Spec-R Droop gauge set & Support blocks
New from Spec-R design is this precision droop gauge set and height adjustable support blocks for 1/10 cars. The droop gauge is made from CNC machined aluminium and features a measuring range from 29.5mm to 33.6mm between the set up board and drive axle. When you select the +0.5mm support blocks, it can provide the odd number data to set up the cars. Measuring from the height of the drive axles ensures that there will be no interference from the plastic parts.
