Adjustable F/R sway bar availability?

[shawn908]

Read many posts via search for "sway" in the tech forum. Looking for sway bars as in title for my car. It's a street car, but I'm slowly evolving it to a AX capable street car. So quick question: just two manufacturers (JWE and Tarett) of adjustable sway bars to consider for 911, right?

Those two are really the best anti-roll bars on the market today. You can't go wrong with either brand.

[Driven97]

I think the Elephant bladed ones are put together by them, and Weltmeister ones are a more budget option. A few companies resell the Tarret ones.

Also keep an eye on the classifieds. There are some good products by companies no longer in business.

Look into Rennline's annual X-Mas discount sale, it's 15% off and they carry the full Tarett line, that's where i got mine from !

Another consideration is customer support / service. Tarret, JWE and Elephant are all excellent.

Thanks for tip on X-mas sale wildcat077 - good to know as also considering a battery downsize and relo. It's an evolution and if I get these sway bars in the next month - budget shot until December (or until I can hide parts acquisition, whichever comes first).
Agree, Driven97 - I've searched the classifieds but nothing out there, at least now.
Will get a shop to install. Threads indicate not a trivial j o b.
Thx for feedback.

I won a couple of championships with the Weltmeister sway bars. They're really easy to adjust. I liked them.

Compared to the Tarett and JWE anti-roll bars, the Weltmeister anti-roll bars are junk. You couldn't pay me to use Weltmeister anti-roll bars. I'd rather run Racer's Group crap!

Here's the car last weekend showing some roll. And it was under steering (badly) on sharp U-turn. Suspension is Bilstein shocks HD/Sport F/R and torsion bars 22/29 F/R. There is no rear sway on the car. Front sway yes. Car is '74 w/3.2 (stock). It's a blast to drive but feels unsettled and my driving skills need work, too.

An otherwise '74 with a 3.2 is completely unbalanced. Time to step back, consult a shop that knows how to properly balance and set up your car and then go forward. And yes, learn how to drive... but not in a twitchy car.

[shawn908]

Agree, and the car was lowered and corner balanced last year when the suspension was refreshed (by a shop that knows these cars). I'll be working with them on the ARBs as well, starting today.

I have swapped a lot of bars in and out. It is frustrating to be doing a track day and find you are out of adjustment on a front or rear bar and have to settle for more under/oversteer than you want.

Since you already have the suspension rebuilt, I would suggest you talk to one of the three mentioned to get the bars sized properly from the beginning. Talk to them about what you have done to the car and what you "think" you might want to do to the car.

If you haven't beefed up your rear bar mounts, you may want to do this in conjunction with a rear bar upgrade. The Wevos worked very well for me. The Carrera 18 mm rear bar had torn off when my dad had the car - going to a 20 or 22 rear bar would probably tear the bar mounts off before you even got the bar on the car - just sitting in the driveway - seen it happen :-)

sorry, too many coffee beans...

[Driven97]

98% sure you are on the bumpstops in those photos. Car is really low, and 22/29 are pretty soft torsions.

When you are on the bumpstops your spring rate goes through the roof, and the car will definitely feel unsettled.

[shawn908]

So I've been delayed on ordering the adjustable roll bars (work, life etc). Have managed to run two more AX. I ran this weekend with same setup (torsion 22/29 F/R with HD/sport bilsteins F/R). Based on reading/info I'm considering to order JWE with #27 front bar and #23 rear bar. Just curious what others' experience might be considering below photo from most recent AX. I'm wondering if 29 TB in rear is enough for this car?

Go as big as possible on the torsion bars, especially the rear.

110% chance that you're sitting on the right rear bumpstop in that photo. That would leave your tire as the only suspension you've got going on.

Also willing to bet you bang the front bumpstops on corner entry based on how low the car is.

For comparison, here's my car on 36mm rear torsions, which are 240% stiffer than 29s:


Disregard the fact that I don't have enough rear camber in this photo.

I'll fathom a guess that your car is pushy on initial turn in to slow corners, really pushy on sweepers at steady state throttle, but real snappy and tail happy in slaloms and hard transitions. Am I warm?

[Driven97]

Also of note, that inside front is pretty high up there. Do you happen to have aftermarket poly front swaybar bushings? Was there a bump on the course there?

[RichardNew]

When I was running SCCA Solo 2 I would have someone watch the car for lifting. the car worked best when the inside front was about 2-inches off the ground.

After some discussion I would change the sway bar settings before the next run.

Driven97 - yeah, more than warm, hot. That's what I'm experiencing. Makes it a challenge on slaloms to control rear from trying to get in front and I'm not enjoying the tight turns and push. The R888s hold well considering. Could be better. You think 33mm in rear would do the job? Thinking about street ride too. The 29s are far from too stiff - I would be fine if firmer (for how I like the car to drive). So I can go higher. I'm realizing that there is a component of testing that is required: not every car is the same. Thanks for any additional input.
