I've just fitted one to mine. Used the Oreca boss from K-Tec and the wheel is not quite centered so feels like tracking out when on the road...tracking is fine.. What boss did you use as could be Oreca haven't machined it bob on.
I've not changed the wheel on the Clio but have other cars and had that issue, just wasn't on the right spline. Remove and rotate fractionally to fit the next spline surely will be the fix.
