Hmmm,
It's a difficult one really, I think I only ever broke one of the 'Old Style' front wishbones. But you can never crash like someone else can, or replicate their incident.

There are some new revised ones which come standard in the WCE kit, the part number for the best value is HB61588. You get most of the impotant stuff that stops your car breaking in one neat package.

I'm assuming here you have the old kit, please correct me if I'm wrong.

Bert raises a good point, it's better to have the w/bone break or something else more expensive will break.

Other than that I think most people have found the car pretty bullet proof.
