Default Re: Aftermarket front sway bar: worth it?

My car came with B6s/oem springs from the previous owner. I liked the handling very much, but i hated sometimes how it reacted on rough surfaces and potholes + i wanted to lower it a bit.
So i got from a friend a used AC Schnitzer suspension (shocks & springs) with ground control street camber plates. Definately much comfier ride but a tad more body roll compared to the B6s.
I was thinking of upgrading just the front to keep the comfort ride of the schnitzer suspension and just to reduce a bit the body roll.

Is it worth it adding just a front? Does it make a big difference over handling/roll/comfort?

I saw EricSMGs post and got me into thinking cause i dont want a firmer ride.

Just don't set the front bar to full stiff if you are street and on stock-ish spring rate. I've ripped out all four studs on my 330i (forgot to change it).

Btw, The rear has two settings, but the soft setting does not seem to have enough clearance, so I ended up setting it to the firmer setting even though I wanted to go soft in the rear and medium in the front. Since I had to set the rear to firm I ended up setting the front to the firmest setting as well and I like the set up that way. Definitely reduces body roll with not noticeable difference in the regular ride comfort, which is already compromised by coil overs and camber plates.

You'll need the adjustable end links for full soft. That's what I'm running with full stiff in the front.

Totally subjective as others have said. I'd say they make manhole covers, etc., about 15% firmer. Not harsh, just a little firmer. And, it's probably less noticeable the more your car is modified. However, if you feel like the car is just barely within your comfort limits as-is this may push it over the edge.

That said, IF the amount of body roll you have now is bugging you then a front sway is the perfect mod for you. I wouldn't even question it.

Thank you for the input Eric.
I might try just the front (H&R).

Are the Turner Motorsport Custom Length Adjustable Front Sway Bar End Links necessary or stock are OK?

IMO, adjustable endlinks are only necessary in two scenarios:

1. When you're corner balancing and want absolutely zero pre-load between L and R.

2. Super low ride heights where you need to return the sway bar to it's "stock" position at static right height. This is desired since the leverage on the bar is reduced proportionate to the bar's tilt from parallel... if that makes sense.

For all other cases I'd say they're a cool, but totally unnecessary, mod. I tend to avoid adding additional adjustments and/or moving parts unless it solves a problem. New OE links are like $18 each and last a long, long time.

I don't understand why less body roll ("cornering flatter") is considered an upgrade

Mid corner do you want more or less negative camber on your outside wheel? Overall, do you prefer a car with solid axles or independent suspension?

Unless you're running out of travel, I don't see flatter as better... and if you are, there's probably other places you should be looking to address that.

Totally agreed, but I didn't want to go there. I've never had any interest in eliminating roll - it certainly doesn't hold the car back.

Then CSL sway bars just because?
I've been thinking about a Hotchkis front-only setup (hollow/lighter bar, 11% stiffer than stock). Not sure yet.

I have the CSL sway because it's lighter, silent, and I prefer that setups' oversteer/understeer balance.

This is worth repeating. Keep an eye on the sway mounts when tracking with a big front bar on soft springs. Or better yet, change the springs first.
