Those won't fit. Any rim and tire that would work for the Tamiya F103 will also work on the Delphi car. Pro-Line used to make foams for that car, and they held up decently. Are you running with the guys at St. Mathias and MATC? You can also glue up your own foams if you can't find them. Blue front and green rear tires would work well, or a blue/orange front too. If you could find Tamiya foams, HBR medium fronts with f103 Kit rears were dialed. Also, you could use the F103 A-Compound rubber slicks. They are softer than the Duratrax tires and should hook up better.
