no it's not on a uni budget and at the moment is not my only car but will be soon having to sell other car to buy a house which means my own large shed and possibilities for another car probably another 120y coupe and turn it into a ute with a half cage i'm quite tall and don't fit into a 1200 ute the diff and brake idea is cool any suggestions? but due to lots of driving in 100/110 zones my car calls for a fifth gear. if the diff change helps that then i'll go for that option but i doubt it the brakes are always a good idea but do you have to get them checked by a engineer if you change them? just tell me if there are too many questions
