Ok guys I know this is a problem for alot of people but I think mine is an easy one. So I bought my mp-8 used from a guy and he did not give me the shims. He said he called and talked to ts-performance to get the correct ones but im thinking no. What size should they be? Dont they need to go deep into the plug where the spring sits? the ones he gave me are almost a 1/2 in. Way too big, so my question is can I just go to the hardware store and pick up some brass or stainless ones that will fit. How perfect do these need to be?

Did you get the plug seated correctly and torqued to spec? I have heard it needs to be in there REALLY tight not sure of the spec though.
