Tempest2000...
I'm not sure if they will be aluminum or plastic.. The plastic ones I've tried were very sticky..

Fatdoggy...
The initial kits my have locknut retaining front wheel system, but they may change to something new and innovative!!

I'm not sure on a release date, there maybe a small lot of cars made to see what interest there will be. Jason would be the person to direct the release date questions, cost, pre-order info... I'm more involved with chassis set-ups, designing, and testing.
