HOLLAATYABOYY1 Posted April 5, 2018 Share Posted April 5, 2018 If you we’re dead set on going with a solid rear axle on a 76 280z. What is the best way to go about it ? It doesn’t look like anyone sells any kits for this to make it into a 3-4 link suspension Many info would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
weedburner Posted April 6, 2018 Share Posted April 6, 2018 When I convert the FC RX-7 from IRS to solid axle, I go with a torque arm suspension. Basically a couple lower control arm chassis brackets that attach to the same place that the original IRS subframe mounted to, along with a torque arm that extends forward below the driveshaft. The nose of the TA anchors to the top of the trans tunnel (driveshaft passes thru the middle of a shackle style arrangement), easy to do in an RX-7 because there's a lot of room above the driveshaft in a piston powered RX-7. Here's a link to my page on converting the FC to solid axle... FC/8.8 Solid Axle Conversion I have also seen IRS cars converted using basically stock geometry FOX body Mustang triangulated 4 link suspension. It appeared that they simply stuck the rear under there, then fab'd chassis brackets in place to fit the links. Fox Mustang rear just happens to be the same width as the FC's IRS.

Either way I see a lot of fab in my future. Not sure I’m inclined enough many idea if the swap kit on that site will work for a s30?
