when you go over a bump the car will try to steer into the bump if thats not bumpsteer what is it??
anyone remember the carlos fandango ad with the anglia with oversize wheels!!

Using too small an offset will increase the scrub radius, not necessarily a bad thing until you get a blowout. It will increase the 'feel' of the steering, the self centring. It wont affect the bumpsteer, that is where the different geometry of the track control arm to wishbones will cause a steering input as the hub assembly rises and falls.

as i said before you need to consider the centre of the contact patch to where the theoretical kingpin inclination line hits the floor and this will i assure you create a badly steering car if its too far out from what is intended

Will 20mm really effect it that bad? Could put them back on ebay without a problem but I like the alloys.

Do we have a final verdict? sell or use?

If it was me then I'd keep them until I had a chance to drive the car with them on and see what it felt like. You can always sell them later if they don't work out.
