Proline 'Slide Lock' S4 Pre- Mount Vel. V2 White Wheels (2)

The Pro-Line 'Slide Lock' S4 Premounted Velocity V2 Wheels (Part No: PL9064-234) represent the high-grip, "special conditions" version of the Slide Lock racing tire. Featuring the S4 (Super Soft) compound, this setup is designed for 1/8 scale buggies competing on polished, hard-packed, or damp tracks where maximum mechanical adhesion is required to keep the car stable.

Key Features:

• S4 Super Soft Compound: This is Pro-Line’s softest "S" series rubber, engineered to provide maximum "stick" on surfaces that feel slippery or cold. The S4 compound allows the small lugs to conform to the micro-texture of the track surface.
• Slide Lock Tread Design: A unique pattern of small, densely packed hexagonal blocks. This design creates a massive surface area of rubber-to-track contact, specifically intended to reduce "sliding" during cornering and acceleration.
• Velocity V2 Dish Wheels: These white racing wheels feature an aerodynamic, debris-shedding profile. The V2 design is highly durable, with a reinforced 17mm hex area to withstand the stresses of pro-level racing.
• Closed-Cell Inserts: Equipped with high-performance closed-cell foam that provides consistent internal pressure, preventing the soft S4 rubber from "squishing" or deforming under heavy cornering loads.
• Ready-to-Race: Factory-mounted and glued, ensuring a balanced wheel and a professional-grade bond that won't fail during intense main events.

Racing Tip:

The Slide Lock S4 is your "secret weapon" for indoor clay or tracks that have been watered and are still "tacky." Because the lugs are so small and the rubber is so soft, they provide incredible forward bite. Pro-Tip: Be cautious using S4 on a dry, abrasive "blue-groove" track in the middle of a hot afternoon; the soft lugs may "overheat" and wear down quickly. These are best utilized in the final qualifiers or mains when the sun goes down and the track temperature drops.
