Wildcat -- Go back to the AE Pistons (what the manual states), 24mm Ride Height F/R, Switch to JC Groovy / Double Dee (green) tires, take the C Hub off and go back to the A with 1 washer on a standard brace, take the weight out of the front triangles, add at least 1 washer under the front ball stud, rear lower shock inside position. I also only tried the losi springs on my B4 at hobbytown once and went back to the regular brown/green setup. Never liked how they felt, switched to Kyosho springs (pink F/white R) and they were better, now i run Avid (Red F/Yellow R).

Oh and dont come out of the corner hard onto the straight. you need to roll onto the throttle, especially at CV.
