Bought a 2010 IS350 last week, traded in my 08 IS250.. (don't know how I ever drove one now that I have the 350) Very happy with the upgrade to say the least!! I noticed the car had alignment issues due to f sport springs that were installed on the car. I had Lexus do an alignment on it today and my camber is -1.5 on both front wheels. Which as everyone knows Lexus didn't make it adjustable. So I'm looking for some help/ info regarding which route to go with how to get that camber back to spec. I just have stock 18's on the car (225/40/18 fronts) and as mentioned it is sitting on f-sport springs. I've read into the SPC ball joint kits and they seem to have decent reviews. They handle anything up to 1.5 +/- which would solve my issue. The Megan UCA says its for more negative camber for people that really want to drive aggressively. It is also more expensive. Being that I'm just running stock wheels lowered on f-sport springs.. Would the SPC kit be suitable? Thanks in advance for any help.

Like in my PM to you, I'd recommend just leaving it be and spend the money on FIGs LCA bushings instead.

What was the toe spec they set the fronts to?

Get figs bushings, I am going to be more setup like you with my isf. I have a set of new Megan arms that I was going to modify so I can have positive camber when lowered but it isn't realistic price wise when figs bushings will get me where I want with oem or better reliability.

The thing that kills your tires is your toe and not so much your camber. I believe lexus bushings aren't as "stiff" as the figs bushings which is why everyone is telling you to get the bushings.
With the figs bushings, your toe doesn't change as much, saving your tires in the long run.

If i remember corectly they were able to pretty much zero out the toe specs.. I think they were like .03 maybe? The thing that gets me is that the report tells me I have negative camber meaning that the tops of my wheels are tiled inward toward the engine.. however the tires that are on the front are worn on the outer edge.. I'm wondering if the tires were swapped at one point.. doesnt make any sense to me..

Outer edge wear eh? Yeah, if you're not the original owner of the car, they could have dismounted the tires and swap them around on the wheels...I do this actually. OR, you might have under-inflated the tires OR caster issues.

But to start, I'd get those FIGs LCA bushings.

I have the same problem. New tires are getting worn on the outer edge.

edit: searched and found my answer.
