SleeperZ Posted April 24, 2003 Share Posted April 24, 2003 I am fairly clumsy at using the search engine yet, so I couldn't find what I'm looking for. The 280Z has a higher ride height from government imposed ride height requirements. The 240Z has a nice stock ride height. My 280 has 1" lower Eibach springs, and still sits up fairly high in the back - really, there is quite a rake. What component in the Z rear suspension is different between the 240 and 280 that determines the ride height? If it is just the top cap, maybe I can swap in a 240 unit to get a little bit lower and even out the ride height? Quote Link to comment Share on other sites More sharing options...
Synlubes Posted April 25, 2003 Share Posted April 25, 2003 Yes, The rear 280 shock caps are bigger / taller than 240 / 260. Just replace them with the early shock caps and you can drop the rear a inch (maybe a tad more) with no suspension changes. Quote Link to comment Share on other sites More sharing options...
Owen Posted April 25, 2003 Share Posted April 25, 2003 I'll post this for my friend as he's probably still asleep.... His '73 Z was at a level ride height, he said he changed out the sway bar links and after that the car was higher in the front. A couple of months later, I helped him put in new springs and shocks and now the car is more level (the sway bar links weren't tightened real tight). Another friend and I could only guess that the upper mounts could be the culprit as everything else on the strut is not adjustable. Is there really that much of a difference between the two mounts? Thanks, Owen Quote Link to comment Share on other sites More sharing options...

Synlubes Posted April 25, 2003 Share Posted April 25, 2003 Tim, The front mounts are the same. Front and rear 240 / 260 and front 280, all the same. Quote Link to comment Share on other sites More sharing options...

S30Z Bushido Posted April 25, 2003 Share Posted April 25, 2003 so, in order to get a 280z to sit like a 240z all you would have to do is change the upper mount? how hard would this be? Quote Link to comment Share on other sites More sharing options...
Tim240z Posted April 25, 2003 Share Posted April 25, 2003 Really really easy if you have coilovers Quote Link to comment Share on other sites More sharing options...

Not hard at all if you can get the spindle pins out Quote Link to comment Share on other sites More sharing options...
Guest zfan Posted May 2, 2003 Share Posted May 2, 2003 This post is interesting,as my 240Z sits too low in the back. I may do the reverse and put 280 caps in my 240. I have tried different springs, struts and all sit too damn low. I have currently Arizona Z springs and Tokico blue struts/non adjustable and with 225/60-15's they scrape when I go over bumps or just a road with light dips. especially with two people in the car. I have the old unknown springs that were in it until recently and they are 14" springs which is two inches taller than the Arizona Z spring but they are to soft unfortunatly. If they were stiffer I would just keep them as they give great ride hidthe but just to sloppy over bumps, tracks etc.. Mike Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted May 2, 2003 Share Posted May 2, 2003 Why do you need to take the spindle pins out? I did my struts many years ago and I know I have never separated the control arm from the strut assembly. Quote Link to comment Share on other sites More sharing options...

I did my struts many years ago and I know I have never separated the control arm from the strut assembly. Because you have to compress down the rear struts on the control arms, and try to yank the tops from out of the fender. This usually means you disconnect the brake lines, the half shafts and the stabilizer bar. It was just a PITA, and with a good tool now available, you don't have to do it.

72zcar Posted May 3, 2003 Share Posted May 3, 2003 front nothing, back brake lines... thats it. done it many times Quote Link to comment Share on other sites More sharing options...
Mudge Posted May 3, 2003 Share Posted May 3, 2003 Without dropping the suspension or getting the spindle pins out, its pretty tough. I leaned on my suspension after getting the springs compressed to get mine out and it was still a bit sticky, pulled down on the rubber top to get the thing out. Putting them back in wasn't much fun either, especially when I had to do it a second time for both sides. To make it "easy" I'd just drop the strut assembly with the A arm and drum yada yada, probably take about the same length of time just less swearing.

72zcar Posted May 3, 2003 Share Posted May 3, 2003 And you are right, with the stock 14 inch slinkies i did have to disconnect the halfshaft at the wheel. With the shorter stiffer springs its not needed. But if you are taking off those slinkies .. make your life easy and drop the the brake line and halfshafts for sure in the back. ... after slinkies gone bye bye front nothing back brake lines only for sure.
