Max, will let Ed explain the actual break. The lower wishbone is wide and gets the most punishment due to also being the location for the shock's, etc. I went over to my fabricator friend who is going to make up new re-enforced suspension arms, I already use the same ones on my Ace's / Aceca's. Also plate in the suspension arm for more strength. If they go (only second one I know about) then it is at the front which carry's the hub. When I took my old one off, found just painted which cracks off, leaving metal to the eliminates. Will be making up 10 sets of rear and front wishbones, not sure the price. Thanks John
