i notice you drive a lancer and going from a lancer to a 34 myself definately expect to spend a lot more on petrol, in terms of handling perofrmance and comfort obviously the 34 is far superior but is dearer to keep on the road, one site that does seem to have a decent size range of body kits is carmate.com however from reading what people have said about them on here they dont seem to be the best, good luck with purchasing a 34 mate!
