I just bought this 1989 C4 convertible with red Fittipaldi rims and very old tires which are being replaced by Firestone Firehawk Indy 500 summer tires. I have never seen these rims before and cannot find them anywhere on the internet. I do not know how long they have been on the car and cannot find out when they were made. Some people do not like the red paint, but I think it looks great on this bright red car.
