I received my car back from the shop today and the rear is sitting lower than the front.

Could the shop have put the wrong springs on the rear and the front?

It is possible since the labeling on the springs is not very good and the instruction don't specify which goes on the front or rear. I had to call Tanabe to confirm and what they told me is this. There should be a number on the spring that will end with NR (rear) or NF (front). You should be able to locate this without taking it back to the shop or taking your tires off (or you can take the tire off for ease if you want).
I installed mine with the help of a mechanic friend and we noticed that the OEM spring was taller in the front then the rear so logic would tell you that the taller tanabe spring should go in the front and they might have used that login when installing yours but that logic didn't compute with me since the tanabe springs were supposed to lower the front more than the rear so I put the shorter spring in the front and was correct. Good luck.

ghd8989, your stance with tanabe nf210 springs should look similar to mine (i assume you install NF210s and not DF210s?):





if your GS450h doesn't look like mine, then you may have a problem.

omg, gosh.... this doesn't sound good.... so the shape of the front/rear springs look more or less the same? that's pretty "dangerous"....

Ok. I have a problem then. I will check for the spring code now and update

This is what you are looking for:

I was just about to type you to see what it should look like. I think I need to remove a tire to see.

Yeah, it depends on the position of the spring, I had to look at each corner to see which one had the number visible and got lucky and found one so I didn't have to remove a tire. GL keep us posted.

Ok. They say R in the rear so maybe they settled and the fronts haven't. Hmmmm. There is not wheel gap at all though and I will have to grind down the fenders before I can even drive it again. So weird. My camber is also at -3 in the rear. Is that normal? I am running a 285/25 in the rear.

Then they are installed correctly. Your rubbing? Are these the NF or DF, what is your tire and wheels spec? They did settle after a couple of weeks. Here is what mine looked like after installing them:

I ordered NFs and they are red like yours so NFs. I have a 20x9 front 245/30 and a 20x10.5 285/20 rear.

Did I order the wrong spring?

No it's the right spring just curious as to why you'd be rubbing in the back, as you can see by my pic I still had considerable clearance. I know that your running a wider rim and can only assume you have a pretty aggressive offset to contribute to the rubbing.
Well give it some time to settle and then you should see the front drop. Post some pic of your ride tomorrow.

ron, after your car settled with the NF, do you remember if the rear wheels are tucked or you still had wheel gap? how about the front? i would imagine it shouldn't settle significantly over time.

Henry,
I still had wheel gap but it did settle quite a bit (imo), I posted another comparison pic that was taken after a couple of months of riding on the NF. You can see in the pic less wheel gap.
