Hello, I'm going to start build a Trumpeter E-100 soon, and looking at the various extras I could get I found a workable suspension kit from Atelier Infinite, but I couldn't really find much info on it, looking at other suspension from the same brand it appears the kit consists of suspension arms, springs, and some other resin pieces that go inside the model. Anyone knows anything more?

Piggybacking another question, since it's somewhat related, I'm thinking, since I also got a working track kit, of using small 4*7*2 mm bearings (temporary measures, once the model arrives I'll get the right ones) to also make the wheels rotate. A quick scan makes me think I can get 20, so for all roadwheels + idles&sprocket, for less than 5 euro. How crazy/genius/feasible is this idea?
