Im building an LS swapped 75 280Z and i had a couple of questions. First was where are the major breaking points on an s30 chassis. When i put power down to the wheels i want to know nothing or very little will break/crack. I only plan on 600 horses in the end and im going to build up to it. I got the chassis for free and the motor i got for 300$ just tossing in a cam and some better con rods. Anyways. I do plan on doing a tubular front end because its bent in slightly. Nothing else about the frame seems bad or out of alignment thankfully. And i also plan on doing an 8 point cage as well. My second question is does anyone hace any dimensions for the front core support. I want to rebuild it and need proper dimensions. Thank you for your time to all who read this!
