I just ran my car around for the past two days and it seems I have built a perfect racing suspension which is not ver good for the road. At my age I would like an excellent handling road car. The suspension I have does not allow any movement in it and when I do hit the "frozen ice cracks in the asphalt" it does transmit the bump through out the car. I even put about 100# weight in the front to equalize and see if it would cause the suspension to have some movement. Boy, do I have an excellent race suspension.

What do I have????

The front consists of a completely rebuilt/new suspension components including rack and pinion, 21mm after market sway bar, 22mm torsion bars, koni inserts red set on light suspension, etc. The suspension I have just listed causes the front end to move when going over a rough surface and appears to move around on me.

The rear suspension consists of rebuilt/new components including 180# springs on adjustable perches, Koni Red adjustables set to lightest, etc.

The front and rear suspensions are mounted on Elephant Racing Bronze inserts with zert fittings, new hardware bolts, new ball joints, etc.

Where I need comments and information is regarding any possible changes involves the front torsion bars and the rear springs.. Any comments/advice regarding the rest of the suspension that may need changing would be appreciated.

I am thinking of changing the front suspension to 19mm stock originals to lighten the stiffness and possibly give more movement in the front end. The rear would be changed to 140# springs with the rest of the suspension remaining as built. I could possibly go to the 100# springs if deemed necessary.

I need to find out where I can source any parts needed such as the torsion bars and springs. I may have original 911 front stock torsion bars and 914 rear stock springs in my parts bin.

Do you think I should return everything back to original suspension???

Car is powered with 3.2 1987 Carrera Sixer with a "Doc Evil Built and Blessed" 901 transaxle.

Need advice/comments. What do you think????

Thanks,
Steve

The final update on my car suspension will involve changing the springs to 140# without any rear sway bar (hope to keep the adjustable perches in rear) and all the adjustable Koni shocks adjusted to softest setting. The front as mentioned before has been changed to the 18mm torsion bars and 21mm sway bar set on softest setting. The tires will be mounted on the Cup II 17inch rims and will try to step up one or two series (55-60 front; 50-55 rear). Currently running front 205/50-17 and 235/40-17 rear.

I ran the change in the front with the sway bar in rear disconnected and 180# springs. I could live with this suspension with the increase in tire series, but still a little too heavy.

While waiting for the 14# springs to come in, I put on an old set of 80# to 100# set and this did not seem right, maybe a little soft even for my needs.

In sum, I have settled on the 140# springs in the rear without any sway bar. Keeping the 17inch rims with increased size in performance tires probably 55 front and 50 rear. All four corners will have Koni adjustable shocks, maybe adjustable perches in rear.

I have found with the forementioned setup, I can still feel the road and the suspension is working. Remember, the car has been welded and stressed in critical points so that all body flex has been eliminated. The suspension needs to work and I think the suspension mentioned will give me what i want in the car handling. All suspension points have Elephant bronze on all four corners.

I like the 140# springs in the rear.

Now just playing with the suspension adjustments. I can still feed the freeze lines in the road when I hit them dead on with both tires at once, but angling across them gives me a very comfortable crossing. No jars or unexpected movements.

I will not use a sway bar in the rear for normal and spirited road driving. It seems to match up with LSD or locked diff's, not the normal differential. With the rear sway bar detached, the suspension seems to be softer with the 140# springs but is willing to follow the front with minimum sway or related movement.

As "Bugs Bunny use to say, "That's all, folks!""

This thread and the contained information is a great present for my birthday in November.

Thanks for all the inputs and advice,
