Does anyone know who makes the factory wheels for the '05 S2000?

There is an unusual stamp in the casting that I have seen on other wheels, but I can't quite make out what it is.

Thanks

 

Dunno about the 04-05 wheels, but they may be the same as the AP1 wheels. Enkei makes the AP1 rims.

 

that unusual symbol is the "3E" certification.

basically, it means that the wheel meets certain strength and balance characteristics. Just about every OEM will use "3E" rims.

Many aftermarket "dubs" are not 3E certified. That's why they often ride like crap.
