josag Posted July 14, 2014 Share Posted July 14, 2014 Hi guys First post on Hybrid Z. Sorry if I am in the wrong place, but I wasn't seeing much v8 stuff in the suspension section. As stated, I am dropping a lq4 in my 72 240z. I am looking for some opinions on rear suspension setups. My original plans were to do a 9-inch center with a chevelle-style 4 link. Many people have recommended I look into a 8.8 IRS setup. I am mostly interested in the 9-inch for durability. Have any of you gone with live axle and wish you hadn't? I guess my inclination towards the 9-inch is because I could buy a custom housing and axle package for the price of custom cv half shafts for the 8.8. Any advice would be appreciated. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
mattd428 Posted July 14, 2014 Share Posted July 14, 2014 Do the solid axle is my vote. I broke at least one axle a week in the stock setup. My 8.8 is holding strong.......for now. Quote Link to comment Share on other sites More sharing options...
Meatwad Posted July 14, 2014 Share Posted July 14, 2014 I like irs, but if you're not auto-crossing your vehicle, just 9" swap it. Even then, you can make a live axle hand well. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted July 14, 2014 Share Posted July 14, 2014 Go ahead an 9" it and be done. Quote Link to comment Share on other sites More sharing options...
SUNNY Z Posted July 14, 2014 Share Posted July 14, 2014 If you're going in a straight line, do a live axle. 8.8's can be just as reliable (and cheaper) than a 9". Quote Link to comment Share on other sites More sharing options...

I will be wanting to auto-cross some, as well as just have a nice driver to take out at times. Have you or others been successful with a properly aligned 9-inch in autox? If I were to go with IRS, I would probably be looking into something modular I could swap in as a whole unit from a newer vehicle. Any recommendations for that?

How long have you been running the 8.8 setup? If you don't mind me asking, how much did you dish out for your setup? Quote Link to comment Share on other sites More sharing options...
mattd428 Posted July 14, 2014 Share Posted July 14, 2014 First swap was about 6 months. With the turbo I changed the whole 4 link setup I've put maybe 500 miles worth of burn outs on it. I paid $160 for the 8.8 $300 on axles. You will have to narrow it by about 7-8 inches. I had a 4 link and coil overs sitting here so it didn't cost me much.
