I'm 17 and am trying to learn how to work on cars and I want to lower my 1990 Honda Accord but about an 1.5 inches above the rear tires is some kind of bar (circled in the picture above). The new parts I purchased for this car is supposed to lower it around 2 inches. I was wondering if I need to do something about that bar or if I put the new shocks, struts, and lowering springs will somehow adjust that bars height. If I lower the car 2 inches and that bar is sitting 1.5 inches above the tire will that bar will end up sitting on the tire?
I would like to know what that part is called and what I might have to do or buy to be able to lower the car or if I don't have to do anything and I just install the parts?

 

That is part of your rear knuckle. If when lowering the car the tire comes in contact with that, you have major issues.
The part bolted to the car is the rear upper control arm. That will need to be shimmed at the two bolt mount to correct for camber when the suspension is lowered.
Take off the wheel and you will see how the parts interact and cannot make contact with the tire/wheel through suspension travel.

 

@MAD_MIKE Can I do this by myself and is there any way you can explain a little more in detail what I would have to do and what I would need or maybe find a video to link?

If anyone can explain to me what I can do or buy or share a video of someone doing it that would be amazing, Thank you.

 

That is the rear upper control arm. No modification to it is required when lowering the vehicle.

 

I would replace that upper control arm when lowering the car just cause of the bushing condition.

 

Can also just replace the bushings themselves. If going that way, you'd want to consider polyurethane cause lowering can do a number on your old rubber bushings

 

@Aradin so will it somehow adjust to the new parts? I don't understand how lowering the car 2.5 inches will not end up touching that part if it is only 1.5 inches above it.

 

Lowering is easy on these cars, but you will need to get a shim kit with longer bolts for the rear upper control arm, and for the front adjustable upper control arms to bring camber back.
There should be an article in the FAQ at the top of the page.

 

Hey Friend! Glad to see your modifying a CB Accord! What you have circled in your picture is your Rear Upper Control Arm. When lowering an Accord with that style Upper control arm you definitely should consider installing an adjustable type control arm so that you can properly align your car after lowering. If you are on a strict budget you can use washers but I wouldn't advise with the wear on your current arms and they only can correct about .5 degree of camber. I would recommend SPC Performance (same manufacturer as Eibach) EZ Arms Part Number: 67065, you will need 2. They are currently 86.99 each on summit racing. If you are planning on lowering more than 2in. I would get Part Number: 67265 by the same manufacturer. Also not to divert traffic from Honda-Tech, but CB7Tuner.com has very in-depth threads about anything you could think about on your Accord chassis. Check it out sometime! Happy modding!
