... the NT03+M
They're not really "new", as I've seen them on JGTC cars from like 3 years ago... but I just found out what wheels the are, and that they've got 'em in Subaru fitments.
And Matt, the dual valve isn't for running an inner liner, it's so you can put a gauge on one valve and add/remove pressure from the other.
They're a little heavy in the 17x8 5x100 +48 size I'd use (18.3lbs), but if they're not too expensive, I think these will be my track rims!
