If they offer a thicker 2.0mm aluminum chassis, I'd probably run that and just adjust where I can to make up for the increased height. Unless you're Jacob Cruz, Ron Volker, etc most of us club racers probably won't realize the benefit before we hit something and tweak it. A tweaked thin chassis would hurt our lap times more than just running a thicker chassis that's more durable. I should have all my kits, parts and option parts later this week so will be building one of them for myself to race later this month on a decent sized outdoor asphalt track. So we shall see how the chassis holds up to my driving. Jackson Raceway here in Jackson, NJ has concrete curbs but they're smooth if you ride them right
