I got a set of wheels off a Porsche 928S4. These are not factory wheels they are Japanese 3 piece wheels. I can't find the name of the manufacturer only casting marks "Made in Japan", "FIRST", "E-206, and some other marking but they don't reveal much.
I would appreciate if some one in the forum could identify them.
Thank You
Rh/speedlines.
In reply to mndsm :
Yep that is them! Thank you for helping me identify them. Is RH the manufacturers name or is that just the initials?
Not RH, they are BW Racing. They use Fikse/Kinesis wheel halfs.
edit: I had them on my 928 as well, they seem to be a popular addition to 928s. The Speedline above is worth $3k, the BW are hard to sell for some reason and go for 8/900.

Honestly, not sure. I did about 30 seconds of googling.
After carefully looking at the picture I noticed something different, the valve stems. The valve stems on my wheels are on the back rim with an L shaped extender that comes out to the front. The rim has a cut for the valve stem to rest on.
Mine have some similarity to the ones Chandler posted. When viewed from the back the rim is serrated the bolts go through holes on the teeth.
Good golly Molly but I do seem to remember in the 90s that rivet look was the E36 M3. At least in the UK.

I guarantee Chandler has it right. He's far better at the wheel game than i am.
