I found these:

I wonder if they are available in the U.S.

I don't know who makes them.

rota makes a pff-7 replica, I believe it's called the sdr.

your right. but they don't come in 18".

And the SDRs are replicas for the GC-07s technically.

yea, they're actually more similar to gc-07's than pff-7

Doesn't really seem too cost effective. That site says £850.00 for a set of 4 w/ tires, which is about $1,610. You can get a real set of PFF-7's for $1,200 shipped, along with tires for roughly the same cost as the replicas. I'm sure the crappy exchange rates attribute to the high cost though, and as mentioned before the only other replica of the PFF-7 that I know of is the Rota SDR.

If you really have your heart set on 18in PFF-7's/replicas, it'd probably be easier to look for a used set, or just save up the extra cash for a brand-new set.
