it.
If you put firmer springs in it you will lose ride quality, and you will then also really need better shocks to control the springs action.
The car could end up quite bouncy, and if you drive on roads with bumps, could infact make the car handle worse.

On a 6 I suggest eibach springs, bilstein shocks and a rear sway bar as probably the best compromisefor normal and spirited driving on normal roads.

I know it goes against the craze but unless you track the car, know about adjusting bump and rebound and need to make those adjustments regularly, I don't see the point to adjustable coilovers.

I'll sell you a new Whiteline sway bar...lowered the rear subframe to change the shocks, forgot to make a mark on the headlight leveller before doing so, and cannot be bothered to lower the subframe all over again...

True, try first swaybars.

I was a lot more surprised with the swaybars effect than I was with the coilovers.

With sway bars, are there only rears? or is there front too

[bd581]

There is a front bar, but the OEM one is fine, most benefit comes from changing the rear.

BTW, body roll is not such a bad thing, just feels bad

I know but driving my friends S15, I know they are two very different cars, but it is still on stock suspension and has close to no body roll, while my MPS 6 with supposedly upgraded springs, has lots of body roll. The less the body roll the more comfortable I feel

It's a road car. The more you do to reduce body roll the less safe the car will become on anything other than billiard table smooth surfaces. You risk making the car slower by making it so tight that it bounces off mid-corner bumps rather than staying connected to the road. The most undesirable thing about body roll is its effect on wheel camber, however in modern cars that's not as much of a problem it was back when VW's ran swing arms. The double wishbone arrangement you have at the front is as good as it gets and provides superior control of wheel geometry compared to struts. Getting to know your car better and learning how to get the best from it will no doubt help you to appreciate it more.
