I would order a set and try them out, i fought traction for 5 years with my truck. Put on double adjustabe drag shocks, tubbed the rearend for a big tire, swapped to a 29x15x15 tire on a 12" wheel and it would just blow them off even at low boost, first day with the brackets on and it planted the little 275/60r15 tires.
20" wheels arent gonna hook well either.
