Hey Andrew
as Todd has already mentioned we are pretty lucky and dont have to worry about the power to weight restrictions just yet.
Obviously your not going to go and get a car that you couldn't/shouldn't drive to its potential in a day to day environment and always have complete control.
Sorta like when peeps get the bike licence, a 250 is just not good enough or powerfull enough for them as they are the next Valentino
So they get themselves a bigger bike and within a week they crash it, put themselves in debt cause its a right off and hurt themselves or others.
Drive your car and be safe as i dont want to go to anymore funerals this year or for the next few year
Cheers GMB
