im posting this for a friend which is purchasing the lamborghini door kit for his 95 civic coupe ex. Ive heard many different things about these kits that they must have masive amount of modifying even with the kits. Is it true that an extensive amount of welding is a must to make this conversion wrk? Or is it simply a bolt on kit ready to roll. If anyone has ever accomplished this please give me the facts about what must be done to make this a clean conversion.
