The only Subaru model to get the OEM 28111SA081 wheels was the Forester STI.
The only S11 JDM model Forester to get the OEM 28821SA060/61 STI centre caps was the Cross Sport.

A faux carbon weave black finish?

In the US they were fitted to the 06/07 Forester Sport

Although some websites list them for the 06/07 Impreza WRX STI Forester ??
No idea if these centre caps will fit the STI wheels.

No UK/EU Imprezas got STI caps

Not sure if the 08> WRXSTI caps (28821FE140/141) would fit as they appear to be 55mm dia

 

Thanks Don,

That's reallly helpful, at least I have a part number to work on now. Difficult to find anyone showing the diameter though.

I have the 55mm center caps (28821FE140/141) on my Legacy's STi wheels, tried one on the Forester but too small, they definitely need to be 60mm.

 

ST28811ST000 looks like it might fit, diameter is 59mm. But too expensive to buy a set just to find they don't.

looks like i found the same pic. but after measuring the stock center caps from the same wheels, I think they might just work. take a look at the pictures from the rakuten link

 

I machined some caps up myself, and put some gel covers on them!

 

Judging by the cost of the OEM items, you could make a few quid selling them!

 

Thanks for the suggestion - if anyone needs any I don't mind having a go.

 

@ferretboy I'll be taking my wheels off in a couple of weeks to refit my Brembos when they come back from being refurbished so will pop a centre cap out and measure it properly against the Rakuten info. It looks like they are pretty close. I'll let you know.

 

@ PacoJones I measured and took a chance and ordered them from Japanparts.com and received them today.
1. Japanparts Number : 1005G-017-040
Parts Name : ENKEI WHEEL CENTER CAP
Parts Maker : STI

They fit pretty snugly , but if there are crooks out there they might try to steal them as you can pry them off if you try. Here's a pic of them on my wheel with packaging and sku number along with pics of wheels on the car from afar. Next subtle mods are Bilstein struts and STI pinks for OEM plus feel

 

@ferretboy

Excellent, thanks for letting me know, I've ordered some as well (5 so I have a spare for when one gets lost, stolen, etc).

Have to say those SG STi wheels look pretty good on the SF Forester. Nice job.

 

@ferretboy

STi centre caps arrived yesterday, put them on yesterday afternoon and they look good to me. And they are cheaper than buying used versions of the original centre caps for these wheels. Happy days. Thanks!
