Most places with laser equipment also measure camber and castor, but its only info as on almost all cars its not adjustable.
Camber can be quite helpful in the handling arena so its not the end of the world, factory specs dont have to be adheired to. Infact, more camber is typically a good thing, withing reason, 3 deg is ALOT and far too much for this vehicle. but etween 1.5 and 2 is a fair amount on 50 profile tyres. But wear is a tradeoff you have to accept.
Typically camber doesnt need to be touched so long as its within a reasonable amount and 1 side isnt massively diff to the other.
The rear beams/arms on the clio are usually all over the shop, some toe out (the ones which are VERY tail happy toe out) and some toe in, i assume yours toe in from your comments.
