I just lowered my 08 GS with TTE springs (25mm front & rear) and the front camber is @ -1.2, the specified range is between -1.1 & 0.4. The rear is @ -1.5 and the specified range is between -1.9 & -0.4. Much better than I anticipated. I realize the inner will wear quicker but how much is the question. I'm able to rotate front to back and how many miles can I expect to get out of a set of performance summer tires with a tread rating of 300? Thanks in advance.

BTW I had the tsb done for dash rattles and not on sound so far. Actually its tighter now than it was when I drove it off the lot.

 

Well tread rating doesn't mean jack because all the tire companies may use different ratings. So one tire that has a rating of 300 might be better than someone else's 400. What brand are your tires?

 

Yokohama S.Drive Ultra High Performance Summer Tires.

 

I have falken fk452 with the same tread wear rating and Ihave gotten 18K out of a set, and my car is ower than yours. I am actually changing them a little early because I will be doing some extended driving over the holidays. They are good for at least 20K . I dont rotate my tires because they are staggered so you may actually get a decent amount more then 18-20k miles

 

Thanks for the info...20 k would be better than I expected. I was a little nervous prior to the install but after seeing it & driving it I couldn't be more pleased. A little negative camber and 1'' lower makes it feel like it's on rails.

 

I am also very happy. I knew when I got this car that it had ride quality to spare. lol. The tech who did my install said that we dont out of spec as easily with the better in the lexus. The tech said if it was a chrysler 300 1" drop would kill the tires
