Compared to the factory ZL1 bar, the first position is the same as stock, position 2 is 10% stiffer, and position 3 is 26% stiffer.
If you are upgrading to this bar on an SS model, the first position is 76% stiffer than stock, position 2 is 100% stiffer, and position 3 will be 130% stiffer.
Same as stock i the front is great with a big fat rear
