What are some must haves for a street racing car?
Ok I will try to give a somewhat real reply……
You mentioned cornering and acceleration on a 10k budget. You also mentioned racing so I will assume you are in competition with another car/driver and/or time clock.
In short…… You can't be competitive in both cornering and acceleration for that budget when your foundation is a Dart.
You will get beat by every Evo, STI, Turbo Civic……. The list goes on.
I suggest you pick one or the other. Hard acceleration with modest cornering or Hard cornering with modest acceleration.
