Why are Stage 8's so hard to install?
 

Just wondering, I just picked up a set of these from ebay for $40.. I've read in many places that these take alot of patience to install. Is it the clips that are hard to put on or something? I'm having a shop do it, but I want to be able to give them a heads up, and at least have some idea of what they are up against.

Thanks!

I've been told to make sure that you run a tap through all the holes in the head first and make sure you can easily thread the stage 8's in by hand before attemping the install. It makes it way eaiser to install and lowers the chance of a cross thread.

Ok, that makes some sense. I will advise the shop to do that -- I really don't want them to be cross threading, that would definitely fall into the "bad" category.

Thanks
