Mmmmm that's not totally true. nothing there had a chassis,but the upper cars were either DSE equipped or Ridetech cars. they are as you mentioned very high dollar cars if you went to build one.
Ok, I see what you mean by full chassis. You're talking about a full Swartz type chassis, I assume?
To make more clear, I just meant most top cars don't have any stock suspension chassis points, suspension types. I'm pretty sure the DSE cars have a completely fabbed front sub frame. So maybe not a full frame, but half of one. And the rear is 100% fabbed too and it's connected by fabbed frame connectors. Essentially making it a full frame.
