So im buying as set of 20 inch wheels from abroad and i was wondering how one can tell that these wheels will clear the IS350 front calipers

the specs on the wheels are
20x9 offset 45
20X10.5 offset 45

Please please please help me out, as there is no way to test fit the wheels and i wanna know if they will fit, it would suck to buy them only to find they touch the brakes and ill be stuck with a set of wheels that id have to sell

thanks

 

i got 19 +45 right now and they dont rub

how does +45 on a 19 relate to a 20? i hear that 20 offset 45 sticks out more than a 19+45, correct?

 

what type of disk face is it, cuz for is350 you'll need a High disk (Rdisk).

 

F 9.0 JX 20H2 E45.
R 10.5 X 20H2 E45.

Whats the code for high disk? Whats the H2 bit mean?

 

umm... good question, i only know the terms for JDM rims if its not JDM then i dunno

 

Thanks anyway Llama, imma try and see if i can get in touch w the manufacturer since no one knows
