^^I actually don't think that that's accurate. I think that the MCS is an exceptionally tough competitor, but they dominate the class because they are simply so prevalent. With the right setup, and the right driver, I think that an SVTF can be a serious national-level competitor. If nothing else, you could do just great Regionally and in Division.
Don't waste another minute waiting on parts, or anything else. Just get out there and start racing! You will suck at first, and you will be slower than many other cars, but the only thing you will regret is not starting earlier...
