Need your thoughts - rear bar Options

[Cracker]

Rear Sway Bar
Need the pros & cons, options and what YOU have actually used. Basically, I have found that there is only the small factory assembly and the Weltmiester system available. I spoke with Ira at Tarret Eng. yesterday but the few prototypes he built years ago are all gone.

Goal
I'm running 315/35/17 rears, a LSD and 300 lbs rear springs. I still have way too much rear body roll than I want. I've tightened up the front sway bar and removed rear camber and that has helped but feel I need a rear bar help beyond that with the body roll out back.

Your thoughts & options?

Have never run a rear bar on any of my personal 914s, but have driven several with rear bar...
Properly setup, I have never felt the need for a rear bar.

WARNING: Personal opinion alert!

I added a rear (stock) bar and it made quite a difference. Not so much in handling, as you can dial in pretty much any type of handling to your personal preference anyways.

What it did do however is that it really helps keeping the rear of the car level and planted during hard cornering.
Many track cars get the same effect by going with very heavy springs and stiff shocks in the rear.

But in my personal opinion, it is beneficial to use a rear bar and be able to run a softer setup on the springs and shocks.
This has allowed me to step down on my rear spring rates from 250lbs to 200lbs yet the car is flatter through the turns and the rear seems to have more "bite" than before.

If I had a car I was driving on the street I might also use a bar and softer springs and shocks. That would help to keep teeth in your mouth. (IMG:style_emoticons/default/smile.gif) Guessing that your car, which weighs more than mine, would require some real heavy springs to keep the rear end flat if you didn't have the help of a bar thrown in.

Bill Pickering always runs rear bars and is quite good at getting the whole "system" to work correctly. It does take lots of adjustment to dial in the setting and you'll find yourself changing settings between morning and afternoon sessions to alter behavior.

You can get good balance either way, but my personal preference is to concentrate on the course instead of trying to dial in behavior.
