The firm throttle spring is an easy-to-install accessory for your Asetek SimSports® Invicta™ pedals. The throttle spring is harder than the one originally included and allows you to have a firmer sensation and even better throttle control. It gives you a better feel when racing, higher resistance and makes it possible to apply more pressure to the throttle, which gives you an even more realistic racing experience. 

The spring is already included in the Forte® pedals throttle by default, but the firm throttle spring can be used as a replacement or spare part.  

One spring and the compatible pivot base is included in the box.
