I guess people are witholding their opinions mostly because it just is a matter of opinion.

The wheels will fit, and it's just a matter of opinion whether you want 17", whether you want to put DC5 wheels on your DC2 ITR (some would consider that anathema), and even whether there's any point in painting them.

I mean, after all, a lot of us have white Kosei as spares or track wheels, anyway.

Now that I think about it, I'll have a set of white SSR Type C's and a set of white Kosei for my black ITR...and I don't worry about it one bit.
