It's hard for me to let some things go. I'm still looking for better bushings for the Catera. I exchanged emails with Bob Chen, an Omega owner in Taiwan. He has used BMW M5 (E34) bushings successfully in his Omega. This bushing is the BMW's upper/rear bushing but it's identical to the Catera's front/horizontal in size. It will work. BMW Part number 31122226528. Now that I knew which bushing would fit I took it a step further and searched the E34 aftermarket looking for better than stock BMW and found the following.
The following Meyle bushings are for the Opel Omega and fit the Catera. Instead of subbing for only the front/horizontal bushing, like the BMW bushing, they replace all the major bushings in the front and rear suspensions. I can't confirm if they are Heavy Duty or not. Maybe our Omega owner cousins know. http://www.meyle.com/Home/applicatio...a=14201772640&
Korman Autoworks is a BMW specialist in North Carolina. I don't know whose bushing they sell. Those interested can call. They also sell BMW M5 anti-sway bar bushings but I can't confirm they'll fit the Catera. The bar diameter (26mm) is the same for both cars but I can't find the other dimensions for either car's ASB bushings.

As for Polyurethane Bushings, I'm beginning to think they're not the way to go. At least not in the front suspension. For a track car maybe but the more I read the more I believe they would ruin the excellent ride quality our cars have. I plan to replace the front struts and rear shock absorbers with Koni Sport units when the time comes and with polybushings I'm afraid the ride would be unbearable. Another thing. With one horizontal BMW polybushing and one GM rubber vertical bushing I'm afraid the rubber one will wear even faster than normal. Having said that I did find a polybushing for the Catera front suspension. Powerflex: PFF5-601 (#1 in the diagram). http://www.powerflex.co.uk/products....y=9&submit1=GO
The rear suspension is a different story. The trailing arms don't deal with cornering or braking the same way the front wishbones do. Polyurethane bushings don't change the ride characteristics as much and with built in eccentrics it's easier to adjust the camber and reduce tire wear. Especially in lowered cars. They're designed to provide a camber adjustment range of an additional +/-1.0 degree above base settings to help meet the wheel alignment specs. Being polybushings they also improve handling by reducing the slop in the rear arms. Whiteline Automotive and Super Pro Camber Adjustment Kits are polyurethane bushings for the Holden Commodore (VT) and fit the Catera' rear trailing arms.
Whiteline's KCA384 kit contains the following hardware parts:
4 x polyurethane bushes, 2 x metal crush tubes, 2 x high tensile bolts, short, 2 x high tensile bolts, long
2 x nuts, 4 x spring washers, 1 x grease bag https://www.whiteline.com.au/store/d...sp?part=KCA384
What.........you trying to kill me.........feeding my addiction? Seriously, thanks for the links. Man what I would do if I had the money. Unfortunately I'm on a fixed income right now so mine are strictly budget mods. But if I had the money................
When I first posted I didn't look at all the pictures, now that I look at them I realized that BMW actually designed that bushing to compress. On a bumpy road you want the wheel to go up and down vertically without camber change however under hi cornering you want more negative camber. The BMW bushing allows this because on the bumpy road there is not much side load so the camber will not change, but in a fast corner there is lots of side load and the bushing will compress and allow the upper arm to come in closer to the body increasing the negative camber and thus the tire is planted better on the road. Installing this bushing in our front control arms would cause them to change toe under sever forces. Probably not noticeable on the street unless you hit a very large pot hole but under performance driving conditions it would cause bump steer.
I'm a big fan of poly in street applications, provided they are used correctly. Front vertical bushing is NO place to put poly, but the horizontal bushing would be fine. Also remember the poly bushings operate much differently and road fell is not as rough as people say. Under normal driving if you had two identical new cars one with rubber and one with poly I think it would be difficult to tell the difference.
HaHa Elvin you think I’m killing you! I often get together with some of the corvette forum members, one of them has a 600hp road race corvette and he gave me a ride around Mosport. And this is what I was Forced to watch last weekend http://www.youtube.com/watch?v=BbOhPCJIREY If only I had the money and room I’d love to build a dedicated race Catera, maybe in 10 years time
Another installment in my search for better Catera handling. I have found alternatives to the stock GM bushings among them a few polyurethane bushings. The rear/vertical bushing in the front control arm is still eluding me. There are springs and struts/shocks too. Even a tool to pull the old bushings out and the new ones in. Below is what I have found so far. I can't say how any of these components will affect your ride quality or handling. I can only say that they will fit.

For all intents the Catera is a German car. I found the following Meyle parts for the Opel Omega on Meyle's website.

>Are the bushings Heavy Duty (or at least better than OE)? Can Catera owners order them from you? I've emailed Meyle but haven't received a reply. I browsed the Meyle site and found a ton of other parts but I'll start with these. We have no source of parts, replacement or performance, other than GM. I hope you and Meyle can help us out.

I received a quick reply though it wasn't the one I hoped for.

Hi Elvin
My distributers in the US don't carry the parts you request. I assume this is because demand is weak. I will forward your e-mail to meyles US sales rep and ask if there is anyway to help out.
Thanks
John
Maybe someone at Meyle will realize they have a market for Opel Omega parts in the US. In the meantime we can order Meyle's Heavy Duty BMW M5 bushings. That's better than nothing I guess.
This has gotten totally out of control. Where before I couldn't find any options to the stock Catera Sport suspension parts from GM, now there's an abundance of choices. Beware. A lot of this is guess work. Since we now know that GTO front & rear springs and rear shock absorbers will fit the Catera I'm assuming that aftermarket GTO springs and shocks will fit also. There's no good reason they shouldn't but to be on the safe side I feel I must warn you. Same goes for the BMW front bushings and Commodore rear bushings. I trust the info I've received from other owners but that's me.

"Our exclusive street performance bushings and mounts are made with a more forgiving urethane formula! During spirited driving, polyurethane bushings and mounts provide more responsive handling and maintain better control over suspension geometry than stock bushings. Along with this improvement in handling, though, comes a stiffer ride -- a welcome side-effect on a smooth race track, but much more noticeable on the streets. Our street performance urethane is formulated with a touch of polyester. This new compound is more forgiving than 100% urethane, so it’s better for street BMWs."

Once again I want to thank you for helping me find some front horizontal lower control arm bushings for my Catera. I paid $68 a pair (including shipping) for bushing GM wanted $89 each for. Unbelievable... I read your entire post, watched your video (which was pretty cool), and I know at the time you didn’t have any new info on the rear/vertical bushing in the front control arm and I was wondering if you’ve discover any info on it yet, or at least found a cheaper location to get one. My local GM dealer wants (once again) $89 each. Any help you can give me is GREATLY Appreciated.
