PAGID RST 1 Racing Brake Pad (Shape 4346) S4346T01001
Built for outright stopping power and control on track. RST 1 is a high-friction racing compound with a very strong initial bite, quick response, and stable performance at high temperatures. Ideal for sprint racing, tarmac rally, time attack, and qualifying laps where every stop counts.
Race use only – not recommended for road use. Expect higher noise, dust, and disc wear than milder compounds.
Why choose RST 1
– Very high initial bite for shorter braking distances
– Consistent pedal feel under repeated hard stops
– Works from moderate temps, excels when hot
– Suits aggressive driving on slicks or semi-slicks
Best suited to
– Sprint races, hillclimb, tarmac rally stages
– Short- to medium-length track sessions
– Drivers wanting maximum bite and rapid deceleration over pad longevity
Fitment guidance
Pad Shape 4346 is used in selected motorsport calipers and big brake kits. It may appear across popular track builds from brands like VW, Audi, BMW, and others depending on the caliper kit. Use our vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details. If you run a race caliper, compare the pad outline to your current pads.
Bed-in advice
Heat cycle the pads with several medium-pressure stops to build an even transfer layer. Avoid holding the car stationary with hot brakes. Increase load once a consistent pedal is felt.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
