I have misplaced my cusco spanner wrenches. Do anyone know if I can replace them with the generic wrenches from ebay, or a set from another brand? I can't find replacement cusco wrenches anywhere.

 

I used the cusco spanner wrenches on other coilovers. I'm sure you can use generic wrenches from ebay. Or make some yourself.

 

Wrenches from another company (Tein, HKS etc...) will work fine, as long as the diameter of the coilover perch is the same as the wrench is meant to fit. Too big of a wrench can cause it to slip while turning and will chew the hell out of the perch channels.
