NONE OF THIS DISCUSSION IS TO CORRECT A DRIFT PROBLEM. My car has never had a right or left pull. The purpose of this thread is to document wear patterns with different toe settings in hopes of finding a good street setting for maximum tire life. If the car pulls left or right, you have problems unrelated to toe.
Thanks again

The first photo is before the brackets were installed. The second is after installation. What do you guys think? Will these settings save my tires?
BTW, the car still drifts to the right, but not as much as before. If I hold the steering wheel straight, it will go straight. But, if I let go, it'll drift to the right.

Went in to the dealer because the car was drifting to the right. Well, here's my alignment printout. I asked for 1/16" front total toe-in and 1/8" rear total toe-in. I guess I got half of what I wanted. The printouts show "degrees," but i think it's in inches for the toe. I don't know why the tech didn't bother to match the camber. They did install the camber brackets for the front per the service bulletin.

Subframe needs adjustment because my cross-camber is too much or because of the included angle difference? Would adjusting the subframe lower the cross-camber?

Numbers look good. The proof is in the pudding - how is it wearing?
My inside edge wear seems to have slowed quite a bit since the last adjustment inward (closer to zero, might even be slight toe in.)
I still have a suspicion if we were to replace the rear LCA bushing with something harder, or even a spherical bearing, we'd see a lot less inside edge wear problems even running a little toe out as I would prefer. I think Lexus put a too soft fluid filled bushing in that spot that didn't get upgraded when they built the F. It should have been changed to provide better toe control.

Well I can tell you the cars pulling to the right because the camber is lower on that side. Camber really needs to be closer to even from side to side. I had this issue as well and didn't solve it until I got a front camber kit.

I find if your running a bit of toe in you will be slowing the inner wear on the IS. This was what I did for my IS250 just recently since I was running 0.00 toe I was wearing the insides out. So trying toe in should be alot better when it comes to even wear.
I would say something like 0.05 toe in the front and 0.00 toe in the rear. I ran 0.00 toe in the rear and only got a tiny bit of inner tire wear.

I have more of these coming. Just one in stock right now
http://shopfigs.com/v1/index.php?rou...&product_id=99
I also have an offset version.
I plan on testing the caster angle and tire wear with this over the next few months.
Lobux, replacing the rear LCA with the spherical makes the entire suspension much quicker to settle and locate with trapping ernergy in that bushing. I was not aware that any bushing was fluid filled. Do you know that for sure?

Everything else seems symmetrical except for the cross-camber. My .01 thrust angle shouldn't be a problem. I'm hoping that a subframe adjustment will do it...if the dealer is willing to do it...
