Have you only fitted springs or do you have different wheels than standard? The reason I ask is that all manufactures allow clearance for full suspension travel with standard wheels without contacting the body work.

Fitting bump stops to prevent this isn’t good. They are designed to stop your suspension fully compressing and causing metal to metal contact between suspension parts. This means that to stop the rubbing you may have to fit several bump stops to prevent the shocker compression to the point at which it contacts the bodywork. From there the only suspension you will have is how much you can compress the bump stops, it would be like solid rubber tyres on a bicycle.

I don’t know anything about rolling the arches but if all your suspension is OK then this should provide extra side clearance for the wheel.
Thanks,
Paul.

Have you changed struts or springs or both?

Eibach spring only give a small drop in ride height but are uprated so they shouldn't allow as much movement as standard springs. If your originals springs didn't rub over big bumps than the Eibachs shouldn't rub either. If you've fitted new struts as well then that should make it harder again to push the wheel into your arches.

Bump stops are the rubber thing that are fitted around the rod of the strut so you normally take of the ones off the original struts and fit them to the new ones.

Thanks,
Paul.

i had eibach springs on std shockes for 2 months but only after replacing the shocks with new KYB ones did they start to rub i dunno if the original bump stops were fitted to the new shock as i didn't fit them. I'm gonna have a look at weekend so i'll find out if the bump stops are there or not thanks for the help guys

I would check you've got the correct struts for your car as it sounds like they've altered your suspension geometry. I know on the Renault 5 turbo that the phase 1 and 2 cars had a different top mounts so if you fitted a phase 2 strut on a phase 1 car it gave you massive negative chamber. It could only be a small change in your case, but it doesn't take much to touch. Have you still got the original struts to compare with the new ones?
Thanks,
Paul.

Hi i have a 04 wagon with PFF7 wheels and Eibach springs. They only rub under extreme cornering or when carrying big rear passengers. I have been told this is due to the fact wagons have a smaller rear track so not as much clearance in the arches.

Solution = Remove rubber trim around arch and if still catches get them rolled.
