In the universe of motorsport and sports driving, the braking system is a decisive factor. The evolution of racing brake pad compounds has allowed brands like SDT Brakes to develop specific solutions for each type of use, vehicle, and requirement. The new RS55 brake pads represent an ideal intermediate step between options for sporty street driving and more extreme competition compounds.

A new standard for the demanding driver
The RS55 are semi-metallic brake pads formulated specifically to deliver outstanding performance in:

• Track days and sprint circuits
• Rally with lightweight cars
• Rear axle mounting on non-lightweight competition vehicles
• Off-road vehicles in raids and high-performance buggies

Their development is based on real testing on track, focusing on pedal progression, thermal stability, and consistent friction over a wide temperature range.

Technical features of the RS55 compound
RS55 are the result of a carefully designed formulation by the SDT Brakes technical team to meet competition demands, without compromising disc life and with minimal noise, unlike more aggressive compounds.

• Compound: semi-metallic organic
• Operating temperature: from 0 °C to 700 °C
• Maximum friction coefficient: 0.51μ
• Exclusive use in competition (not street homologated)
• Perfect for OEM or racing caliper systems

This balance allows amateur or semi-professional drivers to have a pad that is resistant, safe, and highly thermally consistent, even in extreme conditions.

Recommended applications
RS55 brake pads are designed for very specific applications where performance is needed without reaching the extremes of compounds like RR80:

• Occasional track days with modified or sports cars
• Closed-stage sections in rally or hill climb competitions
• Rear mounting on powerful vehicles with the main brake on the front axle
• Sprint races, slalom, rally sprint
• Buggies and raids, where thermal dissipation is critical

Where do the RS55 fit within SDT’s range?

The RS55 is conceived as a perfect intermediate option for those looking to upgrade from street pads without yet entering a fully competitive environment.

Installation and maintenance tips

• Verify compatibility with the disc, ideally new or machined.
• Perform proper bedding-in (6–8 stops from 100 to 80 km/h smoothly), repeating the process multiple times by increasing braking force from less to more. Then allow cooling.
• Use DOT 4 Racing brake fluid with a high boiling point.
• Do not mix compounds on different axles unless technically recommended.
• Inspect the hydraulic system and ensure proper functioning of the calipers.

Conclusion
SDT Brakes RS55 brake pads are a safe choice for drivers seeking to improve their track or stage performance without compromising control or progressive brake feel. If you're looking for a balance of performance, thermal control, and competitive versatility, this is your option.
