Since the new owner of my Spec3 doesn't fit in my "little guy" halo seat, it's for sale. It's a Sparco Circuit, purchased from OG Racing in the fall of 2013. It's seen 3 HPDEs and very limited street driving. The car was stored in the garage, so it's had very little exposure to UV. It's a darn nice seat and quite comfy when you get in and situated. I'm 5'5", 160 and it's snug on me. I can see folks taller and thinner still being comfortable, but I cannot overemphasize that this is a small seat. The stats on the seat are in the link from OG (Circuit I model):

I will be in Cary the weekend of 12/13 to sell my trailer to Stephen Westerfield, so I can certainly bring the seat down for the buyer and leave it with Stephen. If I have no interest, I'll take it with me to CA and use it in the next fun car.
I'll shoot a couple of pics of the seat and the date sticker this week and update the thread.
