I talked to the dealer again today, this time with a mechanic who'd been there for 10+ years. He said they never fit turning limiters unless the customer asks them too, they've never had any rubbing issues.
So based on that, as well as the experience you guys have I'm going to not have turning limiters fitted.
My car was ordered with standard 16" tyres so no turning limiters fitted from factory, now I have 17" 205/40 and Eibach springs fitted (-35mm) and no problem at all with rubing without these limiters...
Thanks for the answer, this is exactly the kind of information I was hoping for
In Denmark the Zetec S is already lowered 25mm yeah. And I agree they probably wouldn't sell something that'd breach the warranty, however they specifically told me Ford recommened turning limiters, so I'm kinda confused :-D
Guess you're right, though my Civic copes quite well with bumps on its 225/45-17 so I can't image the 45s would be that bad on the Fiesta (unless of course its suspension is worse than a Civic)
