Comparison
The main difference between the F18 and F23 gearboxes is the number of forward gears. The F18 has four gears, while the F23 has five. This gives the F23 a wider range of gear ratios, which can be useful for both performance driving and fuel economy.
The F23 gearbox is also generally considered to be more durable than the F18 gearbox. This is due to a number of factors, including the use of stronger materials and improved design.
As a result of these differences, the F23 gearbox is typically more expensive than the F18 gearbox. However, the increased durability and wider range of gear ratios may make the F23 gearbox a worthwhile investment for some drivers.
