SBC_400 Posted December 26, 2002 Share Posted December 26, 2002 ok, a little more info. I just got off the phone with suspension techniques, and their rates are linier, and are at 112lbs for the front, and 184lbs for the rear. however, their springs for a 280z are 182lbs front and 202lbs rear. would the 280z springs be a possibility ono a 240? still no info from tokico, i think htey are closed for the hollidays, i just keep getting voice mail.

DavyZ Posted December 26, 2002 Share Posted December 26, 2002 Yes, they can be swapped on a 240Z, no worries. I had an early 260Z with 280Z springs--fit fine. The only thing that is really different in using the coil-overs is the diameter of the strut tube--the 280 is a tad larger in diameter, so you have to get a "280Z kit" for a 280Z suspension for the threaded sleeve to fit, but the spring is a no-brainer and fits both cars. The 280Z spring is a higher rate because the 280Z is a heavier car. Davy Quote Link to comment Share on other sites More sharing options...
SBC_400 Posted December 26, 2002 Author Share Posted December 26, 2002 how will the 280z spring affect the "lowering" effect of the spring when put on a 240? Quote Link to comment Share on other sites More sharing options...
KG78Z Posted December 26, 2002 Share Posted December 26, 2002 I have Tokico springs on my 78 and I love them. They are a firmer ride but the increase in handling was amazing. This one of the first upgrades I did to my Z. I do not know any spring rates. KG78Z Quote Link to comment Share on other sites More sharing options...
Drax240z Posted December 27, 2002 Share Posted December 27, 2002 scott_d if you put the 280z springs in your 240z it will not be lowered as the 240z springs would allow. Assuming that your 240z weighs 2400lbs (1200f/1200r) stock, and a 280z weighs 2800lbs (1400f/1400r)... this means that with 280z springs in a 240z your 240z will sit 2.06" higher in the front, and 0.29" higher in the rear than it would with the 240z tokico lowering springs. You could always just cut a coil or two off however. Some might balk at doing that to a new spring. Quote Link to comment Share on other sites More sharing options...
Mudge Posted December 27, 2002 Share Posted December 27, 2002 Drax is right, a stiffer spring will resist squat more. The STs sound a bit mild, but I would have to feel it to know for sure, not alot more rate than stock except the rear but I guess thats what they found to be best during testing Quote Link to comment Share on other sites More sharing options...
SBC_400 Posted December 27, 2002 Author Share Posted December 27, 2002 ok, i need springs and struts bad, and i think coilovers are a bit out of my price range. i have researched the eibach pro kit which is aperently the only kit they make for the my car, a 71 240z. the eibach rates are 68lbs to 148lbs in the front, and the rears are 85lbs to 302lbs. I have not heard back from tokico yet about the rates of their springs. but i can get the kit, with springs and shocks for all 4 corners for 379$ with the non adjustable struts, and 559$ for all four with the illuminas which seems to be a good deal. but if the springs suck, then it is not a good deal. so i am just wondering if any one likes them, or if any one hates themso I can decide. again my car is a 71 240z with big steel fender flairs and an sbc 400. I would like some stiff lowering springs, so it will stop bottoming out. thanks scott Quote Link to comment Share on other sites More sharing options...
Mudge Posted December 27, 2002 Share Posted December 27, 2002 If you get the rates for those Tokicos post them I'm hoping they are straight rate, variable isn't too much my thing. Quote Link to comment Share on other sites More sharing options...
SBC_400 Posted December 27, 2002 Author Share Posted December 27, 2002 Ok, i just got a call back from tokico. the rates for a 240z are 140lbs front, and 165lbs rear. does this sound like a high enough rate for a hybrid z, for performance driving? would it help any more to have the illumina struts over the non adjustable tokico's? and does any one know of any lowering kits that will provide a stiffer rate than that for the 240 without going to coil overs? by the way, thanks for all the info so far, I am working on getting som pictures of my car up so I can share. scott Quote Link to comment Share on other sites More sharing options...
Mudge Posted December 27, 2002 Share Posted December 27, 2002 There is a physical difference, off the top of my head I want to say the strut ID is off by .04" or something like that, but can't recall for sure. Length may also be different but again not sure. 300ZX front strut inserts can be used also (front/rear), but strut tubes have to be shortened, also heard MR2 but dont know details.

Guest Anonymous Posted December 27, 2002 Share Posted December 27, 2002 Inside diameter of a 240 strut tube is 2.02 and a 280 Z is 2.185 By the time you get thru with the "unkown rates on the lowering springs" and the Illumina selection and, or/plus sawing up the strut tubes to get that "right lowering stance" or "cutting coils"etc etc etc and etc you are going to need 42 page list just to road map the modifications... Why not kick in a few extra bucks and get some 10 inch coilovers from members Ross or Mike in the EXACT weight rate that you can select for yourself. Slap em on there and if the 2 inch lowered they give is not your cup of tea, take a spanner wrench and spin that adjusting nut up until you are satisfied.There aint no rule that says you have to buy all this at once . Get the strut cartridges first and then the coilovers. I have heard good reports on Hypercoil coilovers Quote Link to comment Share on other sites More sharing options...
SBC_400 Posted December 28, 2002 Author Share Posted December 28, 2002 another quick question, tokico sells their springs and shocks in a kit which saves alot of money, but you cant mix and match springs and struts, that is if i got the springs for a 280, for the increased spring rate, i would have to get the struts for the 280 as well. the woman I talked to said that there was a different part # for the 280 struts, bu tshe said that it may be just because of different valving. is this true, or is there an actual physical difference in the strut?

Guest Anonymous Posted December 29, 2002 Share Posted December 29, 2002 Hi Scott. I went with the Tokiko non-adjustable struts and standard springs.......love them both. Lowered the 260 about an inch. Got them seperately (not kit) from Shox.com , $182 for the springs, $268 for the struts. If you want to mix and match 240/280 there shouldn't be a broblem outside the "kit". Quote Link to comment Share on other sites More sharing options...
