I have a few suggestions for you.
#1 If you use a gyro, you will need a super fast gyro and steering servo (GY611 is best) or you will get steering wag at high speed (ask me how I know)!
#2 Two wheel drive is VERY difficult for a top speed car because of traction issues. I run 4wd with a 1515 and I get tire smoke at 50% throttle (3800 watt power system). It accellerates 0 to 80 in 2 seconds. I have tried 2wd and could not get it to hook no matter what I did. It was like driving on ice.
#3 A 1515 is good for a maximum of 4000 watts before the efficiency goes in the toilet. However, it is very difficult to harness more than about 3000 watts anyway.
#4 Light weight is almost a moot point when you need to add alot of battery power (and weight) to it anyway. I mean, do not make it heavy if you do not have to. But, puting time and money into the best drive system and lipos you can get is far better for a top speed car.
Please forgive my negativity. I do not mean to rag on your car. The design looks very good indeed. However, I have gone round and round with these very issues with ALOT of money wasted and I would hate to see you go through the same thing.
It is a beautiful design and I wish you well with it. But, I have seen this time and time again and have been down this road myself.
