hi, i'm a big fan of the s30, although i'm also a big fan of technology. my dream would be to get an s30 for daily use but without putting my physical integrity at risk. I know that many people will not like my project, but I would still like them to help me get it or plan it. My main plan is to find a 280z, since from what I understand it is safer than the 240 and the 260 is the one I like the least of the 3, do a ls swap, modernize as much as possible, such as: Suspension , brakes, tires, power steering, abs and ebd, traction control if necessary, etc. mainly everything that is mechanically safer, and inside is where most people are going to hate me, but I would like to modernize it as much as possible, adding seat belts, either 3 or 4 points, a modern steering wheel with airbags and this is where I mainly get the doubt, which parts of the chassis should I reinforce to make the car safer, I have thought of a roll cage, but I find it very ugly and I am not going to use it very extreme, but if it happens to have an accident, don't die crushed by the chassis, a balance between the 2, I have seen that there are some hidden cages that make the main pillars of the cabin stronger. What else do you recommend? something to the steering column, something to the seats, whatever. I would really appreciate your help, if the z are beautiful cars and they are historical but I also really like the design and I would love to have one 100% of my style. I apologize in advance if there is a problem with the writing, please use the google translator.
