Anyone got a Sway-Bar installed? Care to voice opinions???

[kaanage]

Never heard of K-mac but it's pretty hard to stuff up an anti-roll bar....

They have a VERY poor reputation for adjustable strut tops - never heard anything about their other products.

But yeah, an anti-roll bar is about as simple as things get.

Nah I didn't I told him to contact you if your interested.

Sweet I am interested!

I'm thinking of getting a roll bar but I still have a question. I have AP coilovers on lowest setting on rear, and it is quite a stiff ride because of the light weight at the rear.
The roads I travel to work everyday are at some places extremely uneven (lots of left-side only or right-side only bumps), so if I was to install the rollbar, is the ride still doable or is it going to be comparable to no suspension at all? Because the left and right side will be linked together.. I am willing to give up some more comfort if there's an advantage in installing the rollbar though

Anyone with opinions on this?

[Gambit]

I might be completely wrong but i don't think it impacts comfort when your travelling on a straight piece of road. Its all a matter of personal opinion on what you consider comfort. I'd suggest you get it and install it and see how you feel, if you don't like it, just resell it.

What are you trying to achieve? Is there excessive understeer with the coilovers and you want to balance the handling? Because that is all that a rear anti-roll bar can do (alone).

[Bassik]

I believe the reason Hooti was selling his was because he had his car lowered and it was to much. I can give you reports after I install on weekend and Ill give you a reasonably critical response.

Yeah, ap's on mine were too firm with the other mods.

When the car goes over a speed bump, both wheels move symmetrically, it does nothing.

When you turn, the bar is twisted, reducing lean. When one wheel goes up or down over bad surface, the bar tries to straighten the car, not what you want for comfort.

No easy answer. It affects both cornering performance and comfort.

What the anti-roll bar does give you is the option of using softer springs (and damping) to help return the ride comfort without increasing body roll.

But anti roll bars are essentially "springs"? Stiff anitroll bars will not lead to comfortable overall ride.

[kaanage]

They give twice the roll stiffness vs springs of the same rate since they transfer load across the chassis while a spring will only push up on its side. Otherwise, you wouldn't bother with anti-roll bars and would just up the spring rates.

Plus there is the null rate case over speed humps that noone mentioned (stiff springs are jarring in this case - my B12 kit is a testimony to this).

Coming from a DC2 with Mono Flex's and both sway and strut bars rear and front... the ride after this mod will be so minimal in comparison.

That's why the bleeding edge suspension systems (BMW, Merc, Mclaren) seek to decouple the antiroll bars when not required.
The most annoying symptom of stiff roll bars on factory suspension is the increased lateral head shake feeling when driving down a straight yet uneven road (ie Oz back highways). It's becomes most uncomfortable and fatiguing after awhile.
