Default Suspension is a little off

My driver side of the car seems to sit a little lower then the passenger side. The car was driven with 15x6.5 +45 while the passenger side was 15x7 +40. Would this be my problem?

even after remounting and rotating the wheels with +40 on the front and +45 in the rear the car sits lower on the driver side. I have no clue what is causing this unbalanced suspension.

Cliff notes:
Car sits about 1-2 inches lower on the driver side compared to the passenger.
Driver side Passenger Side
Front offset +45 +40
Rear offset +45 +40

Swapped the shocks from left to right and the shcoks are in good working condition.

Tried to adjust the height with the coilovers but still no go.
Driver side:
Lowered to about half the coilsystem
Passenger side:
Lowered about 1.5 inches more then the driver side

And still the passenger side is sitting higher.


Added notes, After taking apart suspension and peicing it back together there was about 1.5 finger gap but this morning the car has sagged and the wheels are tucking.

Have you installed anything suspension-wise on your car? Your wheels with same diameters won't affect ride height. The offsets only affect lateral position of your wheels, not ride height either.

It'll be either your springs (maybe unseating?), or bushings, or maybe failure of a control arm. Take the tires off and do a bit of investigation work underneath.

it was originaly on Koni yellows but the shocks were blown. the car was sitting like this for about 6 months (4000 miles). When i go over bumps the driver side seems like it bottoms out, like no shock travel but the passenger side is set at the same settings.

Aside from an inspection (doesn't sound like the shocks, unless they're binding - getting any weird noises other than bottoming out from the front driver's shock?) of your suspension, maybe you can swap the two front struts and see if that transfers the droop. If so, you've got a bad shock (or spring - but I can't imagine how those would go bad).

Havn't been able to check out the car underneth and all but it seems as if the shocks are bottoming out.

any other affects of driving with +45 offset on the driver side and +40 on the passenger side?

I just realized you have one offset on the driver's and another on the passenger side. What I get for not reading closely.

Why are you running your tires like that? I'd at least do a front/rear asymmetric layout.

But again, different offsets shouldn't give you the symptoms you're getting - we're only talking 5mm. Swap the struts forward and see what happens...

Walmart didnt read my comments on the paper and just mounted them. i recently got it fixed but now its the suspension drop issue im dealing with.

are struts swapable from left to right?

Probably not if you have a car that actually has struts (never looked at the struts to see). Is this on an 01+ Civic? If you have a double wishbone car, then yes, the shocks (can't have struts with wishbones) do transfer from side to side.

However, you have to realise that most Hondas are lower on the left side stock, because the transverse engine is not centered in the engine bay. When the weight isn't split 50/50, the car won't sit level with equal springs.

I tried to adjust the height with the coils but the left(passenger side) is nearly all the way down about 4 more coils till the end, but the left side is sitting higher then the right.

Left side coilovers are almost down
Rightside coilovers are half way down.

but the left side sits higher.

This is a 95+ 4dr integra. Never had this issue before, i just got home a few weeks ago and it sat a little lower then usual on one side.

yes the sides are interchangeable. whats the spring and shock combo? Might have sagging issue with the springs and the fact that the shocks are blown.

It sounds like you have a blown shock, a worn shock bushing, or the coilover sleeve is not seated correctly.

The tire offsets will not impair your ride height that much. As you've already tested, swapping the tires did not change the difference in drivers and passenger side heights, the issue still appeared.

the car was sitting in my garage for about 6 month (4000miles driven) would that have prematurly affected anything?

The suspension is Tanabe Sustec Pro

The coilovers are in working condition.
Just swap the left to the right and it does the same thing. I dont know if my left side is sitting lower then usual or if my right side is sitting higher.

Say there are about 80 threads on the coilover:
The left side is at about 35-40 while the right side is at about 8-13 threads from the bottom.

Even with this uneven thread setting, the left side is sitting lower then the right side.

Ok, scratch the coilovers from the equation...

I'm assuming a blown shock or a worn control arm bushing. If you have the time, remove the left shock and completely disassemble the coilover sleev from the shock. Then put the tip of the shock against the ground and compress the shock, pushing into the ground from the bottom of the shock. Then feel if its leaking, if its good, and if it rebounds on its own once you push down on it and flip it over to its original state.

Did that and they seem to be in perfect working condition. Any idea what bushing it might be?

So once you compress them, they somewhat smoothly and quickly expand back to normal height? They shouldn't take too long to return back to full lentgh extension.

The bushing I'm referring to is the rubber one you connect the shock fork to the front lower control arm.

Are you positive the top hat of the shock is seated on the top of the spring correctly? Maybe its shifted? How's the ride quality at this current stance?

You know what, I'm retarded for not reading more carefully...

OK, but after reading, I'm going to list a couple of things it can probably be -

-Did you reset your bushings after swapping the suspension? This requires you to loosen all the bolts that are holding suspension pieces and go through a rubber bushing of some sort. Once loosened, you need to jack up that suspension arm until that side is just slightly lifting off its jack stand, tighten the bolts down, and lower the side back down.

-Read previous response about the bushing location

Cliff notes:
Car sits about 1-2 inches lower on the driver side compared to the passenger.
Driver side Passenger Side
Front offset +45 +40
Rear offset +45 +40

Swapped the shocks from left to right and the shcoks are in good working condition.

Tried to adjust the height with the coilovers but still no go.
Driver side:
Lowered to about half the coilsystem
Passenger side:
Lowered about 1.5 inches more then the driver side

And still the passenger side is sitting higher.

Added notes, After taking apart suspension and peicing it back together there was about 1.5 finger gap but after about 3-4 days later this morning the car has sagged and the wheels are tucking.

Sounds like the shock fork wasn't tightened adequately. If the car is sagging after you've tightened everythign up, something is slipping.

Default Re: (TunerN00b)

maybe you stroke your car to much so it tends to lean to the left a little bit???
lol
honestly if you are still using the same springs from when you were driving around with blown shocks and or struts they might have cause your springs to loose strength or viscosity on the driver side causing the car to droop on one side more than the other
or a blown shock and/or strut will do it occasionally but i dont think from a shock being blown that your car is going to lean this much to a side sounds a little bit to much for me
id check your suspension components since your lean is this bad i wouldnt factor out that you did something to your car causing something down there to bend giving you a lean but iunno just my 2 cents hope all goes well for you GL
