Has anyone used an ultra racing anti roll bar?

ebay

Don't think anyone has used it, but it's the same thickness as the Eibach ARB

It's more expensive than Whiteline but it comes with a set of brackets.

Hefty shipping costs...

I have used those before and they worked well and quite solid at 23mm. They are quite affordable here in Malaysia.

I have since changed to the 22mm Whiteline simply because there were cases of failure. They literally broke in half. Apparently measures were taken to improve quality on the current units. I didn't want to find out the hard way which batch I had.

That being said, when I replaced the Ultra Racing with my current Whiteline, they were in good shape. And I feel the 1mm I lost did make it less sharper. Or maybe it's just in my head.

I've just moved from 23mm to 24mm and I can feel the difference - its getting quite pointy now

Did you make your own brackets or did you manage to buy some?
