emeraldlion Posted May 12, 2010 Share Posted May 12, 2010 I've been sifting through post after post recently. I want to put in subframe connectors in my newly acquired 280z in an attempt to stiffen things up for my future ls1 swap. My car will not be a track car, just ocasional autox. I found a fellow hybridz member who has offered to weld in paraska style subframes for reasonable price, but I'm worried about keeping things level and square. From what I'm reading installing rails in this fashion is more complicated than it appears. I read in one thread someone suggesting welding subframe connectors flush against the rockers front to rear. I'm wondering if anyone has more insight on the possiblities of this method, and if it is an option where would you tie the front and rear together?

A lot depends on the condition of your car to begin with. If its structurally sound, the floor pans are reasonably flat, and the car hasn't been in any big wrecks then you should be able to weld the subframe connectors in just fine after leveling the car.

emeraldlion Posted May 12, 2010 Author Share Posted May 12, 2010 Thank you John, that alleviates some of my concerns. I tend to run towards the paranoid anal retentive side of things(which isn't always a bad thing I'm sure. So would I be correct in assuming that when it was mentioned running the subframe connectors along the rockers it would be in conjuction with tying those into a cage or roll bar to create subframe connectors?

Subframes connectors are installed to connect the subframes, not reinforce the rocker panels. A straight line is best so run them straight back from the front to the rear.

emeraldlion Posted May 12, 2010 Author Share Posted May 12, 2010 That's what I had read and always known to be true( mostly from older 1st gen camaros). When I was reading through the thread about "what would you change next time" someone mentioned they would run the square tube tight along the rockers, maybe I misread somehow.

Cable Posted June 19, 2010 Share Posted June 19, 2010 Who sells 280z subframe connectors these days? Quote Link to comment Share on other sites More sharing options...
emeraldlion Posted June 19, 2010 Author Share Posted June 19, 2010 (edited) Cable as far as I know no one sells 280z sfc. I think you can make the bad dog connectors work if you change to a rear mount style rear sway bar. The bad dog rears interfere with the mounts. It's either this route or fab up your own similar to pparakska's design. Cut the top off the tubing and use it as a cap instead of in-floor design. Anyone else please feel free to chime in but this is what my searching has resulted. Edited June 19, 2010 by emeraldlion Quote Link to comment Share on other sites More sharing options...
