Ahh,I see your confusion (That sounded wrong. lol). Anyway, I've based the rules on the original "Touge Showdown". You see, in the original show, they based it on driving feel. Why? Bacause they are judging street cars. For them (and I myself), think that a street car should be a fun car to drive.
Now, onto my Hachi-Roku. I think that, for me, it's a very fun car to drive. So that's why I chose it.
Before the battle, I will be testing your tunes. (Remember to send them to me via Private Message.) I will pick the car that is most fun, for a street car.
Okay, so in the battle, it will be a battle of street cars. This time, it depends on who's car is quicker. So, to summarize it, the car must be fast, and fun! But mostly fun. lol
There are no PP limits, because there is already a HP limit, and Engine size limit. It's on the 1st page BTW. So, yeah, that's it I suppose. lol
Don't hesitate to raise your concerns. Every question so far has led me to improving this thread.
