Hey,
the engine is stock :/ only with a few changes like oil cooler, exhaust and so on. but more tuning coming soon...
the race weight of our car is 1470Kg and we are racing against cars like: clio rs cup, porsche cup, porsche 996 GT3, SEAT Leon Cup, Opel Astra OPC.
yes the tyres are very skinny: 18inch/240 but now we changed the tyre size to 270
