It would be nice if Cat offered a race edition F5 and F7. To include sno pro cross link shocks, clear gas tank. Stiffer springs. Basically a sno pro chassis. Most racers add these things on anyway at a pretty steep price so the increase in the price of the sled wouldn't matter because they spend that extra money anyway. I bought an F5 standard to race, then got the real sno pro shocks, clear tank, stiffer springs. That's alot of money.
