2010 M8 Primary Spring

[Flange]

Do I have to remove the big torx in the middle?
if yes, what's the torx size ? T65 ?

No.

Went to dealer this morning, they said replacement is 0646-435 143/290lbs
its the same black with the orange stripe that came in the stock 2010 M8ho.
I am not sure I had the right info, the parts guy seems retarded a bit

I'll put it there and see how long it will last this time
