I wonder if Ohlins would not have been a preferable choice.

I have a feeling Citroën might be working with Ohlins, as in the WTCC car and on the R5 they have their dampers (might be wrong about the WTCC though, but I remember it to be Ohlins).

Does anyone still use Bilstein?

Lots of people do.

I'm in the middle of making 04 Subaru, O5 Subaru, 97 Subaru, 94 Golf, 95 BMW and 96 BMW struts all inverted 50mm..And here in Fortress America™ I've supplied a couple of hundred cars with full suspension...I like Bilstein for one good reason: they have kept the same notational system for the valving since time began---or at least the mid 1970s when I first began disassembling and modding them... so I can look and see if 260/90 is a bit soft both ways I can go to 300/100 and I know what I'm getting..

At higher levels and for the richer wannabes they "need" double compression damping, single rebound, hydraulish puffer, and the need to spend 2 x as much..

What I'm curious is does anybody down there in NZ or "the Western Island" still use DMS?

That's why I thought that selecting a company because you know them is bit silly.

Tommi isn't stupid so I hope that's not what he has done.

hördu, everybody knows what's inside the others...Everybody would be crazy NOT to know..
There are only so many ways to skin a cat.

Way back when Kenta Öhlin there at pappas Öhlins Mekaniska Verkstand in Sollentuna when he was designing his stuff and VM250 rider Tea-Leaf Hansen from Upplands-Väsby was being the "test victim" there were on one big table all disassembled and laid out dampers from Torleifs works Kawasaki (KYB hand built), KYB series tillverkning, works KYB from Yamaha, Showa, production bike Bilstein, production car Bilstein, Koni, White Power from Holland (modded car Bilsteins) and maybe some others..
All laid out and everything measured, and examined and tested for strength---shock shaf into vise and a big long ring-nyckel ove one end and then BEND! Bilstein shaft was 10mm...production Öhlins were 14mm---which is several times stronger..

So no real secrets..

Much more important is the openness of the mind of whoever is in charge...Some "vet allt" and are compelled to have their way, some listen...and know that more is done better thru cooperation...
Tommi Has a relationahip with somebody , that's important because he has a very hard head and even engineers have egos--hell even machinists/fabricator guys (like me) have egos and thick heads..So relationship first, then they can make anything.

(My bossback then, Peter Strandh, also (like ever single person at Öhlins) was from Upplands-Väsby (and everybody was in UVMK) had the subcontract to make the automated welder to weld the bottom eyelet forging onto the shock tubes....so we were there many evenings when the prototype stage was going over to production. I still make suspension 40 years later..)

There are some users on Twitter stating that FIA has stated that the Yaris rear wing is illegal because it is not according to regulations 2017. Does anyone know more about this?

Toyota (Tommi) has said after 1st test that wings are not even close to final versions...

So for rounding up, you´re saying the brand doesn´t mean a lot. Only how the whole package is constructed and mounted/adjusted indoors own workshop (like Toyota in this case) by people knowing how to do. Right?
Like I tried to say as well.
Your swenglish is gorgeous btw!! :)
