Here's the situation, i was running a set of 19x8.5 wheels with 225/35 tires all around and my handling was awesome! I bought a set of 19x8.5 front and 19x10 rear wheels using the old 225/35 tire for the front and a new 235/35 rear. I also bought the spc lower control arms. Installing the LCA's I noticed the more I go camber out the more toe in was getting, I didn't have time to install the toe bushings so I reinstalled the stock arms. When installing the stock LCA's I tightened the bolts before lowering the car to the ground. Ever since this day my car doesn't drive right. It feels very loose in the rear end like it wants to slip out. What I've done since this is remove the 10" wheels and went with 8.5 front and 9.5 rear still using the old 225/35 tires and the new 235/35 rear. I had the car aligned and after explaining what I did to the shop they told me the correct way to install the arms. They loosened up the bolts to let the car settle ( which it did by about a half an inch) then tightened them. The car felt better but not like it used to before all this. I decided to completely uninstall the arms and reinstall them like I was originally supposed to. The car still drove somewhat better but not perfect. I then brought my tire pressure to 35 from 40 which also helped the stability. After all this the car is drivable but still doesn't feel as good as it used to. My next thought is the inner LCA bushings are bad and need to be replaced, so I am waiting on my whiteline ones to come in. I'm asking for any suggestions as to what would fix this issue, after I install the bushings and get another alignment if that doesn't fix this I don't know what else to do. I would very much like my car to drive like it did before. Please advise
Btw I'm lowered on Megan ez street coilovers, all the way down.
