a couple of questions here
how much does the entire backseat weigh?
what kind of 1/4 times would you see from removing a backseat?
what would you do in place of the backseat?
these are my thoughts...i hate people riding in my backseat, im not a chafeur?sp?.  excrement always gets messed up back there, i even get upset if the floor mats get kicked underneath the front seats a bit, so my solution, take it out and free up some weight.  in place of it, i was thinking about a sheet of particle board/plywood cut to fit the space, and taking some grey carpeting over it.  what should be done about the hole its going to leave for the trunk though?
any ideas, suggestions, comments are welcome.

how is this a suspension/brake question?
