YELLOWSTUFF
Yellowstuff ⁃ A first in a new range of 'Hybrid' materials that can be safely and legally used on worlds roads being R90 approved UK are a high friction upgrade pad for all fast street use
Yellowstuff has been the flagship pad by EBC for over a decade and gives instant brake response, great feel and modulations with silk-smooth noise free braking and was also improved in 2021 to be copper free and conform to all new legislations for the environment and our pads are fully shimmed chamfered and slotted .
Yellow arrives with pad surface Brake-in coating to accelerate pad bedding after install.
- 0.48 stable friction once bedded
- Strong initial bite ,work from cold
- Zero rotor damage
- Short to medium race lifetime
- Copper free for ECO compliance
✔ R90 Approved
With a stable friction coefficient of 0.48μ right up to race temperatures of 450℃,Yellowstuff is a very popular pad amongst kit car drivers and lighter race cars having clinched the MX5 race series. Although heat scorched, the compound does require careful bedding in before race use,
If planning track use we recommend using the pad for a period on the street to pre bed before making a track excursion. If you require faster track bedding also consider our new Bluestuff R 90 approved compound which beds in faster.
BLUESTUFF
A great all round sport and race pad, revised to a new improved formula in 2021 for faster bed-in.
Bluestuff material exhibits a 0.52μ stable friction once bedded stable up to a slightly higher 550℃/1000℉ than its sister compound yellow but with the benefit of 30% longer life than yellow.
Blue has been a trackday favourite for years and is the spec pad for the BMW 318i Cup series throughout Europe.New formula is copper free to conform to upcoming environmental legislations
- 0.52μ stable friction once bedded
- Strong initial bite ,work from cold
- Zero rotor damage
- Copper free for ECO compliance
- Excellent upgrade pad for SUV and armored vehicles in street use
✔ R90 Approved
Pads do require careful bedding in before track use.
Bluestuff also has good bite from cold and is an Aramid fibre base offering reduced rotor wear and has been popular with Trackday drivers due to its longer wear life than Yellowstuff, it's stablemate.
RP-1
EBC Racing's RP‑1 compound is an ultra‑high performance track and race pad designed for high performance vehicles driven hard on track. RP‑1 has a very stable friction coefficient of 0.45μ up to and beyond 750℃, making it an excellent performer for even the most demanding vehicle applications.
Due to its relatively high friction coefficient, RP‑1 is not Reg 90 homologated for road use within Europe and is therefore illegal for use on the public road. Unlike some other race pads on the market, RP‑1 offers a usable cold friction of 0.35μ below 100℃ meaning it can be safely used as a road pad for non‑European markets where Reg 90 homologation is not mandatory. At 100℃ the friction gently climbs to 0.45μ and stays there up to and beyond the designed upper working temperature range of 750℃.
RP‑1 boasts good pad life but the unique characteristic of RP‑1 is that it boasts exceptionally low disc wear, lower than virtually all other competitor race materials tested by EBC Racing. RP‑1 has a progressive pedal feel with unrivalled modulation. RP‑1 does not have the snatchy pedal feel or high levels of noise often associated with other race pads on the market.
Compared to EBC Racing's other track pad RP‑X, RP‑1 has a 25% reduction in friction coefficient across its working temperature range making RP‑1 the more suitable choice for light‑medium weight cars, cars with non EBC Big Brake Kits fitted, or vehicles with no ABS. For heavy or inherently under‑servoed vehicles which suit a very aggressive pad, EBC Racing's other track material RP‑X may be preferable.
RP-X
EBC Racings' RP‑X compound is an ultra‑high performance track and race pad designed for performance vehicles driven hard on track and for dedicated race cars. RP‑X has a very stable friction coefficient of 0.55μ up to and beyond 850℃, making it an excellent performer for even the most demanding vehicle applications.
RP‑X also has a high friction level from cold, requiring no warmup to achieve maximum braking effect which makes this material well suited for sprint race and hill climb events. Although RP‑X is not R90 homologated for use on the public roads in EU member states, the fact this material possesses excellent cold performance means RP‑X can be safely used for driving to/from motorsport events (where local laws permit).
EBC Racing does however emphasise that RP‑X has been developed for peak on‑track performance, meaning higher levels of brake dust and brake noise should be expected. RP‑X has comparable disc wear to many other popular track/race materials, however RP‑X disc wear is considerably greater than EBC Racing's other track pad RP‑1 which results in high levels of brake dust.
Compared to RP‑1, RP‑X has a 25% increase in friction coefficient across its working temperature range with a much more 'positive' initial bite. This characteristic potentially makes RP‑X more suitable on heavy or inherently under‑servoed vehicles. For light‑medium weight vehicles, cars with non EBC Big Brake Kits fitted, or vehicles with no ABS, the less fierce nature of EBC Racing's other track material RP‑1 may be preferable.
