Default adjusting coilover length

So I've had my coilovers for over 2 weeks but my rims are taking a little longer to get through customs, so I'm now thinking of getting the coilovers installed without the new rims, and when the rims arrive, then I'll adjust the height accordingly.


My question is: Is adjust the height something I can do myself with just using the regular jack the car comes with (does it even come with a jack?) or one of those simple after market jacks? Or do you need need to get the car up on lifts to adjust?

If I can't do it with a regular simple jacks, then I'll hold off and get it all done professionally when the wheels come in.

Thanks guys!

I prefer changing them at the same time, but you can do the coilovers first and then wait for them to settle before you put wheels and get a new alignment.

You have a good point that they'll need to be adjusted again after the springs settle. Thanks for the reminder!

So the coilover installation will be done by a pro. Would I be able to adjust the height myself later, with just a simple jack that raises one corner at a time? Meaning, will the jack lift the car high enough to expose the part of the coilover that allows for adjustment?

You should be fine doing it yourself.. I adjusted mine over and over again. I dont recommend using a factory jack. That would be murder... you might want to buy a hydraulic jack from Auto Zone or someplace. They are not expensive at all.

You can do it any way you like but if your car is your daily driving, I would hold off on the coilover install until you've installed the wheels. If not, you're going to be chewing away your current tires.

I was thinking of getting a low profile jack. Since it will be lowered and eventually I will have a ground effects kit on it.

Is this one too cheap?

you can get a low profile jack from craftsman at sears... They like 50-60 dollars.

I'm not sure why you are telling me I should hold off.

If it is a daily driver (it's not) and I install them on my current wheels, you say I will wear them out fast. So if I install them when I get my new wheels, won't the new wheels wear out fast too? I don't understand.

You should not have any issues with lowering your car with just the factory wheels. The clearance you set the car with the regular wheels will be similar with the aftermarket wheels unless the overall diameter is different and you went with crazy offsets. Tire wear will vary depending on how low the car will be; which would affect suspension geometry.

I'd have the coilovers adjusted accordingly for each set of wheels (old and new) used.

Going from 18s to 20s, my wheels overal diameter will slightly DECREASE. I think about a 1/4" (can't quite remember how much)

Oh, and I mostly purchased the coilovers for better handling. I would have done it even if I didn't change the 18s out. and i wouldn't have lowered it.

Because if you install your coilovers right now without an alignment, your tires will be eating itself away faster than you think. If you're fine with getting two alignments (one now, and one later), then go for it. Just know that if you do set your ride height now and add wheels later on, you're most likely going to make height adjustments and that affects alignment. If you don't care about your current tires wearing out, then you can install the coils if you want. Since it's not your daily driver, you might get away with it. For those who daily drive, it adds up quickly.

Every year when I switch from my summer wheel/tire setup to my winter wheel/tire setup, I adjust my coilovers (and get an alignment). It's really not a big deal at all; I can adjust the coilovers myself, but since the car goes into the shop for the alignment, I have my guy do it for me. It takes about 5 minutes total once the car's up in the air. (I use Tein CS)

OK, now I understand. It's the alignment that will need to be paid for to have done twice. Gotchya.
