For RA64? Nah, AFAIK such a thing doesn't exist; I see an option for the Supra MA61 though, which matches the part number you included. Some folks have adapted the MX73 BC BR coilovers with S13 front tophats to RA65s, but the spring rates are really high (10k/8k). I built my own short stroke coilovers (see link in signature) and run 8k/6k springs. I'm exploring options with a new local supplier to cover all of the options (Celica ST/GT and Celica GT-S/Supra) and get proper quality coilovers.
