Generally, 15" wheels will not clear the front brake calipers on a C20 or K20. You can usually grind a small amount off the calipers and gain enough clearance for steel wheels to fit, but those aluminum wheels may be too thick. Unless someone who has actually done it chimes in, you may need to test fit them in order to know for sure. If they almost fit, you can get away with grinding the calipers.
