Have you tried it without them? That type of bar is great for drag racing as the torque reaction "plants " the tires. In a cornering situation it puts the rear suspension in a bind. I will say that every driver seems to have their own idea of what is best for them. Some of the best handling early Mustangs were the 69-70 Trans Am Mustangs hand they used a heim jointed over ride traction bar similar to that of a '65 Shelby. The bar was ONLY used to combat wheel hop on heavy braking.
If you are fast the way you are , don't change. I'm just saying your bars were designed with straight line in mind , not cornering.
