3.Rear wheel modification idea (the front wheel shall be determined first, and then the corresponding ratio shall be made)

Front four pistons: 9200 8530 9540 rear two pistons: 5317

Front six pistons: 9040 rear four pistons: 9202 / 7609

Front six pistons: 8520 8521 8522 rear four pistons: 8530 / 8540 / 8560

Front six pistons: 9560 9561 9562 rear four pistons: 9541 / 9542

The collocation needs to follow the first six rear four front four rear two front big four rear small four (the car power needs to be distributed, and so does the braking force)
