Back end feels weird..

[xavier240]

hello zilvia. i recently bought wheels 18x10.5 +7 and installed batlle version rucas. back end was all over the place, went and got alignment right after. i asked if toe would be in spec since i didnt have toe rods on and he said it wouldnt be a problem. well its all under the table so i didnt get a sheet or anything but the back end is still kind of squirrely.... and it rained today so it was a death trap drove real slow home from work. rucas are maxed out btw. im just wondering if anyone else had the same problem but i kinda feel like once i get these toe rods on with the alignment i should be good right???? guess i need some reassureance. btw its my first time running stretched tires and big wheels. i just dont feel like it should be squirrely in the rear... especially since i didnt have any problems before hand. i pic so yall can see. any info would be greatly appreciated.
