Supporting mods with coilovers

true style = spring wrapped around damper



with this style you need SPL toe arms

OEM or "divorced" style = spring separate from damper, in a bucket on one of the arms



With this style you need the SPL Mid-link
https://www.splparts.com/products/re...-370z-g37.html

BE AWARE - these two different setups require different spring rates in the rear. As they have different geometry, you need roughly half the stiffness in the true type as in the OEM type. IE, a 10kg spring in rear for the OEM type is about the same as a 5 kg rear spring in true type. There is math involved, don't ask me.


EDIT:
When you get the rear suspension arms you also need to get the Eccentric Lockout kit:

These are important because once you have all these adjustable arms, you want to use THEM for adjusting alignment. The factory setup in the rear uses two eccentric bolts on each side; these will slip and **** up your alignment. You no longer need the adjustment point so locking them in place eliminates that weak point

Optional, you don't NEED to replace these:

These are simply convenient to install when the car is up and you're doing an alignment.

I really enjoyed reading the thread. However, I have a question please ...

If my stock car came with divorced style suspension, can I change it to true style? If yes, then what extra I need to order to replace the mid link?

If not then, I need to stick to divorced style then. In this case.

In both cases, since my budget is limited, which adjustable coilover you guys recommend, because BC racing ones are expensive comparing to others like KW and Tien.

Kindly advise

Thanks ..

There are a lot of options out there, what are your intentions with your car? Street/Track/Mixed? What is your budget? Are you looking to just lower the car? Are you looking to improve performance? The answer to these questions will provide further clarification and impact the recommendations you may receive.

Just get these and be done!

Apologies for hijacking the thread, but what makes these/this brand special?

I will try to answer the questions and give you an idea.

Track and weekend.
Lower to improve the handling for sure.
And make it more stiff (adjustable).
Budget for coilovers (alone) upto 1100usd.

Other items, I might get spl for more adjustments. Which will be later. Currently I want to get the coilovers.

My question is, shall I keep it divorced style or true style?

Thanks,
NAS
