On the street, bedding happens naturally in the first 100-200 miles of urban use but for those drivers wishing to arrive at the track with new pads and enjoy their day, our current suggestion is to use the Bluestuff formulation for track day driving both front and rear.\u003c\/p\u003e\n\u003cp\u003eBecause of its huge heat range, the applications where EBC Yellowstuff will deliver benefits range from fastest street use on higher horsepower cars on most street-based cars and even as a brake upgrade on Trucks and SUV. Yellowstuff is especially appreciated on Trucks for towing and heavy loads and where wheel and tire oversize upgrades have been fitted. In trackday\/drift\/hillclimb races where earlier Yellow blends were suggested, although track capable, is no longer recommended for track use on most cars due to its long bed-in process.

It is also the choice of 90% of the Mazda MX5 Miata competitors in the UK race series, used in drifting and on kit cars. EBC Yellowstuff pads are also used on the UK Silverstone Race Track Drivers experience cars because of their high performance and longevity. Yellowstuff also claimed a win in the Targa rally and for two years running in the Brazil Mitsubishi off Road Team Desert Challenge.\u003c\/p\u003e\n\u003cp\u003eThe majority of UK Police forces use and love EBC Yellowstuff brake pads.
