Excessive Tire Wear
Looking for some suggestions as to the cause of the excessive inner tire wear I am seeing on my last 2 sets of tires. First set lasted 4K miles, second set lasted maybe 8k miles at the most.
I have a 2014 GS350 AWD lowered with the J5 coilovers and the figs rear camber arm. Alignment was checked and adjusted to factory specs before the latest set of Michelin super sports went on. The shop mentioned the toe was way off causing the first set to wear prematurely. Now I'm starting to wonder if there's something not tightened down that is allowing the alignment to change over time?
Thanks for your help!

You need the RR Racing USRS.
It prevents A LOT of the inner camber wear. Theres huge threads on them on the ISF section.
Contact us for pricing and we can get it shipped to Canada ASAP.

I work at a dealership so i put my car on the lift the other day to do some fluid changes and was inspecting the suspension and noticed torn bushings in the rear on the control arms, cant remember which one it was but im guessing it is one of the culprits of this issue. Im sure its causing some sloppyness, ill take another look and take pictures and post them here. Im planning on replacing them in the spring before i put the 20's back on and see if it will wear out my new tires.

remember lowering a car changes a lot of the geometry and the biggest thing people forget to do is to change the preload on ALL the bushings that were affected.
the preload is set to factory height then when lowered this position changes, twisting the bushings at rest.
if kept like so for too long it will cause premature bushing wear.
factory bushing are soft for that nice lexus ride, and they do wear over time. they just wear faster on lowered cars that fail to properly preload them.
what I ususally do is I take it to another shop for an alignment.
not all alignment shops are created equal. there are so many variables that equate to poor alignment.
tire pressure, alignment rack calibration, weight on the car loaded/unloaded, etc...
also when new wheels/tires comes into play, a new alignment should be done.
I know this is not cost effective but the wheels/tires are now slightly taller or shorter causing once again for the geometry to change.

I'm having the SPC arms installed today. To me, -2° camber is too much for rear wheels especially when it causes this kind of wear pattern that most people wouldn't see until the tire fails or is near failure.
