Cyrul eXcelerate - Foam Inserts - Double Stuff - Medium

This product is a medium double-stuff foam insert designed for 2.2/3.0 short-course style tires used in no-prep RC drag racing. The “Double Stuff” design uses a larger outer diameter foam profile that helps fill the tire carcass more fully, reducing tire deformation (“wadding”) during hard launches. This improves consistency off the line and can also help maintain better top-end stability and speed. The medium firmness provides a balanced setup for high-grip track conditions where both support and controlled compliance are needed.

Features:

• Medium-density Double Stuff foam for balanced support and grip
• Designed for ultra-sticky no-prep drag racing surfaces
• Larger outer diameter helps prevent tire “wadding” at launch
• Improves straight-line stability and top-end consistency
• Fits 2.2/3.0 SC-style drag racing wheels and tires
• Available in multiple widths for tuning setup balance
