one word...Nitto.
The stealth bomber will look like a standard car, sound like a standard car but go like a supercar. Its the only way to do them these days with all the negative views towards the modified car scene. Under the bonnet the car will appear to be totally standard but will be nudging 400KW. The brakes and suspension will be big dollar top shelf stuff though and may give the game away. Croydon Racing will be in charge of the tuning and set-up.
I can do a head identical to the one on my racecar as a 20K long engine package if you like.
