Another QSC Clutch Kit Question…

I just installed my QSC Clutch Kit and don’t get me wrong I love the performance but I have been doing some thinking. I installed the thinner spacer, (1800 rpm engagement) but this is were my question comes into play. All the talk about the primary being balanced, but when you install the spacer it’s not a great fit it is lose and goes more toward one side when you install the new spring, will that not affect the balance? Also I the secondary balanced? I can see where it was dilled as if they done it to remove weight. Thanks,
