I am not sure how that would equate to raising the rear only 1.25 inches. It looks like it would raise the rear a lot more as that mounting location appears to be at least 3 to 4 inches lower than the factory mounting point.
What is the pinion angle when all is said and done?
Please do not misunderstand my questions, I think it is a great concept. I just wonder about pinion angle and ride height. Do you have any pictures of this on a car?
