1fast350

Hello everyone, I recently attempted to lower my new 2023 IS350 RWD with RSR downs. I have lowered many carts with similar suspensions but I am struggling with this one. I have the front finished, which I thought would be the hard part, turns out the rears I cannot get right. I followed a couple you tube videos but my rear lower control arm and front lower stabilizer have way too much tension regardless if I jack up the hub or not. I managed to get the spring in and managed to get the shop and end link back in place but the fromt stabilizer bar dont even come close to lining up, its off by at lease 1/2 inch, meaning the bar looks as if its a half inch short. I fought with the control arm bolt for 3 hours in order to get the bolt back in, way different from the videos. Any Idea what is going on here, I have the front stabilzer bar out for the moment so I can move the car but I have no clue what to do. any help would be much appreciated.
