SDT bimetallic discs: European innovation for high-performance brakes

In the world of high-performance braking, every detail matters.
SDT perforated brake discs represent the perfect balance between technology, thermal efficiency, and durability—especially designed for those seeking maximum safety in sports or intensive driving. Today, we tell you everything about our new bimetallic discs: how they are manufactured, why they make a difference, and which models are already available in our range.
What is a bimetallic disc and what is it used for?
A bimetallic disc consists of two different materials assembled precisely:
- A high-strength aluminum center core (hat)
- A friction surface (outer ring) made from a cast alloy of carbon and silicon
The goal? To combine the best of both worlds:
✅ Weight reduction without compromising strength.
✅ Greater thermal dissipation, even during prolonged braking.
✅ More precise response on demanding sections.
This type of disc has become a standard in racing and high-performance vehicles, and now SDT makes it accessible to enthusiasts and professionals alike.
SDT manufacturing process
At SDT, we commit to 100% European production under strict quality controls. Our bimetallic discs are manufactured through the following processes:
- ? High-precision CNC machining to ensure exact tolerances.
- ? Thermal treatment of the friction ring to improve resistance to thermal fatigue.
- ? Floating assembly with stainless steel bolts allowing independent expansion, preventing warping.
- ? Individual dynamic balancing on each unit to guarantee performance in any condition.
Each disc is the result of real competition vehicle testing and demanding thermal simulations.
Thermal comparison vs. conventional discs
The main advantage of SDT bimetallic discs over conventional (solid or monoblock) discs is their optimized thermal management:
Characteristic | Conventional Disc | SDT Bimetallic Disc |
---|---|---|
Average weight (pair) | 12.5 kg | 9.8 kg |
Thermal dissipation | Medium | High |
Warping risk | High under intensive use | Low |
Stability during long brakes | Variable | Constant |
Lifespan in sports use | Medium | High |
Thanks to this innovation, SDT discs achieve less fatigue, greater precision, and better thermal recovery—especially important during track days or prepared vehicles.
Available compatibilities and models
Currently, we offer 4 references compatible with premium high-performance models:
- SO2370VF
- SO2375VF
- SO2380VF
- SO2381VF
These references suit braking systems with specific measurements and are oriented to sports and street vehicles with intensive use. (More models will be added soon to expand compatibility.)
If you have questions about compatibility with your vehicle, contact our technical team for personalized advice.
Why choose SDT perforated brake discs?
Besides their bimetallic design, SDT discs feature:
✅ Strategic perforations for better gas and water evacuation.
✅ Floating design that reduces stresses and improves pedal response.
✅ European manufacturing under ISO standards and testing in real conditions.
✅ Compatibility with sports pads like our S50+, RS55, or RS55.
Conclusion: maximum innovation for demanding drivers
SDT’s new perforated brake discs are designed to go a step further in performance. Whether for a track day, weekend sports use, or to mount on the front or rear of your high-performance vehicle, they are an investment in safety, durability, and precision.
