Default Setting Suspension Height on uneven ground

I know this might be a stupid question, and I personally cant think of an accurate way but I thought I would give it a shot.

Is there a way to set suspension height when the ground below the car is not even? I've heard of people putting wood under the tires until the car sits level, but that would be tedious I would think?

why not take your car to a place where the ground is even and do the job there? Doest have to be at a shop, can be at any buddies house...

Simply match the perch position left to right. Count threads if you have to. You don't want to unbalance the car more than stock, and without scales the best you can really do is match perch height.

Thats what i've been doing for some time now, but just recently adjusted a set for a buddy of mine, and they came out uneven. I'm assuming due to bushing condition maybe? But any place I can work on a car has uneven ground so i can only guess-timate about where it should be.

I'm just afraid of possibly causing some condition where abnormal tire wear becomes a factor. Thats my main concern.

It could be bushings. However, was your car level, left to right, stock? If its a FWD Honda, then no, it wasn't.

Our transverse engine FWD cars do not have an equal left / right weight distribution. With equal perch settings, the car won't sit level, and didn't stock.

However, if you raise the spring perch on the heavy corner, raising that corner of the car, you'll be forcing that tire to support even more weight than it already was (could cause more tire wear on that corner), and will further debalance the car. If you put the car on scales and do a proper corner balance, they will lower the heaviest corner even further, to redistribute some of the static weight off that corner.

Cosmetically, you might want the car level. However, no one is going to see both sides at once to tell, and it will hurt handling to do so.

That makes perfect sense. I never considered those aspects you mentioned in regards to the car sitting even from the factory. Thanks for sharing that info!
