3. NEW CAR SHAKEDOWN
At Radical, we pride ourselves on our quality control and rigorous testing procedures that we have in place
for every new car. All new cars are subject to a 100 point post production inspection and track simulation on
our rolling road dynamometer prior to delivery. However, it is not possible to replicate the forces exerted
driving around a race track. The first time you drive your new SR3 around a track is the first time the car has
experienced the G-
procedure is followed for all new cars.
3.1 SHAKEDOWN GUIDE
Warm the car up and complete the pre-session checks. The first track session for a new car is also the first
time the brakes have been used under load. All cast iron brake discs for competition use need to be bedded-
in to ensure heat stabilisation and improve resistance to cracking. Cracks or warping can occur during the
first few heavy stops if careful bedding is not carried out.
Your car comes fitted with carbon metallic brake pads. To bed in the brakes and achieve maximum stopping
power, a film of carbon must be transferred to the discs. Additional notes on brake bedding can be found in
the following section.
To help with brake bedding, initially blank the brake cooling ducts off ¾ to increase temperature build up.
RUN 1 (OUT & IN)

mindful that the brakes and tyres are still new and
Start to build up brake pressure, and roll some more speed in to the corners. Bring the RPM up to
8,000 before shifting up through the gears.
Technician:
o Check the tyre pressures
o Check the running temperatures of the oil and water and adjust any blankings in order to ensure the
car runs at target temperatures
o Again, remove the engine cover and inspect the engine bay for leaks
o Re-check the wheel nut torque
o Allow the brakes to cool for a few minutes before heading back out on track.
