This is the regular Aeromotions R Splitter.
It sells for $1500 new.
My GT-R partly impacted a curb and gashed this thing, but it held up mostly like it was designed. These things don't shatter, they scar, meaning material will get ripped out but the structure stays in tact. The damage was minor, but you will have to re-rivet the one piece. I took this off after having the front bumper replaced and the body shop lost all the hardware, so that has to be replaced. I was quoted $95 a few years ago.
It's still in good shape. You can see the scar on it but it isn't that noticeable and should affect functionality.
On the track at speed my front end was planted a lot better than stock. It worked well even without a rear wing.
Asking $500 shipped obo. Will ship in continental USA. Payment via Paypal, Venmo or Zelle.
