Just wondering if anyone knows if a strutbrace from an f25a Diamante will fit a 3rd gen magna and also if not what else is there besides whiteline to suit?

F25A is effectively our second gen so no it would not fit. Strut top plates are the same bolt configuration but I am very certain that the strut towers have a significant difference in width

Give Megatron a go, he may still have access to them

Cusco make an adjustable one which is readily available ,will priced too , do you know how much further apart the 3rd gen towers are apart?

I can't find any cusco ones. Their website is also hopeless.

Rhdjapan.com they have them listed for both the front and rear of a f25a diamante but nothing for a f31a
