Suspension Questions
 

As the title says i have a couple of question I cant find. I am inept when it comes to searching in forums.

I am upgrading my suspension slowly.

1. I am getting SPL RLCA can i run it without getting the SPL adjustable toe arms? Anyone have documentation of installing the SPL RLCA.

2. Currently, I have 1 coilover higher than the rest can this make the car shake over 65 mph ? ( will be fixing soon in like a day or two )

1. Yes, yes, https://www.splparts.com/content/SPL%20RLL%20FRS.pdf
2. If it's a only a little bit - no, if it's a ton maybe. More likely an unbalanced wheel or bad alignment.

Thanks for the reply. Yea im not sure. i got it professionally aligned and got paper work on how bad the previous alignment was and got the balanced check 3 times it was good. I did find that my rear is having a weird thing where the rear ride height changes on both sides ( 1 side is on the normal ride height and 1 side is higher and then it switches over sometimes ) im checking the whole rear tomorrow.
