3IS Inner Tire Wear
Where did you buy the parts and how much were they? I found it here for $67. Does this look about right?
Actually, the identical part (48076-24010) for Lexus is $67, for Toyota OEM it's $27. Can anyone tell me if this is the same part?

IMO the RCF LCA and rear camber arms are a must if you want tire life, I drive 20k+ miles a year and cant replace tires every 6 months.
I'm approaching 8k miles on this setup and everything looks perfect.

I did the RCF bushing and SPC rear camber arm, my camber was -1.8 and -2.1, the rear are now -.80 camber and toe is at .14. I did all of this at the same time because I only got 7k out of my OEM tires.

I wouldn't worry about it. Plenty of people install the Figs and RR Racing version that are significantly more rigid without issue. I had the Figs for quite sometime on my previous IS without issue. I am not sure why Lexus didn't just use the RCF bushing across the board anyway. You can barely tell a difference and if it eliminates the inner tire wear, it would be worth any slight trade off.

This is a very helpful thread. I bought a 2014 IS 250 and have noticed a vibration above 65-70 mph. It is almost always there but can vary in intensity; sometimes with the road surface. Is this higher speed vibration a common symptom from inner tire wear? I look forward to inspecting my wear pattern later tonight. Thanks again for all of the good info.
