because one side is lower than the other and i don't want to pay another $100-120 to have it realigned?

you should lower the other corner by 1/4" instead

I wouldn't get an alignment for a 1/4" adjustment though, unless the steering is completely off, which I doubt.

only 1/4" should be ok. just realize that if you adjust one corner, it will usually affect the the opposite corner of the car (changing the front right can affect the left rear). So you can go crazy going around the car, chasing quarter inches.

Also make absolutely sure you're measuring it on a really flat even surface.

I had it in my head that my rear left was almost an inch higher, no matter where I was at. Took it into the shop, measured it again and it was dead even...

Driver side should be slightly higher so when you get in, it levels out.

nah, raising one side by only .25" wouldn't affect any other corner at all.....trust me. Unless all of them are off to begin with. Just measure from the bottom of the lower perch to the bottom of the last thread on the coilovers using a measuring tape.....Had to adjust mine a couple days ago by about .25" or so.....I also made sure all other corners measures up after the adjustment, and they were all fine, no movements. Just make sure you super tighten the perches to the point they absolutely DO NOT move when trying to turn the springs......I mean, SUPER tight!

Yup... I used to do it all the time, 1/4" to 1/2" should be good to go..

That's why it is better to measure from the suspension itself, rather than from the bumper to the ground.....For this very reason.

It will definitely change the alignment. Maybe not by much... but it will change it. Where do you draw the line on how much of a height adjustment you have to do before it warrants an alignment?

The change will be negligible IMO, plus, I think OP can always take it to an alignment shop and see how out of spec they are. If they're just a tad bit, and he can't feel the difference on the road, then he probably don't need to get it redone.

Unless he went to Firestone for an alignment, in which case, they offer a life time alignment for the price, no?

If your car is too low to fit the jack, how do you even adjust the height to begin with?

Either go to a shop with a lift or buy a piece of 6x10 and drive onto that to get enough clearance....then jack up the car.

You forgot about what I wrote in my first post? I took it to the shop thinking the height was uneven. Obviously I wasn't adjusting it at home.
