the metal ring doesnt have to go to that side. i just threw it on for the pic. it was a perfect fit for me. i have pictures of a few steps i took while putting it on my car i can send anyone who is interested to see the TIH on the car
i actually never installed them. i bought them from someone on this forum about 4 months ago. i dont have a part number but the drop rate is 1.3 inches in the front and 1.2 inches for the rear
