i have the QA1 kit on my car, put it all on in my friends garage (no lift). only "modification" that i remember doing was on the back bolt for the control arms I had to notch it enough to slide all the way in. id take a piture to show your what i mean but the car sits to low....also Id bet youd get better customer service with MM, UPR didnt send the torrington bearings for my coilover kit and basically told me tough poop...the ride isnt too bad (coilovers in front & SVE springs in the rear, stock struts & shocks, stock tie rods and c/c plates) but as soon as i hit a bad road it gets pretty rough...the k-member is awesome tho, all the clearance in the world, if i ever needed to change my starter all i had to do is take off my right front tire, that easy...ive got the rest of my suspension parts (kyb agx struts/shocks, competition engineering bumpsteer kit, prothane offest rack bushings, and MM C/C plates so im sure afer its all installed itll be like a dream
