260z - Suspension Upgrade

[phoenixt]

Hi All,

 

I currently have a 76 260z Coupe with suspension that is pretty much at the end of its life. I have been doing some searching both here and on HybridZ regarding suspension upgrades/modifications...  I have decided that i would like to have coil overs  (using a HSD kit from Otomoto) with sectioned struts, However given the parts i currently have spare ( ie not including the suspension on the car) im not sure which path to go down, so some advice would be greatly appreciated.

 

Parts i have:

a full set of 240z components (51mm strut diameter)

z31 front struts with adjustable Koni Yellow inserts (8641-1060 sport) and z32 4 sport calipers with r33 discs (blanks drilled to 4 stud). (interestingly the z31 struts are also 51mm diameter)

 

My current thinking is that the Koni Yellow inserts could be used in the 260z front struts and placed on the rear of the car without sectioning?

 

and the z31 struts could be sectioned and fitted with Koni Yellows from a Corolla and then fitted to the front?

 

If the above can work what should i be looking at for spring rates given that i intend on installing an RB30 and RB25DET gearbox in the future? (3 guesses who had an R31 in a past life )

 

Are there any advantages/ disadvantages of using 260z gear instead of 240z, other than the 260z struts are larger diameter and i assume (haven't measured) that the rear strut on the 260 is taller than that of the 240?

 

Any advice will be greatly appreciated.

 

Regards,

David

Would love to know the same answer... Looking at what are the best coil overs for 260z 2+2 for daily use with an RB25 DET.

I recommend you call Ben at Otomoto.  He is very knowledgeable and very helpful.  Yes, some would say that he has a vested interest in selling you something from his range (although his range is huge and of very good quality), but he has always been very honest with me and everyone that I know he has spoken with.  He also has a very long and broad history in vehicle modification and testing (pretty sure he was a motoring journalist for a period - was it Fast fours?)

 

Anyway, ring him and ask him all the questions.  You'll get sound advice.

FWIW, 260 struts vary. Early 260s had struts like the 240s, whereas later 260 ones were shorter & larger diameter on the front, different again at the back.
