Difference in Eibach prokit springs??
 

Hi

I know the Eibach Pro-Kit springs are the same for the FR-S and BRZ in the US (Same product code) but are they different to the ones for the 86 for JDM, AUS spec or EURO spec cars??
I contacted Eibach australia and I've been told that the prokit springs released in USDM are different to the world market? I smell lies.. does anyone know anything about this??

I can have them post in here and tell us. Bump this tomorrow in case I forget.

thank you, will do:party0030:

OK I'll send this over to Tony Jackson now. He's an Eibach employee and is a member here. He'll be able to answer it. :thumbup:

Typically this is the case. At Eibach North America we do all of our designing and testing around USDM cars and produce the springs here for our market.

Eibach Germany also does their own testing, designing and production for European and Asian market cars. I believe all of the kits for these markets have to be TUV certified so the specs and part numbers will vary between our two markets. In some small cases we do share the same spring application.

I haven't seen any specs from Germany on the GT86 kits yet but I'll shoot them an email to see what their plans are.

Thanks for your info Tony, can you please also find out if the kits are interchangeable, meaning US spec prokits can fit on jdm/aus spec cars and vice versa?

From the forums, I know the 86, FR-S, and BRZ all have diff spring rates and if the BRZ (US spec) and the FR-S (US spec) can use the same US spec prokits, I'm guessing they'll fit the 86 here in Aus or for the fact every spec in the world?


SPRINGS Front/Rate Rear/Rate
OEM Toyota 86 3.0k 3.3k
OEM Scion FR-S 2.3k 3.8k
OEM Subaru BRZ M/T 2.7k 3.5k
OEM Subaru BRZ A/T 2.7k 3.5k

Bit off topic but can you point me to where you got that info? Wanting to know if the source also talks about damping differences and if there are differences between different market 86s/GT86s.
And I had no idea the FR-S front and rear were so unbalanced compared to the 86 - I assumed they were the same. Now I feel like I have a car made for dorifto kids. :brokenheart:
Oh well, that can be changed easily.

People need to understand that the motion ratio (leverage) of the rear suspension basically 'softens' the rear rate.

It is not unbalanced.

But the FR-S front:rear ratio is quite different from the 86. So assuming one of them is balanced, the other is unbalanced... or should we say "less balanced."

its in the BRZ/FR-S Suspension Options List (Springs and Coilovers) sticky

We'll know sooner or later but this information has to be passed down from the other Eibach groups once fitment is confirmed. ie; Eibach Germany, Eibach Austrailia, Eibach Japan, etc. I'll post up once I know for sure.

Hi all,

Below is our reply to LeeJ who unkindly accused Eibach Australia of lying.

As you can see from our email to LeeJ and the reply in this thread from Tony Jackson at Eibach USA, that we did not in fact lie to LeeJ.

We at Eibach Australia take the up most care and consideration to give the best advice to our customers, especially when it comes to new applications coming into the market.

At this stage we are aware that there are 3 versions of the 86 on the market around the world - US, Japanese and Australia. We are currently in the research stage of finding out what application - US or German will be best suited to the Australian version vehicle.

If you have any further enquiries please contact us at Eibach Australia.

Hey Eibach Australia, can you see any issues with the US kit on Australian cars?
