Just use altavista to see what the blanks are and then fill them in on the Japanese page.Its pretty simple,and you will get e-mails about all the new Tamiya stuff before most other places. If your computer dosent susport Japanese just download the Japanese option from windows its free.
Our info at work here is that the Mini Cooper S is the good old M03L chassis,doesnt say anyting about wheels.Just an updated body. We dont have pictures yet just the order form with a list of the new stuff,and very short discriptions.
