Thought you guys might enjoy these pics Supposedly this is a turbo cup front sway bar but it is identical to the 968 M030 bar. I have a 21mm rear adjustable sway that is also supposed to be factory turbo cup equipment and is a little bigger than the 968 19mm rear M030 sway bar.

Sooo....how much?

Well - I am thinking if I could glue all the parts to the floor - cut it out and frame it around $1200? Perfect for an executive office!

Hmm, should all swaybars have those E-Clips to keep the outer bushing on?

SWEET!

I used regular hose clamps on each sides of both end bushings. I think when you go with that fat bar(M030) you need something to retain it. I never put on the E clips when I bought my bar from Andial years ago ... It seemed like you had to scratch the bar to put them on so when the bar slipped out of the end bushing, I used the hose clamps ... It never came out again
I just plated a lot of stuff and all that hardware was done as well
Looks very clean

The 968 M030 front bar is the same part as the 87+ Turbo Cup bar, same factory part number. So, yes - identical.

The Cup rear bars are the 21mm 3-way adjustable bar. The adjustable ends are noticeably beefier than the 19mm 968 bar. They are also noticeably stiffer than the 19mm bar. When still available, up to about 12 years ago, they were over $500 from Porsche motorsport.



The factory c-clips are only intended and available for the 30mm bar.

I have seen bars pop out of the drop links on track cars, but usually there were some other problems, worn out bushings, something bent, etc.

If you want to step it up a notch, I have the following parts available for the Turbo cup bars;

Racers Edge - Delrin bushings front
Diagonal strut support for front frame drop mount
Racers Edge - Red anodized aluminum bar mounts for the rear bar
Racers Edge - spherical drop links for the rear bar

Are the rear mounts compatible with the 21mm bar? I know the fat ends on the 21mm bar did not fit through Karl's rear bar mounts, but I don't know if he has revised the design (in the past few years) so newer mounts now fit the bigger bar?

Beautiful front sway bar set up. Like you said, it looks exactly like the 968 M030 parts I put on my 951.

Good observation. The stock mounts took quite some effort to clamp down over the 19mm rear bar and bushings from the 968 M030 and fit very snugly. Probably wouldn't have worked if the bar had been 21mm.

Thanks Jim for the background on the turbo cup sways - very interesting to know.

Had a buddy point out that I could have made a face out of that first pic Maybe I'll try when I get home - would have sort of a South American Indian look to it I think! Perhaps the art world would appreciate the human reference from the cold hard steel parts.....

If there was enough interest, we could produce the 21mm bar. We almost did when we decided to build the 5 way 19 (3/4") , since the 21 (7/8") was going to be 85% stiffer, and that sounded like to much. You can stiffen the bar by going to solid bushings and get about the same thing so it didn't make sense. More or less a 19 with solid = 21 with rubber. Or so said the bar manufacturer. Since there isn't a rubber for a 21, either that would have to be molded, or solid which would make it even stiffer. Since there is a typical front to rear ratio to work around, a 21 on the rear would/should require something larger then a 30 on the front.

Josh B

I was curious about that - wonder how things were setup on the cup cars where the 21/30 ratio worked?

Luis de Prat

Hi Mike,

Wasn't the 30mm front/21mm rear the Turbo Cup set up or did I miss something?

I just experienced slight oversteer in the rain with my cranked up 19mm rear and 30mm front, which is why I'm curious...

Mike Lindsey

I don't know what the Turbo Cup ran. The question must be asked what
spring rates and torsion bars did they run. There are two schools of
sway bars. If you look at NASCAR, some run little bars and lots of spring,
and some run Huge bars and much lighter springs. They both work obviously
or they wouldn't be there. I would imagine you could mix that up front to
rear. So you "may" have to change your rear or front springs to sucessfully
run a 21 rear bar. Haven't tried it...

Going from a 16 to a 19 would be a similiar increase as going 19 to 21. Who has put on a 19 rear, or added solid bushings to their 16 rear, and left the front alone with the original front bar and rubber bushings and got a improvement in handling?
