I have a GS400, when im in the rain the steering starts to vibrate between 56-60 mph, ive had an professional alignment done , tires balanced, and changed tire type from MIchelin pilots, to Perrelli P-0's , same thing. I don't remember if the car did the same thing with the stock rubber, and rims. Im running Volk AV_3's 235/35/19 frt and 275 30/19's in rear. Has anybody had similar vibration. It's only in the rain , in dry the car is stable as a rock, right up to a 155 mph.

I had the same problem with my GS400. It would vibrate real bad in the rain. But like what you said its cool as s### on the dry pavement. Since I have gotten my RIMS fix I have not felt a vibration just yet but it has not rain all that hard yet. I have 18' inch MHT V10 with 235/40 18 in fr and rear is the exact same tire size. I'm using Nitto 555 extreme's. But, I wanted to switch to the Toyo T1-S proxies. So, I really not sure what your problem is but check the RIM out...

Some aftermarket wheels require centering rings to fit the GS properly. Check around to see if your wheels require them, if you don't have them already.

Where can I get the centering rings from? I have no clue where to go. I check with a couple places and nobody had anything to offer...
