Question Adjusting Tein Coilovers

I am new to coilovers and have a few questions about adjusting the Tein comfort sport coilovers.

Coilover experts please advise.

Damping:
What damping setting should I set the front and rear if I am looking for improved handling were the car will behave neutral around corners. (ie. not oversteer and not understeer)
I am not concerned about ride comfort.

Height:
From Tein's website, the ISF comfort sport have the following settings
Front drop is 1.2" (min = 0.2" max = 2.2")
Rear drop is 0.6" (min = 0.3" max = 1.1")

- Why is the the front drop more than the rear? Shouldn't the drop be even on 4 suspension?
- Besides the wheel gap might look bigger in the front than rear with an even drop, are there any other disadvantages compared to a lower front than rear?
- If I want the max even drop, then I should drop 1.1" front and rear ?
- I am planning to drop the same height on the front and rear because I plan to put a front lip and don't want to the front to be too low.

Any advice is appreciated. Thank you.

The rear is always lower than the front just a little bit, so if you want to lower it to the max, you have to lower both to the max

When it comes to dampening, I feel the best adjustments are usually made through trial and error. It will take awhile, but you will eventually find what YOU want from it.

I have mine set at 15 our of 30. Seems to be the best for comfort and handling for everyday driving. Just lower it to what you think looks the best, make sure the left and right on the front is the same height on both sides and same for the rear, if you can, corner balance it for perfection.

It all depends on what you're trying to achieve. Ride height determines suspension geometry. We know the front of the F was raised from ideal to clear parking stops, so the front needs more drop than the rear to get to a better set of camber curves. But at the end of the day, there are two types of performance - visual and mechanical. Visual performance compromises mechanical grip, mechanical performance compromises visual performance. You have to decide if you want to look good, or have better grip.

Damping is related to spring rate and ride feel. Again, mechanical performance might not feel good, but performs better when grip is the ultimate desire. You'll have to decide what you want before anyone can say what will work best because best is a relative term.
