What inserts for m4 at storm valley

[jon kedge]

Just got a full set of m4 holeshots for my 4wd as one of are regionals is there.Do you run the inserts that come with them(the front insert is the same as the rear )or some thing else,do you cut the edges off to help the trye profile,trying to keep the tyre cost of this meeting down as it's a one off for me.Any help much appreciated,, jon kedge

For a one off meeting just trim the inserts in the front and take the edges off the rear to get the profile of you can buy the aka red molded inserts but this adds to cost.
