We'll leadsled if you do shed 5 and unless you have that you will so sb etc o your lbs you don't have to do them. However if you doing it iaw manufactures you have to. The only time a sb is mandated is if it was an AD but clearly your nose bleed must have covered you eyes from being up so high in your seat. And as for tell you to suck eggs maybe you should take some note or what a a low life spanner swinger is someone you can take note of.
