Tex is correct. Depends on how far you are willing to go. Narrowed plus foward a arms? Shaws? JJ&A? Where do you race, are you going to need those 4 snows or are you going to need paddles? Wheelie bar? Spindles mount tires? I think you can only go so far with a stock bike than they become a pain in the ass. The time and money spent on a strictly only dragger will be better spent on a rigid chassis. I've learned that from experience.
