Race spec Cup 255s'

I’ve noticed that there are a couple of race spec Cup 255s up for sale on Pistonheads at the moment. Has their eligibilty to race changed, or is it just a coincedence?

One belongs to a friend of mine and I confirm it is a coincidence. Bit more detail on that one (in a good way) not listed in the ad so if he doesn’t update it and you’re interested please shout.

Oops his one isnt on PH yet, it’s on racecarsdirect.
