Differential swap
Reason being : the original 280C tire size being 185/78-14's have been replaced with 245/60-14's and because of the smaller diameter of the tires the engines RPM's are much higher . I love the look of the wider tires on all fours and its stance being lower to the ground so I have to change the rear end gears to keep decent mileage and RPM's back to normal.......
