I'll stick my neck out and suggest that Nick bought his from ATP

As to whether it was direct via their german website or ebay, only he can answer... but again I will wager that it was the cheaper of the two outlets

To clarify, this isn't a dig at Nick, simply that he doesn't dick about when buying bits for his cars

Yes, bought from ATP's own website as it was a few quid cheaper. Several mouseclicks before I got dressed, and the parts arrived 3 days later. If you've had to spend hours at work chasing down out-of date/badly specified/poorly described/etc part-numbers/parts/suppliers etc, then car parts are refreshingly simple. For me a mental Venn diagram of cost/availability/convenience determines where I source parts. Buying genuine from a dealer rarely wins.


With that said, I've owned this Omega for nearly 6 years, and have bought more genuine parts for it than all of the other cars I've owned since 1988!

Nick, do you have a link to the ATP wishbones and is the site in German or English?

[Doctor Gollum]

Here do for the eBay store...

And...

You do the Math

[Doctor Gollum]

Unless the euro has collapsed today, I would go with the eBay listing... Normally the other way around so always worth cross referencing

[steve6367]

I've purchased from ATP website and eBay both worked fine so as Al says go for whats cheaper on the day

What is confusing me is that they say the brand name for those wishbones are Q1-Part and not ATP like I thought it would.

Does ATP have there own brand name wishbones? Or have they always used Q1-Part for wishbones?

Will the Q1-Part brand take the Powerflex bushes OK without braking the welds on the wishbone?

Thanks

You're over thinking a very simple thing:

They are a good price
They are convenient to buy
The quality is good enough
This makes them good value.

So, buy them. Or buy something else. It's not rocket science.

What it is Nick, I want to install the Powerflex Bushes. I've read so many horror stories about the extra stresses caused by them that has led to cracking or even breaking the welds on the wishbones. A lot of the info that I have read suggests using the original wishbones to avoid this.

Are you using front Powerflex Bushes on the same wishbones that are in the link and have you had any problems?

Those reports apply to attempts to replace the rear bush with a more durable part. The problem is not the amount of weld or quality of the metal, but that all the experiments transfer the movement from the bush to a part that can only accommodate it by flexing. The welded mild steel sheet wishbone isn't designed to do that, and will always break if you apply a lot of force often enough. And a 1700kg car does that easily.

Fitting poly front bushes doesn't alter the design, as the movement is still around the bush's central sleeve. The difference is that the parts aren't bonded together and they don't have the oil-filled cavity, so they take a lot longer to wear out. So much longer that you can expect them to last the life of the car.

Did you fit the Powerflex Bushes to yours?

I read that the Powerflex Bushes dry out over time and need regressing from time to time. Is that true?

If they do need regressing and I have to undo the nut and bolt to gain access, will I have to have the geometry redone again?

[Nick W]

Mine has had poly bushes for over five years. Used the lithium grease that came with them, and haven't touched them since.

A geometry check isn't necessary if you do have to lubricate them.

Poly bushes eliminate a number of suspension issues cheaply and easily. They are a must have part

Nick did you ever use or try the poly bushes for the front anti roll bar and if yes, what was your thoughts on them?

Fitted them at the same time. There was nothing wrong with the originals, and I've never seen any that needed replacement. As they don't locate any of the suspension like on a Ford, I wouldn't bother with them again. Plus stock rubber ones are only a couple of quid each.

Certainly on my cars I think the same applies to the ATP with stock bushes, I won't be changing them again before something else too expensive to fix fails, mainly corrosion - if you do astronomical milage or have embarked on a plan to extend the life of your Omega then I can understand the poly.

[Andy A]

I'll stick with the original Anti Roll Bar Bushes then. Save some money as well. 

I want to keep the car for as long as possible. So I'll fit the Polys on the front in the new wishbones from ATP that I've just ordered.

Thanks everyone for your help.
