Stock JS .21 - In the US we remove the aluminum shim and only run the two cooper shims. Both these shims equal the one aluminum, which is 0.3mm[/QUOTE]

Does the "race ready" JS .21 still come with the aluminum shim and the two copper shims? I just wanted to check with everyone before I pulled the head off my relatively new "race ready" JS engine to remove the aluminum shim as Ed suggested.

Thanks
