IROC Wonderbar
Everytime I write that word it makes me think Wonderbra... lol. Anyway. The other day I bid on a wonderbar for my car on Ebay. This was a piece included on TAs and IROCs so my car was without it. But I thought I would post here what a difference in handling it made! If you guys are running wider tires like 16x8 like I am, you're aware of how the car sometimes likes to follow grooves in the road. For some reason this really helped the car! Also I have a stronger feeling in the steering wheel. It feels might tighter and more responsive.
The reason I post this in the V6 board is becuase all of our cars don't have this part and the installation is a little different becuase of our cars being V6s. The lower radiator hose braket will need to be moved out approx. 1" so that it clears where the wonderbar runs directly across. That was the only modification needed. Othewise all that was needed to be done was disconnect the front sway bar at both sides, put the wonderbar on top of the swaybar mounts, and bolt them both back down together. Next is when I extended the bracket an inch by adding galvanized metal extentions to both sides. Then put the radiator hose back in and presto!
If this interests you guys or you'd like pictures or more information let me know and I'd gladly snap some pictures and such. I just thought I would contribute this to you guys.

I agree the wonder, uh, bar, gives much improvement. Quick question, since you had to unbolt your front sway bar anyway, did you put new bushings in there? On my Sport Coupe, I upgraded to 36mm front, 24mm rear sway bars, wonderBAR, new bushings and end links. Now that made a hell of a difference.
Still, ain't nuthin like an IROC

If that doesn't work just go to Spohn's Website and navigate your way there.

Attached is the picture from the auction I won. I didn't think to take another picture of it before installing it. I will try to take some pictures of it today from under the car of it installed. Also here is a link to another one that is up for bidding on Ebay.

Thanks for the link.
That wonderbar is close to mine. The holes on mine were smaller, and painted gray. Cross rod looks about the same.
I noticed a MAJOR improvment just in that part. Let alone if I was to install a STD, and the Iroc sways.
Best 40 bux I have spent on this car so far

Nothing for nothing, but are you sure we are talking about the same thing? The brace known as the "wonderbar" has been discontinued for some time. There is another brace now with the same part number (I believe it is a fender brace or something liked that). Were you able to get the "wonderbar" from from GMPARTS Direct. Or were you using the part number to search. I kinda got caught up in the same situation about 6 or 8 months ago. I finally ordered one from Top Down Solutions out in California. See Ya.............

The hose did not need to be disconnected. All I had to do was take the house out of the bracket then unmount the bracket and then straighten them then add a new 90 degree bend with holes and remount. This will extend the bracket out approx. 1" and out far enough not to interfere with the wonderbar. Then simply place the hose back into the bracket and presto!

I have the rubber molded hoses. By relocating the hose it did not effect the cooling at all and did not put a strain on the hose or anything. The bends are all still normal and not pinched. Here are finally some pictures from under the car. I lowered the resolution on these to make them 56K friendly. I have the high resolution ones though if someone would like a better look.
In this picture you can see the newly relocated lower coolant hose. It is now right above the front lower strut bar. Where as before it was right where the wonderbar now runs.
This is another angle showing it.

You guys with the 3.1 V6's have a different radiator hose routing. My 2.8's lower hose goes into the radiator on the driver's side. If anyone has a wonderbar on a 2.8 I would like to know if you had problems fitting it by the hose. Otherwise I am going to call up the place that sells them and ask what they know.

Close to mine, I bent mine so it is ABOVE the wonderbar, not behind it. But I guess its 50/50, its outta the way, either way. Some hand bending with a few cuss words took care of it
I am MUCH pleased with my 40 bux, and recommend it to anyone that has the wennie sway bars like us.

Make sure you slide in the wonderbar on the driver's side first, then the passenger's side last; this will make the job a LOT easier since space is pretty tight on the driver's side.
Also if you are using a stock GM wonderbar, make sure the open ends of the wonderbar sleeves and the weld marks are facing up, and the covered part of the bar is facing down, as I don't think it will work the other way around, plus that's the way it was installed on the IROC I removed it from. A friend of mine did it successfully upside down, but that was on a V8 where there is no hose in the way. ( see his pics here, if interested : http://www.geezernet.nu/transam/ud0401/wonderbar.html )
Below is a picture of the post-installation on my 2.8 mpfi. It's the black bar running down the center of the pic. Hope this helps, GT
