The original owner of my IM Roadster, wanted to auto cross it, so he installed some killer sway bars front and back (IRS). These are formed bars that attach directly to the front and rear swing arms.

They make a bit of noise when going over bumps, and they make the suspension stiff as a cast iron bed.  I have no intention of racing this car. These will be removed and made available to anyone that may wish to use them on their car.  They appear to be in perfect shape and I will not know their brand, until I remove them, if there is a logo on them???

It's amazing how much front and rear sway bars can affect a car's handling.

On my track Miata both front and rear bars had three settings.  During a day at the track I could dial in more understeer or oversteer just by switching the settings (holes at the end of the bar).

I wonder how your car will handle with no rear bar?  Even with just a stock front bar it might be a handful.

I ran my IRS pan with just a front 19mm (3/4") sway bar (Sway-Away) for several years.  It handled pretty well with (I thought) minimal body lean in hard cornering.  Back then, I had 205X16 tires front and 225X16 in the rear with 1-1/4" wheel spacers on a flared car. 

 

Then I added a 19mm sway-away bar to the rear.  After that, it REALLY handled flat and felt much more "positive" in really hard cornering and I have never gotten the rear to break loose - believe me, I've tried, but I ran out of cojones before those big rear tires would ever let go (this was on the track, not the street).  Watching from behind with Chris driving, it sits very flat all through the corner and might be fun if I knew how to make it "drift" (!!)

 

On the downside, both bars make everything pretty stiff and you feel every crack in the pavement.  Not so bad with just the front one for street vibrations, but if I wanted an ice cream/weekend cruiser, I would opt for just a front and something smaller, like 3/8" - 1/2", just to soften the ride a bit.

With thicker sway bars and a rear 'kafer' bar my IM's ride is on the stiff side, but I like it that way.  It gives the car a real 'solid' feel. 

My IM feels as stiff as my street/track Miata, which had a number of chassis re-enforcements, Koni 'race' shocks, and seriously thick springs, along with some very thick sway bars.

If I was aiming for a 'cruiser' type of ride I go with Koni shocks (fronts set to soft and rears set to 1/2 hard), a stock sway bar, and skinny 65 or 70 series tires.

A set of cheap, oil-filled shocks (not gas) would also work and be considerably cheaper.

I agree about a smaller "stock" bar on the front.  My car IS really just a cruiser, smile and wave, kind of ride. I confess at having a 911 too, that has aggressive suspension and ride height, when I get 'the need for speed'...

The current setup is, as stated, very stiff and a bit noisy over bumps and such. I'm sure it would be the Bee's Knees for another's car….just not for me.

Bill…when I have it off, I will let you know.

As per usual, you all rock……..
