Anyone around that may know the manufacturer of these mounts? Seller said they were poly... But these feel like plastic the bolts are also offset.

supposedly came of a S5 JDM motor,

 

Probably FOMOCO for the Mustang in your profile.

 

nope that already has poly mounts. and they put a manufacture stamp on everything.

 

Apparently you got my point....since this is an RX7 forum, and since you're posting a question presumably about mounts that came off of a RX7, it might help to know what series RX7. It would also help in the future for you to add that information into your signature, or at the very least edit your profile to include it.
Now that you're edited your initial post to include that they came off a S5, I think urethane is a type of plastic with varying durometers (scale of hardness). I can't tell the manufacturer off-hand. A lot of aftermarket sources and probably even more in JDM land. Maybe someone more familiar with the FC will have a go. But the fact that they are apparently pretty hard, but with off-set bolts suggest they've been engineered to control movement well, but NOT transmit NVH. Which is a good thing.

 

thanks. ive been looking all over, but cant seem to find any blue mounts for an FC anywhere.

 

well thanks to google translate i found this...
???????????????????? / ??????????(FD3S)

 

looks like they are for an FD and lower the car 5 or 10mm depending on the mount ... so these im guessing are the 10mm drop. why?

 

The only reason I can think of off-hand would be to compensate for the thickness of an oil pan brace. Most braces are about 3/16" thick. And since the engine mount arm bolts to it, it would raise the engine otherwise.

BTW, your post count is high enough now. You could try posting in the 2nd Gen. section and might get a wider audience.
