Race Winner - Todd Ulery's DTM Opel Calibra 

Short answer: it helps to isolate the body roll from the chassis roll. A little more detail: this decouples the moment of inertia of the body and the chassis, until the point when the head of the body screw contacts the top of the body post. It's important to note that, for this to work properly, the body needs to be resting on the outer edge of the chassis and not on the body posts. If a particular car has a body that rests on the body posts, and not on the edges of the chassis, then I don't think running the body loose helps at all, and probably makes the car worse. To help visualize the body's interaction with the chassis, take the body off of a car and put the chassis on the track. Now, try to make the chassis lift by lifting on the body post and pushing on the outside edge of the chassis. Pretty easy, right? Now try it again, but only pushing on the edge of the chassis. Much harder. By running the body loose, you're limiting its forces on the chassis to the latter scenario.

Todd designs all his own decals on the computer, and makes them into masks. So usually all the cars are “all paint.” The tires will touch the track on all four corners 😊

@@idwurks man I have been trying to make them I find it difficult to do!! If he could share that would go miles beyond appreciation 😆and I will do a test and tune I may have the height to high , thanks again

@@nflpicks4920 This car is all done with an airbrush and masking. I have a Silhouette Portrait 3 that I use to cut the masking. The masking vinyl that I use is Artool Ultra. If you're using water-based paint then Oramask 810 works equally well and is much cheaper. Re: Front tire height. Since this race was on plastic track, the car was setup with the tires just off the block (on a flat/zero recess block). Only about 0.010" off the block. On wood track, I would have the front tires touching the block.

@@toddulery Understand we primarily race on plastic tracks so I will see how it handles I’m coming over from HO so it’s a learning curve especially in the turns
