I've just got myself a cheap RST and i want to turn it into a track car, the engine is standard bar a chip,-31,zorst,air filter and intercooler. the engine will have to stay like that as money is tight right now, i wasnt to improve performance of the car so i was thinking of putting it on a diet a major one! i've done all the normal things like taking the seats out bar drivers one carpets, door cards and so on but i want it to be lighter so is there any metal that i can cut away and the car to still be safe? i was thinking spare wheel well and drilling holes in the inside of the doors and removing the lecky windows and fitting plastic windows? any ideas would be great??
