Building the ultimate track car

The ideea of this campaign is to raise money in order to complete my dream of transforming my mk6 GTI into a track rocket. I currently have the car modified at a certain level meaning modified suspension, basic engine mods, carbon fiber hood, battery relocated to the trunk, emptying the car of all the interior, big brakes and others. Seeing how the car handles with these mods it kinda pushed me to imagine something pretty crazy and also out of my financial possibility. We are talking about a 800 kg car using as much carbon fiber as possible and 800 HP from the 2.5l turbo engine from the rs3 and using the Quattro sistem from Audi. I know this project needs a lot of r&d but I think it is possible.
