ICAR's off-road vehicle wheel hub modification: The original vehicle has 18-inch wheels, which can be modified to 18-inch ones. When modifying the wheel hub, it is important to note that the ET (offset) of the modified wheel hub does not necessarily have to be exactly the same as that of the original vehicle. The original vehicle has relatively large, upright wheels, and we usually set the ET to ET18, which improves the modified performance and enhances the vehicle's balance, making it suitable for off-road use. Many car owners often assume that the wheel hub modification should be done according to the original vehicle's ET. In fact, such modifications are relatively rare. The wheels we modify generally have an ET of 0 to 30, and some even 40. Generally speaking, for ICAR, setting the ET to 18 for 18-inch wheels is sufficient. For the modified wheel hub of the Scorpion A723, we use ET18. The width of the wheel hub is 8.5J, the PCD (pitch circle diameter) is 5×108, and the center hole is 60.1. This modification effect is very good-looking. Please enjoy the following actual installation picture
