Most definitely Hyper Meeting at Tsukuba Circuit. This is a great photo.
From front to back: JUN GRB STi, C-SER GRB STi, Bozz Speed Evo IX, Original Runduce Evo X, Original Runduce GRB STi, Car Station Marche GRB STi, Prova GRB STi, Zero/Sports CZS Type-Z Impreza, Sunline Racing Evo X.
I had a hard time figuring out that last car. I had seen the front bumper a few times, but couldn’t remember who made it. After some searching this morning, I discovered it’s the Syms GRB STi. Still though, 9 out of 10 ain’t bad!
