Proline 'Blockade' S4 Premount Velocity V2 White Wheels (2)

The Pro-Line 'Blockade' S4 Premounted Velocity V2 Wheels (Part No: PL9039-234) are the specialized high-grip variant of the famous Blockade racing tire. This version features the S4 (Super Soft) compound, designed specifically for cold weather racing or extremely slick, low-traction track surfaces where "mechanical bite" is the only way to find traction.

Key Features:

• S4 Super Soft Compound: This is Pro-Line's softest "S" series rubber. It is engineered to stay pliable in cold temperatures and provide maximum "stick" on polished or damp surfaces where firmer tires would simply slide.
• Versatile Blockade Tread: The staggered, large-lug design provides a wide footprint and excellent forward bite. The internal siping allows the lugs to flex and find grip even on "marbly" or dusty tracks.
• Velocity V2 Dish Wheels: These white wheels are designed with an aerodynamic dish profile that minimizes debris buildup and protects the wheel nuts. The V2 design is reinforced for the extreme stresses of 1/8 scale racing.
• Closed-Cell Inserts: Pre-installed with high-density closed-cell foam that doesn't "fold" under the soft S4 rubber, ensuring the tire maintains its shape through high-speed corners.
• Factory Glued: Professionally assembled to ensure a perfect, balanced bond, allowing you to go from the package to the track in seconds.

Racing Tip:

The S4 compound is a specialized tool. While it offers incredible grip, it will wear much faster than S2 or S3 compounds if used on high-temperature, abrasive "blue-groove" tracks. Pro-Tip: Save these for the morning practice sessions when the track is still damp/cold, or for "slick" indoor tracks where you need every bit of help to keep the rear end from stepping out.
