Due to countless threads on here, i have taken time to explain the differences.
These wishbones for the RS 225/R26/R26.r are only supplied by renault.
yes if you phone look on ebay etc. they are listed as non gen.
but thats due to them all thinking they have the same arm. which the DO NOT.
this is a megane RS wishbone the 2 rear circles are the differenaces. the ball joint has a tread on the taper where a nut would go on too.
the red circle to the right is where the anti rotation link goes though.
you can see in this image how the nut sits on the plate that goes over the tapered part of the ball joint.
normal megane.- you can now see the normal megane 2 has a pinch bolt and nut that goes though the hub assembly and a little cut out in the ball joint to hold it in place.
also there is no hole for the anti rotation link just for a abs wire bracket.
