Cusco LCA Bolt - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

afohlin · 12-09-2015, 12:45 PM

I bought a set of Cusco LCA's used and they didn't come with any hardware. I reused the stock bolts but the outer bolt from the LCA to the knuckle is too short. Does anyone know the correct size of the bolt that comes with the Cusco LCA's, or at least the size of the stock bolt so I can get one that's a little longer?

I do not know the specific size for the Cusco arms, but the OEM bolt is M12x1.25. We use 90mm length for our rear lower control arms, but that is longer than needed for the Cusco arm. I would suggest 80mm in length, and the more common thread pitch at most hardware stores will be M12x1.75.

Hope that helps.

Thank you!!! I checked Home Depot, Lowes and Fastenal and could only find M12x1.75. I bought both 80MM and 90MM, plus washers and nyloc nuts. I'll install this weekend and will feel a lot better about having the right hardware
