This short steering horn is designed for high traction applications where your car is too edgy and you are looking for a slower steering feel.  It is ideal for Pan Car and larger flowing tracks where you do not need as much steering throw.  Due to the design of the shorter horn, you will only be able to achieve about 80% of the previous steering throw, so if you are using 85%+ Dual Rate, this is probably not the horn you want to use.
