To tell you the truth, I haven't even driven the car since the wheels have been on. As far as the tracking is concerned, that is to believe expected. When i put my previous wheels and tires on, 255/18, I noticed that it tracked differently. Now with the even wider tires, it should be even more profound. Although you get used to it in no time, I know I did. With tires this wide, it will definitely follow every groove in the road. That is the price you pay for performance. About the shaking, that sounds like a balancing issue. If you were like me, you had the weights placed behind the wheel, right? You can get a fairly decent balance like this, but not as perfect if the weights were used on both sides. Another trade off, this time for looks. Concerning the center caps, I would contact Ronal directly, for what we paid for these wheels, they'll probably send you some new caps. Oh yeah, lets see some pics. I want to see my car's twin.

 

I would post pics but can't figure out how to do it. I tried and it said file to big. I'm not good with computers. The center cap thing bothers me, i thought i would just glue them back on. Don't know what type of glue to use. Yes i did have them put the weights on the inside also.

 

Lets see if I can help you post pics. First click start. Then find the file where you have the pictures stored. Then find the picture you want to post. Right click on the picture. Click edit. Then you can click edit when you get to the next page. Make the picture around 550 pixels. Then click resize. Then click save. Then save as. In the pop up window, give the picture a name and make it a .jpg file. Then click save and you should be ready to post. Then go to the site again and browse for you pic again. Let me know how you make out.
