    Shortest Struts that fit a 240z

    in Brakes, Wheels, Suspension and Chassis

    Posted

    Koni 8610-1436 or MR2 Illumina rears are very short.  I've used 8610-1437 (slightly longer than 1436's), Tokico HPs and basically all the illuminas people fit on Z's except MR2 rears because they were on back order for about 5 months.  

     

    Summit should have everything you are looking for with fairly accurate measurements.

     

    You will definitely have to section the struts.  Good luck.

    16x8 with your current tires is most likely the widest you're going to be able to feasibly use without modifying your fenders or using the perfect offset.  Just be happy with your wheel size and if you're going for a certain stretch then size down your tires.  I used to run 205/45R16 BFG Sport Comp 2s but 215s or 205/50s should be good also.

    Depends on whether or not you're running 2.5" OD coilovers or the OEM struts.  Currently running 225/50R16 on 16x8 wheels +0 offset with OEM struts, cut springs and koni inserts.  The fit is very tight.

     

    Do some searching and you'll be able to find some information about tire/wheel sizes on this forum.  

     

    Here are some good places to start:

    question about tire size vs clearance to fender with new tires and Stagg shocks and springs

    in Brakes, Wheels, Suspension and Chassis

    Posted

    Going to a 205/65R15 tire vs a 205/60R15 tire will hardly add much cushioning.  I feel like the money for a new set of slightly softer tires could spent more effectively else where such as on some nice shocks or control arm bushings.

     

    As for the springs: I've run Stagg springs and I wasn't a fan, when I tested them on my spring rate tester they tested much stiffer than advertised and they added A LOT of ride height.

    WCR axles and rear sway bar

    Delete the rear sway bar.

     

    Delete the rear bar. If you just bought it, return it. A rear bar actually hurts the Z. So you are killing yourself to add weight to the car that works against you in corners. Costs you traction exiting corners. Even if you have an LSD.

     

     

    Interesting that you guys say this, can you explain why?  I too just ordered a 1" front and 3/4" rear sway for my Z.

    I'm not sure if Longchamp XR4s come in 9.5" width, I think the widest Longchamp made them in was 7.5".

    That being said you can definitely buy some 6.5Js or 7.5Js and have a shop widen them to 9.5".  I think that's what Kenny Seo did on his 240z (before he sold it).

    Probably not.  Do the math here (.55" wire dia, 12" free length, 4.75" OD. open both ends, 9 coils).

    They can also find existing springs that match your requirements or custom make them.

     

    Very cool tool, thanks!

     

    I was referencing this thread for spring rates.

    Do I really need inverted struts?

    in Brakes, Wheels, Suspension and Chassis

    Hi all,

    I'm tackling suspension and chosen to go with a coil-over conversion.

    I've looked into companies such as Stance, BC Racing, Ground Control, and Arizona Z Car.  I notice that a big selling points for some of these companies is the inverted strut design they use for their shocks.

    From my research I've pulled the following pros and cons to inverted struts.

    Pros:
    -Shock is less prone to leaking

    -Shock body (sort of) acts as a suspension arm (in the MacPherson Strut design)

    -Even compression within the shock
    -Lower temperature of shock oil during compression

     

    Cons:
    -Clunking (a lot of Subaru guys get this, is it just an OEM shock thing?)

    -Cost

    -Adjusting the stiffness of rebound/compression is less convenient

     

    Because I don't foresee myself ever using stickier rubber than street-able r-comps (think Advan A048) and considering my car is my daily (I go to Laguna Seca twice or three times a month), would it be wiser to go the DIY Ground Control conversion route or would it be worth it to drop ~1500 dollars on Stance/Arizona Z Car coil overs?

    Thanks,
    Liam

    AP Racing Brakes

    Hi all, 

    Over the past few months I've came across a few disc brake setups for the 240z-280z chassis using AP Racing components.  I've tried to investigate these setups so I could share some information about them and perhaps use them, however, my efforts have been futile.

    If anybody has any information or guides on how to build one of these setups I would love to hear about it.

    Here are some pictures from D.S.G. Sweeden's build. (There was one more member on here who had AP Racing Brakes but I couldn't get a hold of him)
