I am looking at a set of SSRrims, the size is 18x9.5 for front and rear. The offset is +21mm. I am going to install H&R lower springs on my IS350 which is going to lower 1.4' in the front and 1.3' in the rear. I am wondering are they gonna rubing? And the factory offset for 2006 is350 is 35mm-45mm. Can anyone help me with these problems? I really like the rims just worry aboout the fitment. Thanks

 

1. the front fenders will need more work than the rear fender, but you're looking at rolled fenders + natural pull + deleted fender tabs. that's not to mention the need to run slightly-stretched tires.

2. specs for the oem 2is 18's are 18x8 +45 and 18x8.5 +50. don't know how you got those specs.

 

Sorry for the late reply. I am thinking what is the max for my lowered is350. It is going to sit on H&R lower springs. So I have no idea about how to choose rims and tires. The ssr ones are currently attractive for me.
