Hey all,

As I've owned my 2007 IS350 for the past 2 months I began to notice that the car pulls slightly to the right when the steering wheel is level, so to go straight the steering wheel has to be *slightly* to the left. At first I thought this was a simple alignment issue and shrugged it off as an easy fix.

Well I was putting some air in my tires today when I noticed that the front left side of my car appears to sit lower than the right side, even on a flat surface. So to confirm this I went to see how many fingers that I could fit between the top of the tire and the fender on each side. The left side I could fit 3 fingers in and it was very snug, while on the right I could fit 4 fingers in with a good bit of room to spare.

Would anybody have an idea of what could be going on here and if it may be related to the aforementioned alignment issue? My car is sitting on a stock suspension setup.

I could be way off here but this occurs since the driver seat is on the left hand side & because we don't have an LSD thus the back right tire sees most of the force from the engine since typically there is less traction on the right side of our cars, this the chassis flex, over time, makes the springs wear out due to the two culprits I mentioned above.
Cliff notes it's normal. However u have a substantial amount of height difference. So unless you are a really really big guy you may be hitting more pot holes on your left tires then on your right not to mention most united states roads are slightly lower on the right side. This is done for water run off & in case u fall asleep behind the wheel the road, theoretically, will push u off away from on coming traffic

My experience in this topic comes from Jeep Wranglers. This was always the case with Jeep Wranglers.
A little tidbit, rev your car hard while in park or neutral & have someone watch the trunk while standing in the middle/behind the trunk from a couple feet away from the trunk... Ask them which side of the car dipped down towards the ground first?

It's the "Lexus Lean". Mine was like that too when I was on stock and fsport springs.

Sweet. As long as it's normal it is just one less thing to worry about. Thanks guys.

It's odd to me that you have so much spare room on the right side though. I flip my springs on every car at the 60k miles point... Wonder if that would assist u?...

I was already planning on buying F-Sport springs soon. Since the car is so new (to me) I'm not sure what the previous owner did to it. I'm at 53k miles right now. I know that some work was done to the front left fender area around the wheel in 2009 just before the car hit 30k. Perhaps that had something to do with it. Here is what the Vehicle Service History from Lexus said about it.:

Thank god I have coilover.. I hate spring because there is no way to adjust even height...

the accident is definitely a big part to blame.

But if you search for the "lexus lean" you'll notice that our cars come with a slight lean to one side. No one has figured out why lexus does this to all of their cars (correct me if im wrong on this). Installing f-sport springs won't change it either. The only way to fix it is to get coilovers.

imo most of the components of the car are located on the left side including steering assembly plus the fact that most of the time we drive alone so there's no counter weight on the other side that make it balance that in the long run it will tend to lean on left side of the car, again imo.

Yea that's too much (if in fact u r on level ground)
That has to be because it was in a previous accident.
