I've talked to Mr. Hara, chief designer of TB EVO III, and he told me that it is a translation failure in the setup sheet. the first "rebound stroke" means dropp and the second "rebound stroke" means wheel spacer. As you can see the japanese signs are different, so they simply made a translation failure.
BTW:
TB EVO III had big succes in Germany at the German Indoor Nats!!!!
Place 1 and 2 in Touring Car Stock (Winner Bernhard Bopp)
Place 1, 4, 8, 10, 12 in Touring Car Modified (Winner Marc Rheinard)
As soon as possible i will post some pics of Germany's EVO III.
