Finally got a chance to get another alignment for uneven inner tire wear. Could someone help me interpret these results?

I am lowered to about 0 finger gaps all around.

 

Looks like you're -2 degrees I front on both sides with -1.4 being the max normal and -2 degrees camber in the rear which is on the higher end of within range for the rear. Toe is set within specs. Guess you're about as good as you're gonna be without camber parts.

 

Looks like the red items are just outside of the normal range and that would be expected when your lowered.

Just had mine done I am on F-Sport Springs/Shocks (I assume you are lower) and I came in at : -1.4 Left-F / -1.3 Right-F / -1.6 Left-R / -1.8 Right-R (camber).

The front TOE looks about the same as mine although your rear toe is higher - mine is .05 yours being .16 although still within spec. If it is within spec I don't see any need to be concerned.

 

What are you lowered on? I am lowered to about 0 finger gap all around. And the best they were able to adjust my toe was to about .1 range on the rear.

My rear doesn't wear out as fast as my fronts though. I can easily get 30k on rear but fronts I can only get about 20k.

 

I am on F-Sport Springs and Shocks - probably an inch higher than you.

 

I'm lower than you Victor, my rear is both at 0.04 and both fronts are at 0.03.

 

Are you serious?! How the heck.... Do you have camber kit?

 

No I don't, no camber kits. I'll txt you a pic of my alignment sheet later.

 

This is your Toe measurement not your camber correct?

 

Toe, correct. I don't have much camber either.

 

The insides of your front tires are wearing faster than the rest of the tread, am I right? I think many of us (especially with lowered rides) have a similar problem. So far I've been mitigating the problem by having the tires unmounted and remounted left-to-right every few thousand miles, but I'm planning on getting an alignment done by a performance tuning shop who knows what they're doing rather than a monkey shop that just follows the specs that they read out of their book.

I've read that all we really need is a bit more toe in on the front wheels. On RWD cars, you need a bit more toe in than on FWD cars. Since the front wheels are being pushed by the rear wheels, they have a tendency to rotate around the kingpins towards the back of the car, causing some excessive toe out at speed, which then causes feathering and extra wear on the inside of the tire. Apparently this car does not have enough toe in from the factory, and the problem is exacerbated by lowering the car. Unlike what many people tell you, it is NOT a camber issue.

That's my understanding, at least. And I intend to find out soon enough if that's true.

 

I will be interested as to what you find out. I too have been getting the alignments at my local Lexus dealership and I can assure you they know very little about what to do with a car once it has been modified. Even if it's F-Sport.

 

Looks like you need to bring your vehicle to alignment shop with the proper expertise to see if they can adjust it properly. The geometry of the vehicle may need to be adjusted as well.
