I have been using the search function and doing a lot of reading about adjusting the height sensors. The rear of my car always looks a bit low in comparison to the front. I’d like to level the car up by raising the rear suspension slightly, likely about an inch or slightly less. I know the sensors can be moved to achieve this but I’ve read some conflicting information about how all 4 sensors work together around the car. If I just move the 2 rear sensors the same amount to raise the car (I’m assuming I’d move both rear sensors downwards to raise the car up) is that going to give me the rear raise I’m looking for or will it affect the front ride height as well?

I appreciate any experience or advice anyone can give me and please do chime in if you’ve done a similar process on your air suspension.

Here is a picture for reference. My driveway has divots sunken in so the picture makes it look more level than it normally would. When the weather is better outside I can provide a picture on level flat ground.

Realize that the fender arches are higher in the front than in the rear so you can't judge by wheel gap. Changing ride height will alter your alignment to some degree, if you do manage to get it lifted in the rear have your alignment checked afterwards.

That looks normal. Raising the height may make the ride a little stiffer, at least in the rear.

It seems strange to me that Toyota spent so
much time and money to engineer this car to near perfection but they didn’t look at something so simple as matching the wheel gap between the front and rear wheel arches and even placing the rear wheels in the centre of the arch....

I will get the car on level ground tomorrow and take a few pictures. I don’t want to make adjustments if it’s going to affect the ride but it just doesn’t look right to me.

Here is a picture of the car on level ground after a quick wash.

That looks as it should. If it rides good, dont start messing with it. I've been thru this and it caused a year of headache. Just leave it be. I have coil spring suspension and ended up replacing rear springs with 01-03 springs and got a better ride and level stance. I agree with the bad design on not centering the wheel.

With coil springs as you’ve described does yours sit the same as mine in the photo?

My 04 UL looks the same as yours. I also wish the wheel gaps had a more even look. I have chose to leave mine alone and live with it. I don't want to go down some rabbit hole of suspension and alignment issues.

My 02 UL on air looks like that too. The front wheel gap is always slightly more than the rear on level ground. Mine was calibrated to factory specifications by a local Lexus dealership after a rear-end collision damaged the rear sensors, and they only got the calibration correct on their 3rd attempt.

At the supposedly correct calibration (the most recent of the 3 they presented to me), they said they got it right this time and measured everything to the factory specs I sent them, and it looks pretty much exactly like your picture above.

Thank you for the comments. I guess I will just leave well enough alone. It’s just a little maddening that with the enormous time and meticulous attention to detail they didn’t pick up on these simple aesthetic deficiencies.

When vehicle speed reaches 100km/h or above, the front air suspension lowers itself to achieve the 0.25Cd drag coefficient (improvement over default 0.26Cd) and enhanced high-speed stability. I suspect the front wheel arch gaps would look pretty even with the rears if you take a picture while rolling faster than 100km/h.

Front wheels must turn and with the LS 430 they turn a lot. Rear wheels do not turn thus the front needs larger wheel openings.

Stance looks right, don't change anything. If you do change stuff see if you can change over to the Sport Suspension springs, bushings and shocks. They DO change the ride and that way you can get rid of the Air Ride suspension that will eventually become an issue.

Very close, the front on mine is a little bit lower. I used to have those wheels also.
