So here's the deal (btw, if this should be in wheels/tires, mods please feel free to move this):

I have stock oem shock/springs. I have oem fitment Advan RGIIs, and recently bought new tires - Yokohama S-drives, 245/45/17 and 215/45/17. I now rub in the rear when I go over bumps, or if I carry more stuff in the trunk.

Any ideas? The only odd thing is I went from 245/40/17 to 245/4517. Would that alone do it? Should I take it in? It's been going on for about 4 months now...

Thanks!

 

well thats gonna increase your overall diameter in the back
but idk if you should rubbing since your ride around at stock height

a 45 is a big difference really and depending on the brand you could have a bigger 245/45/17 tire vary in size like a shoe all brands are different i say go back to the original size it is odd though

 

number of thing

1)at 45, your rear wheel OD is bigger than original. the bigger question is why you do that in the first place.

2)newer performance wheel are almost wider than older design, adding more rubber to the width is a cheap way to add more "stickie" to a tire without changing the compound.

3)offset of your rims

if you know your damper is damaged, is there any reason not to fix it?

 

Add more negative camber or roll the rear fender lip.

 

you prolly have a shock blown. i have the S-drives and i have 255-40-17s on the back and i have about a 3 finger gap.

 

thanks guys - I'll probably go in and havesomeone look at it. My best guess is that since I switched brands, I may be rubbing now, and since it correlated with the tire switch, it may not be a blown shock - but I'm gonna check.

 

Definitely the wrong tire size back there, but at stock height I still don't think it should rub. How many fingers worth of gap do you have in the back now? I asked about putting 245/45/17s back there once and even the Tire Rack guys said don't do it. I was interested in doing it specifically to shrink the wheel gap without lowering the car. The funny thing is, even if the wheel gap is smaller you have effectively raised the back end of the car
