Default F & R RCA's Installed, Now I Have Issues (pics)

Ok guys, so i figured that after installed both front and rear RCA's not only would it fix my camber issue but the car would ride better but wow it's horrible. While I'm driving I swear I feel like I'm going to lose control of the car. The only way to describe the feeling is hydroplaning, it's very difficult to keep the car straight and if I attempt a lane change or even touch the steering wheel a little bit the car starts swirving. Right after the RCA I got an alignment and the only issues that I noticed were the front camber, which is at -3.5 L and -3.1 R, and the rear Toe which is at -1.13 L and -0.77 R for a total of -1.90. Now I know I'm now going to need to buy toe adjustment for the rear but what's up with the camber up front? I installed the RCA's to improve camber but it actually got worse? How can I solve this issue guys because I'm seriously scared to drive the car right now lol ...

Here's some pics to help out:

Brand new Bridgestone Potenza RE050A Pole Position tires for the rear





And what my old rears looked like

All GS are created differently so therefore some requires adjustable toe arms and some dont from my experience. You can order the Megan IS-300 Toe arms or Pm FIGZ cause he just fabricated some. As for your front camber, it seems to me you dialed -3.50 & 3.05 and ended up being worst.. im just guessing your alignment guy went ahead and adjust it going the oposite way or it might just be maxxed out after settling.

you're rear camber looks fine almost close to spec... the reason why your chewing youre tire is because your toe..

mind if i ask what setting did u put your rear rca to..? left center right?? exact RCA or SAGE? or even your ride height at each fender to the floor. doesnt look like your slammed at all, kinda wierd with the front specs

another suggestion u can do is go with the front SPC adjustable upper control arms and just sell the front RCA.. i have front rca sitting at -2.5 front and slammed on 19s too but thats just mine. im gonna get SPC UCA soon and keep my rca on cause i want the longer shock travel..

The rears are Exact RCA's but I'm honestly not sure which setting they are set at since I didn't install it myself but I'm going to check because I'm taking the car back today for them to try and correct the issue. So the front UCA should help with camber more than the RCA's?

And the coils are nowhere near maxed out, it looks as if they've still got plenty of room to drop ...

Did you raise your coilovers up to compensate for the 1 inch drop?

TruPlaya get the adj. rear toes from FIGZ. It's just a few bucks more, would highly recommend those before megans.

Well I'm trying to find someone local selling them right now because I just can't drive this car like this right now, not to mention the fact that it will tear my tires up which are brand new, I will be contacting FIGZ though if I can't find these local ... Now another question, if I can't find these and have to wait for shipping, what is the best fix right now to eliminate the steering issues I'm having, because just now on the way to the shop getting on the on-ramp to the highway the vsc was going crazy and I was only at 35 mph !!

Ok so one really important question, are you guys sure the IS300 rear toe adjustable control arms will fit my 01 GS430? I just called Megan and they seemed really uncomfortable about the idea ...

And also, which vendor sells the spc uca's I tried searching but could not find them?
