Old post I know, but this info is like pulling teeth to find. I weighed everything I had, which includes the 2004 MY OEM 18's and the NISMO LMGT4 Rays in 19", with and w/o tires.
The 19" OEM Rays are closer to 21/22. NISMO LMGT4 Rays which are a little wider weight 21/22, also. The LMGT4 Rays in 18's are 18.3 lbs, darn light. So 18 and change for these Rays is probably right on the money.
As for 2003.5 Coupe wheels those are the same as my 2004 OEM wheels, they are a porky 24/25 lb in 18". With the original tires mounted there was a 2 lb difference front to rear, 42 lbs and 44 lbs, margin of error though about 1-2 lbs with the tires on. I weighed them 3 times on a pretty basic scale and averaged the numbers (with tires, the OEM Michies).
24 lbs is pretty heavy IMHO for a OEM Sport Package 18" wheel, they did much better with the next gen wheels - except they should have made the 19" rears 9-9.5" so you could more easily mount a little bigger tires. Keeping the 245/45/18 rear on a 8" or 8.5" was a mistake IMHO.
3 lbs of rotating weight...times four corners, it really makes a noticeable diff.
