Weight jack

Normally we leave our left rear weight jack at zero and adjust spindle shims for cross adjustment.Champ kart.
How many turns up or down can we safely move the weight jack to try quick cross swings without binding the rear axle? We usually see about 2 percent per round. We wanted to try quick 8 percent swings,about 4 turns from zero.Is that ok?? thanks
In other words.If the chassis is at 63 cross with the weight jack at zero.Can I take out 4 rounds on the weight jack to try 55 cross quick? We usually just move the weight jack about a turn or so off zero.thanks
