New owner here...Just picked up a 07 IS250 and found this thread researching front tire wear. Mine are wore to the cords on the inside and the rest of the tire is like new. I ordered a set of Figs bushings and hope to get decent life out some new tires.I'll post up alignment specs and pics of the removal and replacement in a week or 2.

I'm getting ready to lower (Swift), LCA's ball joints (if Mike gets them back in stock soon...) SPC ball joints and new wheels.
I went through the toe issues with my IS300 and toe (front tire wear) was the culprit there as well.
I'm sub'd to this thread and will report back when all work is done and see how the alignment works out.

I really shredded my front tires from pretty normal driving. The insides are worn to the cords! On my second set of tires. 1st set were OEM Michelin PS2's. 2nd set were Hankook Ventus Evo K12's. I'm at 42k miles right now. Probably going to go with the Michelin PSS's, but dam I need to do something about fixing this crazy front inner wear issue. Any suggestions on alignment settings before I buy my 3rd set of tires? Attached are my alignment specs from over 2 years ago.

something to let you guys know that we will have adjustable inner bushing for the upper control arm. Should have 40 tomorrow or next week.

alignment spec
Are there any recent updates with tire wear on this alignment spec? I am looking to install new tires soon, my current status on my 2008 IS F is 30,000 miles on the OEM tires. They have not worn to the cord but it is evident that they have more wear on the inside of the tire. The car drives perfectly straight. Any advice would be appreciated.
So here's the spec sheet. It had 1/8" toe out from the factory, which is great for performance and terrible for tire wear. I had Jeff at Gran Turismo cut it back to 1/16" or from a little over 3mm to about 1.5mm. I'm going to see how this wears for street driving. Jeff also put some match marks on the toe links so I can toe it back out for track days.
FYI - one full turn equates to 3mm toe change on the side you adjust. I'll be resetting my toe to the factory spec on track days by lengthening the link 1/2 turn.
My cross camber is excellent, and with the car static, both sides read -1.0 degrees. I'd rather have -2.0, but at least they're the same. Rear cross camber isn't quite as good with -1.0 on one side and -0.7 on the other. Oddly enough, Jeff told me the right rear was actually toed out, so they corrected the rear toe, and reset the front toe to arrive at the numbers on the attached pdf.
I'm going to see how this wears, but I suspect it will be dramatically better. In theory, dynamic toe should be inward, so with a very slight outward toe, it might actually go to zero while cruising the freeway. In any case, I'll be monitoring it and reporting back what I find. I'm making an 1800 mile trip over the weekend, so I'll have some initial findings pretty quickly.

Yes, there is, but I haven't taken pictures yet. The last alignment worked.

Gran Turismo in Chamblee. Definitely the best place in ATL.
