Hi, I would reccomend the following arms for the rear

* Megan Racing Rear UPPER* Camber Arm
* Megan Racing Rear LOWER* Camber Arm
* Megan Racing Toe Arm <---- This will let you 0 out the Toe for minimal tire ware

I was struggling with the same questions....
Camber is not adjustable on the 2is chassis (only a little on the AWD chassis), however toe can be adjusted... depending on how far you lower.
Say YES to camber kits for front and rear, but don't go buying toe arms unless you actually need them.

Toe is adjustable on a stock suspension, camber is not.

^So with all of that said, you will want the "camber arms" - P/N : MRS-LX-0311.

There are two arms used to adjust camber in the 2IS Rear Suspension. This allows for full camber / wheel centering adjustability.

* Rear #1 - MRS-LX-0321
* Rear #2 - MRS-LX-0311

I recommend pairing the above parts with the rear toe arm

* Rear Toe Arm - MRS-LX-0371

Optional:
* Rear Lower Control Arm - MRS-LX-0322
* Front Camer Arm - MRS-LX-0313

^ Buying all of that and taking it to your average shop for an alignment is going to do nothing more than confuse them and make the bill go up. Unless you are trying to do something very specific with your alignment setup too much adjustability is more likely to hurt rather than help.

I have both upper arms, and toe arms on my car. In hindsight you really only need the camber arms quoted by Gville, and the toe arm is optional. Personally I am glad I have the toe arms (they make dialing the toe in much easier, and the easier you make it the more likely you are to get what you want from the alignment shop) but the 2nd upper arm was a waste of $$$$.

The second upper arm, is certainly not a waste of money, it actually helps readjust the position of the wheel. As you may know, depending on how low you go, and the amount of camber you run from the first arm, the wheel position will not be center. The second arm allows for more adjustability camber wise and allows you to center the wheel. This aids in eliminating rubbing and essentially let you dial in your wheel fitment perfect. ( I am running 4 different arms through trial and error)

At the end of the day its really what OP is after. If OP wants a slight drop and to correct or add a few degrees of camber, you can certainly get away with just a camber arm and toe arm.

If OP wants to go super low, and or with an air suspension, then I would highly suggest in investing on the second arm and dialing in everything perfectly.

i got the Figs Engineering Mega LCA's for my rear It is a bit pricey tho, but worth it from what I've heard.
Apparently its the "solve-all" to camber adjustment for any 2is rear.
Mike ("Figs") is a really great guy to talk to regarding all your alignment / suspension problems or questions!

So i already purchased Megan Rear upper camber arm MRS-LX-0311 and Megan Rear toe arms MRS-LX-0371 for my 2008 IS 250. Will these two be enough to adjust the camber to -1.0 and toe to 0. Looking to increase the life of my tires.
What would the Rear upper adj no.1 arm MRS-LX-0321 do? And besides adjust ability, do these arms add more stiffness to the ride and allow better handling?

^Yes; just visit your alignment shop of choice and tell them exactly the specs you want.

I'm finally gonna throw mine on. Been holding them for a few months now. Mike at Figs helped me out with a few other purchases. He definitely is helpful.
