Supporting mods with coilovers

GooglyMoogly · 05-23-2020, 05:15 PM

Hey guys looking to buy some coil over soon but reading through the forums I learned that there are bunch of other things I need to get to fix the alignment after lowering the car. So far, if I read correctly, these are the things I need:

1. Front Upper Camber/Caster Arms
2. Rear Camber Arms
3. Rear Traction Arms

Are these mods the correct ones and what other ones do I need? Also z1 has a package, but I heard SPL stuff is higher quality. Is the difference a lot? SPL seems 2-3 times the price

Thanks

SPL parts flat out works. The best quality. The easiest to adjust. They hold their adjustment. The most recommended parts on this forum. Buy once and forget it.

OptionZero · 05-23-2020, 09:03 PM

SPL has more adjustment range and much better track record of reliability, plus easy on-car adjustment. Its not even a question - SPL is the best option. Dont cheap out

You also need either the toe arm for true type coilover or midlinks for OEM type

Z1 has documented- self admitted manufacturing issues for at least one run

Don't believe me? Read yourself Z1 front adjustable camber arms

Oh, and the Z1's aren't adjustable on car. Gotta take 'em off. Oops

we always recommend SPL because they are the best

Awesome, makes sense. One last question, what’s true style and oem style? Bc and kws are like oem right ?

OptionZero · 05-23-2020, 10:58 PM

true style = spring wrapped around damper

with this style you need SPL toe arms

https://www.splparts.com/products/re...-370z-g37.html

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:
https://www.splparts.com/products/ec...-370z-g37.html

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:
https://www.splparts.com/products/bu...-370z-g37.html

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

A word of advice - do not cheap out on alignment components!!! Do it once- do it RIGHT. SPL all the way. The other **** is 2-3x cheaper for a reason. I got true rear coils and am very pleased with the ride and adjustability.

GooglyMoogly · 05-24-2020, 11:59 AM

Okay SPL stuff it is. z1 seems to be selling it cheaper than SPL website, is Okay to buy it from them? Also guys OEM style coil overs are mostly all the brand names people usually buy right ? Like bc racing, kws and rs-rs? Still a bit confused since none of the coil overs ever mention oem or true style besides couple I saw on z1 that said true style.

Yes. You can buy SPL parts from Z1. I bought almost the SPL whole catalogue from Concept Z performance. I believe they also have free shipping on these parts right now too! Check it out

BONUS TIP Use the online code ONETIME at checkout to save 10% on your order. Buy everything at once as the online code is good for only ONE use. Best wishes!

Assume OEM style unless specified otherwise. Some places offer both

Shop around and get the stuff whoever is cheapest for you. It all ships from SPL anyways

Watch the for sale section, spl stuff pops up
