Are rear Emira OEM wheels really ET54mm??

[Porter]

Just as an idea, and a way to recover some of the cost... that whole set of wheels should be a perfect fitment on a V6 Emira. Any chance you could sell the complete setup (including TPMS, tires, etc) to another owner for what you've put into it, and re-order? It's super inconvenient, but if you're already having to re-do the rear wheels....

I’m in China and have better things to do than take a hit and deal with that shit. The Lotus specialist supplier that is also in China is better positioned to find a customer for some V6 spec wheels than I am.

Ok man, whatever you like. I was just trying to think through solutions since you've already mounted TPMS and tires on them.

It is actually marked, but it’s not exactly obvious. I looked yesterday and didn’t notice. Most information is stamped quite clearly, but wheel specs are stamped very lightly, can just about make out ET64.

Measured OEM rim width and hub to rim.
209-(291/2)=63.5mm by my measurement, but hub was tricky to measure exactly.

Apparently lots have been sold and nothing said. Must be ok then

Ich habe heute nachgeschaut, konnte aber keinen angegebenen ET-Wert finden. Als ich nachgeschaut habe, ist mir aufgefallen, dass etwas nicht stimmte, und ich habe versucht, herauszufinden, was das Problem sein könnte. Werde morgen ein Foto machen.

Dadurch werde ich lernen, den Informationen zu vertrauen, die überall im Internet, beim Anbieter und auch in diesem Forum zu finden sind.

Es ist tatsächlich markiert, aber es ist nicht ganz offensichtlich. Ich habe gestern nachgeschaut und es nicht bemerkt. Die meisten Informationen sind recht deutlich gestempelt, aber die Radspezifikationen sind sehr leicht gestempelt, man kann gerade noch ET64 erkennen.

Gemessene OEM-Felgenbreite und Nabe zu Felge.
209-(291/2)=63,5 mm nach meiner Messung, aber die Nabe war schwierig genau zu messen.

Anscheinend wurden Lose verkauft und nichts gesagt. Muss dann ok sein:weinen:

Ich habe leider jetzt auch ein Problem mit der ET. Bin davon ausgegangen, dass die I4 auch ET 54 hat und habe mir bei Aerie für Hinten 11x20 ET 45 bestellt. Versuche gerade Jason zu erreichen, ob man das noch ändern kann !!

I copied your specs, just another colour. Wasn’t aware yours is also a Turbo. Have your set already shipped?

 

[ital-corse]

Ich habe Ihre Angaben kopiert, nur eine andere Farbe. Ich wusste nicht, dass Ihr Set auch ein Turbo ist. Wurde Ihr Set bereits versendet?

Ja ist eine Turbo Emira.
Ich habe Jason gleich angeschrieben und gefragt ob die Felgen schon versendet sind. Habe noch keine Antwort bekommen.
Welche Maße haben Ihre Felgen?

I did same specs as you exactly. 9” on front, 11 on rear

 

[ital-corse]

Ich habe genau die gleichen Spezifikationen wie Sie gemacht. 9" vorne, 11" hinten

Welchen ET haben Sie gewählt?
Bei mir ist es vorne ET 51 mm und hinten ET 45 mm.

Yes, exactly the same. It pushes the fronts out 12mm and the rears 15mm (on a V6) on the outside face of the rim. However with ET64 instead of ET54, the rears are pushed out 25mm reference to standard wheels, which is too much. It looks silly and will rub.

Are the i4 wheels still a 10.5, with just the ET changing to 64? I ask as Aerie mentioned an 11" rear wheel in an email thread.

I4 wheels are still the same width as the V6, 8.5 front, 10.5 rear. However, I went wider and went 9 and 11. The factory offsets are ET57 front and ET64 rear.

I would consider that, but I want to use the OEM tires, and don't want any kind of stretched look, so I prefer to stay OEM for only that reason.

That’s fine, but if you run standard run OEM rim widths, you shouldn’t use my offset values.

I got the follow information regards the OEM wheels:
Front: 8.5x20 ET 57
Rear: 10.5x20 ET 54

is this correct?

I was running 12mm spacers, so that means an effective ET45 on front and ET42 on rear.


Spec’d new custom wheels based on the above, but new rears are poking out way more than they should. Fronts are about where they should be.

Checked the OEM wheels and got circa 295mm width and 210mm inside rim to hub. This comes out to the below:
210-(295/2)=62.5mm offset (not 54mm)

I didn’t have a suitable sized caliper to check the OEM and new wheels accurately today, but I’m pretty sure any errors in the above will be minimal.

Has anyone else actually measured the OEM wheels, or seen other data?

Please pardon my ignorance, but what is the advantage of using spacers (or any system) to move the wheels further apart than what the designing engineers deemed to be most suitable? Does it not put more load on the wheel bolt stubs, by transferring the load area out along the bolt thread away from the axle hub/bolting point? Is the structural integrity compromised in any way to gain a slightly wider wheel track?
