The Ginetta G55 GT4
Homologated for the international stage, the Ginetta G55 GT4 is eligible for competition within the Michelin Ginetta
GT4 SuperCup, British GT4 and a variety of UK and European endurance and sprint racing series.
Introduced in 2011 to replace the ground-breaking Ginetta G50, the Ginetta G55 GT4 produces 355bhp from a 3.7
litre V6 engine. The driver cycles through the gears with a six speed sequential gearbox with pneumatic paddle shift
system.
As Ginetta’s most popular export car, the G55 GT4 car is racing on circuits around the globe and in varying
temperatures and terrain. With that in mind, recent modifications have been made with hot climate competition in
mind, increasing reliability and resale value.
The Ginetta GT4 car is a multiple class winner in the Dubai 24 Hour Endurance race, proving its might as one of the
front-running endurance racing cars on the market today, whist benefitting from being one of the most cost-
effective.

Recommended Tools and Equipment
The Ginetta G55 GT4 is designed to be straightforward to work on. This section is designed to highlight the various
instruments you may need when working on certain areas of the car.
Wheels and Tyres
For a race weekend it is ideal to have 4 ½ sets of wheels, as detailed
below:
Two sets of wets - one to use and a full spare set.
One set of slicks - mounted for testing, plus one front and
one rear spare.
One set of slicks - mounted for racing. Using the spare front
and rear rims from testing to have race spares on.
In total this amounts to nine front 9” wheels and nine rear 10”
wheels. Keep in mind the tyres are directional and have different rim
widths for the front and rear.
The barcode on each tyre shown in figure 1.1 is used to identify your tyre nomination at a race weekend. This allows
the event scrutineers to keep track of how many tyres you have used throughout both the race meeting and the
championship year.
Charged Gas Bottle
The car is raised and lowered using pneumatic air jacks. The
compressed air used to actuate the jacks is stored in a steel cylinder
gas bottle.
The gas bottle can be connected on the right hand side of the car,
shown in figure 1.2.
The gas bottles can be supplied by CES Europe Ltd.
(www.ceseuropeltd.co.uk / 01295 279558)
Air Lance With Correct Hose
Each car comes with an air lance, used to connect the gas bottle to
the car, as shown in Figure 1.3.

Figure 1.4
Figure 1.5
Air Jack / Gas Bottle Regulator
Once the gas bottle has been connected to the car via the air lance, you are ready to raise the G55 off the ground.
In order to fully extend the air jacks, the regulator needs to be set to 34 bar of pressure, as indicated by the red
arrow in figure 1.4.
It is very important that you DO NOT exceed 40 bar of pressure as
this can cause damage to the air jack system.
The fittings and regulator can be supplied by CES Europe Ltd.
(www.ceseuropeltd.co.uk / 01295 279558).
ECU Download Lead
In order to download data from the car, you will need a download lead.
For cars with an M150 ECU, an Ethernet cable is supplied with the car along with the Motec software required to
download data directly to your laptop.
For cars with the M800 ECU, a UTC download lead is needed. This can be purchased directly from Ginetta.
(www.ginetta.com / 0113 385 4164).
Dump Churn
The standard Ginetta G55 comes with a dry brake filler only.
Therefore, a dump churn is an essential piece of equipment which
will be used for quick and easy refuelling of the car.
