How do you guys build/setup your front suspension? I am talking about the AE dynamic strut type. Is there a secret dimension to set the post (steel post where spring is mounted)? Is this post supposed to be fixed? Mine is tight. I read where people were polishing them. If it's fixed, why polish it?

I just got a new L4 to try. Most people around here use the L4 or some conversion of it so I thought I would give it a try. Are there any things I should do or not do when building this car? What about options I should or shouldn't try?

Thanks,
Jim
