Via de diverse online shops is makkelijk te komen aan Pagid RS4-2 en RS14 blokken voor de Speedster. Als ik echter de informatie van Pagid zelf lees zou het RS5 blok wel eens zeer interessant kunnen zijn voor op de Speedster ...
RS4-2
RS14RS 4-2 (blue) Carbon Based
Few brake friction compounds are as highly
regarded as PAGID RS4-2 (known by many as
'PAGID Blue'). Originally developed in the late
1980's RS4-2 remains our biggest selling and most
versatile friction compound.
Technically, RS4-2 is a carbon based compound
with a medium friction level. It has an excellent
low temperature response, remains very stable
over a wide temperature range, and can withstand
constant temperatures up to 600°C.
RS4-2 is a very user-friendly compound with
excellent modulation and 'feel'. Drivers report excellent pedal-feel that gives confidence in
extreme braking situations. With its optimum blend of performance characteristics RS4-2 is
widely used across many forms of Motorsport from single seaters (Formula 3), through sports
car racing (Britcar), to Group N rallying on gravel and wet tarmac surfaces.
Increasingly, it is the preferred choice of brake friction for competitors in both historic rallying
and circuit racing. Subject to the requirement of Regulation EC90* it is also widely fitted as an
upgrade material for road cars.
Lower Disc Wear Another significant advantage of RS4-2, in comparison to many competitor
products, is its relatively low wear rate on the brake discs. Inferior pads may appear to work
well for a short period, but the wear rate of the pads and the brake discs can be very high.
Over the course of a season the PAGID RS4-2 product will often show not only a performance
advantage but may also save you £££'s when the replacement cost of pads and discs is
calculated. PAGID RS4-2 is available in over 100 different pad shapes covering most of the
popular racing calipers and many high performance road car applications.

RS5RS-14 (black) Ceramic Based
RS14 is our most popular ceramic based
friction material. Compared to RS4-2 this
compound offers a good increase in initial bite
and average torque, it has very good
modulation characteristics and offers good
control against wheel lock at all temperatures.
While showing a reduction in pad wear,
particularly at high temperatures it is still very
easy in terms of disc wear and shows a
reduction in surface stress fractures. RS14
will also tolerate much higher working disc
temperatures than RS4-2 extending further
the fade resistance.
RS14 is also used as an OEM material and
supplied as an up-graded track day pad by Lotus Motorsport department. It has been shown to
exhibit the most suitable level of braking force, control and modulation on popular track day
cars such as Lotus Elise and Caterham. Offering consistent levels of performance and a much
longer life than more inferior competitors products, without excessive disc wear while offering
the driver supreme confidence.
Outside the track day environment RS14 has also shown success in short to medium distance
circuit racing as well as gravel and tarmac rallying. RS14 offer very low heat conductivity
which allows less thermal transfer from disc through pad, thus resulting in lower caliper and
brake fluid temperatures which can have a critical effect on ultimate brake performance.
RS14 has seen good levels of success at many levels of Motorsport, from front applications on
front wheel drive touring cars, front and rear applications on 2 and 4 wheel drive rally cars, as
well as front and rear applications on GT and sports racing cars.

New for 2006 RS5 is the latest
development from the engineers
at PAGID, the initial design
criteria was for a material
specific for F3. However initial
feedback shows that this
compound is a great all rounder.
RS5 is a ceramic based friction
material with a medium level of
friction and smooth strong initial bite
giving instant response. RS5 offers
the most consistent level of friction of
all PAGID compounds, making it
much easier to brake very hard and
still having complete control over the
braking event. This allows the ability to brake very late into the corner with confidence, we
have seen 10 meters later than our major competitor’s product with no issue of wheel lock.
While still in prototype stage in mid 2005 test sets were issued to a major F3 team, with no
prior testing the pads were installed into 2 cars, one of these cars qualified on pole for both
races and took lights to flag victories.
This compound displays exceptional control, a higher average friction level than RS4-2 and an
increased operating temperature and increased pad life at higher temperatures.
Currently only available in a limited number of pad shapes, but this will increase in the near
future.

Wie kan me trouwens het verschil tussen carbon en ceramic based pads uitleggen, met name in combinatie met de soort remschijf?
En natuurlijk commentaar / advies! Ik ben eigenlijk geen circuitrijder, maar soms kan het op de openbare weg lekker vlot gaan
Zo langzamerhand heb ik wel genoeg van (het gebrek aan) de huidige stopkracht van mijn Speedster. Ter info, mijn Leon staat binnen 36 meter stil vanaf 100km/h, mijn Speedster heeft daar minimaal (!) 41 meter voor nodig.
Bijgevoegd heb ik nog even wat data uit de PerformanceBox. Vanaf 170km/h staat mijn Leon na 107 meter stil, de Speedster rijdt dan nog ruim 78 km/h
en staat pas na 134 meter stil

Blijkbaar toch te exotisch ofzo.
