Do I need toe arms?
 

I am currently looking to move to coilovers and lower my FRS. On my last FRS I went with B16's and the whiteline F&R camber kits. If I am going to go with LCAs on the rear this time instead of a camber kit, do I need adjustable toe arms as well? thanks

I have had no problems getting toe to zero (or a touch of toe-in) with rear camber between -2 and -2.7 degrees. Depending on your target camber, you could be fine.

Im looking to have 1.5 degrees in the rear so I may need toe arms

Unlikely, I've never come close to using the full adjustment on the factory toe arms, they've got plenty of adjustment range.

I think they're only necessary if you're chasing stance or if you want something easier to adjust.

You typically only run into issues with the stock toe arms if you're adding, or removing, a lot of camber. If the car is slammed and you want -1.5, you might need toe arms. If it's not dropped that much you're probably fine.

I can get -2 no problem. I tried to get -1.25 and there was not enough adjustment in stock toe. I was changing back and fourth for auto x and daily driving. I have since just settled on -2 and deal with tire wear.

I'm not looking to lower the car that much... I think I will see how the LCA install goes and get toe arms later if needed. There are a lot of mixed opinions when it comes to these squared set ups. I just don't want to get into the install and wish I had the parts, but also don't want to waste the money of it's not necessary.

How low is the car?

1 1/4" roughly, all around
