Sorry for the noob question. But I'm trying to get my rear of the car to sit flush. I have KW V3s I'm noticing the remaining threads on the coilovers vary. Like the passenger rear has 7 threads from being maxed and the driverside rear has like 14 threads remaining from being maxed. It doesn't appear to be bound. Is this normal due to maybe the gas tank weighs more on the driverside? Just trying to understand if this is normal. Thanks

Additional information:
2009 Lexus IS-F stock wheels 30 psi all around. Only other suspension part is the Sikky rear sway bar with the adjustable endlinks that is set to zero load.

 

While I don't have an IS-F, I too have struggled with getting fender height even all around. Once thing I found is that if you force one wheel to try to be even, you throw off the corner weight of the car and you'll have tires leaving the ground on various uneven surfaces like angling into your driveway, etc. I intend to try the advice I am about to give you, but haven't yet so take it with a grain of salt. It is my understanding that you need to adjust corner weight to compensate for different weights. If you add more preload to the spring on a particular corner, it will raise the fender height on that side. This will then result is even distribution. The thing you have to be careful of is if your corner weight is off already, as you try to adjust height, you'll make things worse. Think of it as a chair with one leg too short and how it teeters on the opposite diagonal legs between the short leg and its opposite. I'm still experimenting with this myself over in the 2IS suspension forum. I don't think this is quite as straight forward as some make it seem.

 

Makes sense to a extent. So maybe change the damping

 

Corner balancing and ride height adjustment is not an easy process and takes much adjusting and readjusting. Take the car to a shop that sets up race cars to have it done right. Best if they have you sit in the car through the process or place weight in the drivers seat to simulate the weight for best balance/accuracy.

 

I think the common price for a local race shop alignment and corner balance is around $300 here in CO

 

What does this mean? Are you looking for visual performance?

 

I'm looking to buy an 11' IS-F Tomorrow, and it has KW V3's on them as well. The car is sold by a Lexus Dealership, and all the work has been done at the dealership, the previous owner had a good relationship with the dealer.

When I went to go look at the car however, the wheel gap is bigger on the front than the rear. The front had a 1/2 Inch gap, meanwhile the rear sat just right on the tire (not literally). Is that normal for KW V3's? The tech that did the work told me that it's normal for the IS-F's to be like that after a drop. I don't see a problem with just raising the rear back up an half inch, but I may be wrong, I am not professional here. I tried searching this forum and didn't find anything..

 

The front wheel gap will be more just due to the fender designs. Just lower it how you want it to look. Are you sure it has kws?

 

Positive, turned the wheels and stuck my head in to look, classic yellow springs with purple tops/bottoms. I live in an apartment and the complex is super strict, they won't allow me to work on my car.. Anyone know of a good place that can just prop my car (if i buy it, lol) up and adjust it for me for a hundred bucks or two? Houston Texas?

EDIT: I forgot to mention, when I test drove the car it rode very smooth, which surprised me, being the way it was sitting.
