Home' Australian Automotive Aftermarket Magazine : Australian Auto Aftermarket e-Zine - April 14 Contents As a top level tuner, AFP knows what makes
Subarus tick – and what combination of
performance parts are required to put together
a fast, but importantly, reliable car. It didn’t
hold back with this one.
Other than decades of careful engine and
chassis tuning experience, the only secret
ingredient is a built up 3.6 -litre flat six
(commonly found in the Tribeca SUV),
combined with a state-of-the-art satellite
guided traction control. The result? A world
record for a street-legal WRX with a staggering
8.20 second quarter mile at 173mph.
“The car has been performing great, and the
clutch has been faultless,” AFP’s Andy Forrest
“The clutch is smooth enough that it allows
me to roll progressively up to the start beams
then deals easily with 1000-plus horsepower
dumped in at 6000rpm and then flat shifted
at 9000rpm. It’s an astounding result that’s
well worth a Youtube view.” You can search on
YouTube for all the action.
Xtreme’s flagship 230mm twin plate carbon
clutch handles the monstrous power and shock
loading with ease and has been
running in the car for an entire season
with plenty of life left to give, which is
not something that can be said of all
clutches Mr Forrest has used.
“My previous clutches have always
needed changing out two or three times
in a season, this one measured up like
it could run another season when
inspected recently,” he said.
It’s not just about standing starts
either. The AFP Subaru almost clean
swept the UK’s tuner shootout events last
season, winning Ten of the Best (a multi-skilled
event that includes elements of drag racing, top
speed, and time attack), Marham 30-130mph
race, MLR sprint championship (five rounds),
and another eight separate drag racing events.
In addition to setting the world record 8.20
quarter mile time, the car also set a new UK
record for 30-130mph (and astounding 4.01
seconds), and a new Impreza record for
standing kilometre speed (210mph).
“I'm happy to say the Xtreme Clutch is one
of the few 'fit and forget' items that I have fitted
to the car. (There’s) no need to warm it up
either unlike some other carbon clutches,” Mr
“I'm well impressed, and I don't say that
And there’s more to come from the car as
well – the AFP Subaru recently set a 178mph
quarter mile terminal speed on an un-prepped
runway showing there’s still plenty of
development potential in the car.

In Formula 1 during the 1980s, teams and
drivers shot out of the ground like mushrooms.
Vincenzo ‘Enzo’ Osella, a businessman from
Turin who set up his own business building and
racing sports cars after finding his feet with
sports car constructor Carlo Abarth in the
1970s, fulfilled his dream of competing in the
In the era of the so-called front apron car,
Bilstein played a decisive role in the most
successful years of the Italian racing team
Osella Squadra Corse. Perfectly matched to
Formula 1 conditions with non-adjustable,
monotube, gas pressure, high-performance
shock absorbers with an external diameter of
46 mm and M52 x 1.5 external thread, the
suspension specialist brought the turbo power
of the Alfa Romeo engine into perfect harmony
with the car’s ground effect.
Italian driver Piercarlo Ghinzani and
Austrian Jo Gartner collected a total of five
world championship points in 1984 with their
vehicle, which was too heavy in comparison
with its rivals and as a result, inferior. The
shock absorbers for the cars of the former
Formula 1 era remain in demand to this day.
Once the archive in Ennepetal had sent the
corresponding construction drawings to
Australia, as requested, Bilstein technicians
from Sydney Shock in Sydenham (NSW)
restored the shocks for the Osella Formula 1
racer on-the-spot and used modern racing
accessories for historical vehicles from the top
class of motorsport to bring them up to state-
of-the-art of suspension technology.
Just how well these shock absorbers
functioned at the time is amply proven by the
successes of the McLaren team. Between
1984 and 1986, Austrian driver Niki Lauda
and Frenchman Alain Prost took the World
Championship title three times in a row with
the support of Bilstein.
“Our trained staff will rebuild and refurbish
any Bilstein to their original specifications,”
says Bilstein R&D specialists and Aussie
suspension experts Paul Joyner and Jonathan
Where necessary, a comprehensive archive
can provide all of the construction
documentation required for this purpose. This
applies not only to shocks which Bilstein used
to have in its past production programme in
but also to the reconditioning and
remanufacture of other makes. With the help
of the original shock absorber, the Bilstein
technicians then produce precisely fitting
shock absorbers in ultra-small series of
between two and 100 units.
