Is the HRE 440R series too 'square' for the round lines of the SC? I was all ready to wait for the 549R in 19x9 and 19x10, but I just have a thing for the 6 spoke look... problem is, the SC doesn't have a straight line in the styling. Could this actually compliment the soft lines of the car, or is it harsh and 'unclassy?'

Check them out on Craig's Skyline, 19x10, 3" lip, brushed center & polished lip:

 

Personally, I think the 54xR's compliment the SC better than the 44xR's for the very reason you listed (the SC's round lines)...

Man I love R34 Skylines!

 

Those are beautiful rims. I would think they'd look nice on an SC. If I could afford it, I'd get those rims for my car...
