March 23, 201114 yr comment_350459 yeah they were at a friends warehouse. He picked them up in Maine from a Z hoard that John from Bad Dog Parts tuned our club intro. I think those parts were left outside. Here is his car with our club racer "team zero" in the background Link to comment https://www.classiczcars.com/forums/topic/38971-280z-springs-on-a-240z/?&page=2#findComment-350459 Share on other sites More sharing options...
March 23, 201114 yr comment_350494 Everything you need to know about this is located on the Hybrid Z site (sorry if this is a no no) authored by John Cofey from BetaMotorsports. I'm replacing my springs and struts on my 1972 240Z with the following: Tokico 280Z springs front and rear (8 coils front/9 coils rear) and Tokico Illumina 5 way adjustable shocks. This morning I went to a shop which does racing suspensions to confirm the compression spring rates for both the front and rear. Using the info from John and the FSM, we confirmed the following: Right front spring @ 604 lbs- no coils need to be removed; Left front spring @ 562 lbs. needs 1/4 coil removed; Rear springs measured at 703 lbs (FSM says they should be 635 lbs@8.4") so we're looking at removing .5 of a coil. Before installing I will run the compression tests again to verify. So to give credit where it's due, I got all this from John and I'm just verifying his calculations. Please read his post as it contains much valuable information.Andy Link to comment https://www.classiczcars.com/forums/topic/38971-280z-springs-on-a-240z/?&page=2#findComment-350494 Share on other sites More sharing options...
