70 duster: updating, and a no-dough pro-touring makeover

can you explain to me what ill see with scrub radius,what ill experience, and if it will be detrimental to tire wear, turning radius, handling, etc?
and while your at it, can you make it in laymans terms? i googled it and got baffled pretty quick. this is a new suspension geometry point that im not familiar with.

thanks
