www.aaarims.com or the 3si.org parts forsale section. With AAA Rims you don't have to worry about buying peeling or bent rims. Salvage yard pickings are getting slim.
They currently list the 95 3000GT chrome five spoke at $455 a piece or about $1780 for a set of four.
You can also get Stealth rims with a chrome option.
I have been considering buying replacements for my two peeling rims since rechroming costs more than OEM replacements. AAA is the place I would get my replacements from.
You have to beware of potholes. When the rim bends the chrome does not. My rims were spotless when I bought the car but pot holes, curb rash and clip on wheel weights have done some damage.
The rims usually don't include the center caps.
I ordered a set of center caps and snap rings (about $70) from Kuettner after I replaced my tires. I bought them using part numbers from CAPS with a Spyder VIN but the caps were silver painted not plastic chromed. Since the part was special ordered and I specified the part number they refused to work with me to solve my problem. Chrome paint only made them look worse.
