We are now in the process of building our mk7 GTi into a Production GTi championship spec race car. We thought it would be a good idea to build this small portfolio in order for enthusiasts to follow along the build process. We take no short cuts with our builds and always go the extra mile for every bit of performance possible.
Our race technician Luke who is responsible for the majority of the builds is a race driver himself and knows everything there is to know about these German pieces of engineering. His attention to detail and his knowledge on car set up never fails to amaze.
Onto the build
Now... Because the car has already been used by us for track days and blasting the back roads, we have already installed some performance enhancing parts with future racing in mind.
The car is already fitted with a full Milltek sports exhaust with a race cat, gripper front differential, custom Jabba remap, racingline oil catch tank and team dynamics pro alloy wheels. All of this, we will be keeping on the car other than maybe adjusting the map to suit the PGTi regulations.
Weight loss time!
As with most race cars, the first step of the build is to strip out all of the unneeded luxuries in order to shed as much weight as possible.
This begins with stripping all the interior such as: seats, plastic trim, carpet, sound deadening, airbags, etc. All
All parts were then put up for sale to generate money for the build!
As we are building this car to compete at the top of the grid, the weight shedding does not stop there.
-The car is first wrapped in a protection film as its now time for the dirty work!
-The Air conditioning fan unit is then taken out with the dash bar and all the other grubbing's under the dash.
-All the tougher rubber sound deadening on the floor and roof is heated and scraped off.
-Luke will then go on to drill/cut/grind out all of the unneeded brackets, fixings or structural supports (roll cage will fill in this job) that are no longer needed.
-The wiring loom is then also stripped of any unnecessary wiring then re wrapped.
You'd be surprised how much can come out!
Now that we’ve finished stripping all that weight out, its now time to add some back in with our roll cage! We’ve chosen to install a full FIA spec cage made out of a high tensile, lightweight alloy called T45. Luke is also fully qualified to install cages to the FIA standards and specifications.
Before beginning the cage installation, the fuel tank is removed as a safety precaution. Then the windows and doors, to help with access and to prevent damaging anything.
The next step is to begin installing the cage with tack welds to ensure that Luke is happy with the fitment. Any adjustments are also made at this time. Watching Luke work his way through each portion of this process makes you realise how much skill and experience is involved in installing a cage properly. A lot of it is done by eye and trial and error but he also uses a laser level at times when its needed. The metal is cleaned and prepared for paint before its installed to make things easier along the line.
