I have ran over something and it gave my s2000 a somewhat damages.
I could see that front and rear subframes are shifted backward. I took it
to wheel alignment/frame shop and mechanic told me the subframes where
just shifted backward and does not have any damages to them. I asked about
the lowered drivers side and mechanic told me it must be the springs because
its not oem and does not have anything to do with the subframe being hit and
shifted backward. However, drivers side got lowered after this accident. Is it
possible that when I ran over something, that impact may damaged the springs?

 

Do you have a coilover setup suspension? If you have a coilover setup, it is possibly that the coilover loosen and lowered the car. If not, it could be your shock\strut went dead on the impact? Possibly? Not 100% certain, but a thought.

 

I would start by repairing all known damage.. This way you cancel out everything and will eliminate some guess work. If things are still out of spec then you know to focus on what hasnt been repaired.

 

I do not have any coilovers. Also today I changed oil and when I raised my s2000 I noticed
that even when the wheels/tires are hanging down drivers side tires are at higher location. If
dampers or springs are damaged, when the wheels are hanged down the driver or passenger side
wheels location should be pretty much the same. My friend told me may be the upper or lower
arms may be bent. Anyways I have to fix the subframe to original location, and have check up
for my upper/lower arms.

 

I would check your arms on the driver side, try to compare them with the other side .... checking angles and the joints for anything abnormal. If you dont know what your looking for, you can use the other side aswell.

 

Are you going to do the subframe work yourself? I replaced mine after I smashed into a rock that a dumptruck left for me. There was no space for me to go around it. It was either kill myself by steering left.. Kill the person driving next to me by steering right or brace up and take the impact! I had to pull my EPS, control arms, ground wires and motor mounts to do this. The engine had to be supported as well to keep it from dropping down and ripping hoses and wire harness. Heres some pics from the aftermath.

 

Oh man that looks painful!!!

 

That looks awful! As long as it looks, my subframe is just shifted and has scratch. But how I
got into a accident is very similar to yours. My drivers side tire and even the wheels got crack.

 

Get it checked by a proper body shop and have a word with your insurance company. This could get expensive if the chassis is damaged

 

Thanks for the informations guys! When you install the subframe (F or R) it need to be aligned
using a alignment hole on subfram and the frame. So isn't it possible for subframe to be shifted?
Although, I am thinking that subframe is bent because there is only one bolt that seems to be
shifted. I will look for other frame shop for diagnose.
