Hi I am hopeless with all the add ons just a few things i have seen spoken about and would like clarified as to what they are and what they do (any pictures would help!)

-EXTRACTORS
-HEADERS
-LSD (im guessing limited slip diff - what is the benefit?)
-TWO HOLE MOD

there is more but not coming to mind at the moment.. i'm sure all add to the list..
and anyone else with any questions please feel free to add them in

cheers
