The harder they struggled the tighter they became wedged. Higher speeds and tighter turns require greater lean angles. These changes combined with tighter tolerances result in greater potential accuracy. It also improves the surface finish and holds tighter tolerances. Higher the rigidity tighter is the constraints. V8s were progressively detuned as production wore on in line with tighter emission standards. The two were then kept under much tighter security. The regime felt the need for tighter control. A loose measurement can, and often do, vary from the tighter measurement. A chiseled brush permits the painter to cut into tighter corners and paint more precisely. The TORRO scale has 12 levels, which cover a broader range with tighter graduations. These attacks resulted in even tighter security precautions. Supersport regulations are much tighter than Superbikes. The more precise the measurement, the tighter the range. The new material was tighter and more focused than the demos.
