im about 195 with gear on and i had standard sno pro fox zeros in the rear with sno pro rear torsion springs on a standard 03 f7. i have fox floats in the front off an m series sled (1.25 in shorter center to center) and c and a pros for skis. this was a much better setup than the standard but still had some ski lift in the corners. after reading a wealth of stuff on setting these sleds up i went back to the standard torsions in the rear and had the rear shocks setup for my weight, revalved and a little quicker rebound. i dropped a little a pressure in the front. like 75 down to 55 pounds. sled feels much better now. almost no lift. pushes just a bit but i do have 187 studs and i need fresh carbide. i just run 10 in standard carbides on the c and a skis. i am going to drill a half inch up on the limiter and get just a little more pressure in the front. i think it will be perfect then. softer rear suspension with properly setup shocks is way nicer and better handling than stiff springs. just need the 05 seat and i will really like the sled.
