      Please add the Mercedes C Klasse AMG car to the eligible list.  I own one now.

      The draft rules on the splash page are just a placeholder. At least I hope so.

      So, what is the status of these rules? I have heard that they are a placeholder and that were allowed to do lots more than in these rules. I’m working on my rear wheels and checked the rules to be surprised by, “Only the stock Slot.it short hub aluminum 15.8 x 8.2 wheels allowed on the rear,” since I was under the impression this was open along with any tire choice (the rules say Slot.it only). Can we get this stuff clarified so I can get my car completed, please. 🙂
