I would guess the majority of the guys who own these cars do not leave them stock. So it comes down to want and cash. If you have enough of both you'll be the fastest, for a short time, untill someone out does you. I have not lost a race yet in my car. I am sure it is going to happen eventually and I am prepared not to give a crap. The guy who beats me will simply have more want. Sure I could dump another 10K into my car but I do want to jeopardize the love I have for driving it right now. And all you guys in the 05's should think long and hard about reliability and driveability when you go to forced induction just to win a couple of races. The only thing you need to answer is whether or not YOU enjoy your car. There is no justification for my car needed. My life is more than my car and I do not need to beat a punk in a 7 year old rattle trap to feel self worth. Although I have little doubt I would win that race.....so what.
