I have a 2014 IS250 on coil-overs and my rear tire is now at -2.3. I blew out the inner edges of my tires so I need to adjust the rear camber. What do I need to buy? And also what is the factory recommended camber? I seem to can't find that anywhere. My front left tire is also -0.7 more then my front right. Is that normal?


I am looking at this, will this be all i need?

First, the link is for a 2IS part...I realize it says 2006-2014, but the 2014 IS Convertible is built on the 2IS platform. You want parts for a 2014 +, like these: https://www.summitracing.com/int/par...2450/overview/
Second, Camber difference side-to-side should be no more than 0.5 degrees, that is Toyota's recommended spec.
Third, 2014-2016 IS RWD have front and rear Toe adjustments only, 2014-2016 IS AWD have front Camber adjustment also...in addition to the front and rear Toe.
Last, as for the recommended specs, confirm if your IS is RWD or AWD, and what OEM wheel size it came with, and I can point you to the specs.
Just for reference, below is my 2014 IS250 F Sport AWD alignment specs after being lowered on RSR Downs:
The spec ranges are different than yours, so I'm guessing you have a RWD.

 

Thanks for taking the time to answer. So the link that I provided would not work on my 2014 3is RWD?

 

It wouldn't work on a 2014 3IS anything.
If you look at the pic of the two parts, the construction is completely different. Additionally the wrong part is $46 more

 

For alignment specs, see post #26 here: https://www.clublexus.com/forums/sus...bushing-2.html

this is what you need to get to correct your rear camber settings. i have a set on my 3IS and i have my rear camber set at -1.3 degrees




and for the front camber settings, that might mean that one side (looks like your driver side) is a little lower than the other side.
