i know this question may not go over vary well but, what is the s4 and s5? I'm guessing the s4 is 86-88 s5 is 89-92. quick some one correct me please. whats the differences and i would love to know why my last 88 SE had 4 lugs on the rims and my new 88 gxl has 5? i used to have a few sights book marked that had all that useful data no sifting required and now i cant find a thing on what i really wish to know. also not related dose anyone have a link to a good sight with the life story of the FD i can look over? I'm gearing up to buy one and id like to do some research thanks guys.

PS I'm sure I'm not the only one who has asked and i know that there will be a few that will learn something for themselves thanks to me asking lol.
