I have a ? I want to put some wheels off of a 2003 SC 430 on my 2006 LS430 all the specs are the same except the offset, on the SC430 the offset is between 34-45mm on the LS430 it is between 30-45 is that enough difference to not fit.

 

I don't see an issue, the lower offset means the wheel will stick out slightly more so it could scrub but 4mm isn't that much.

 

Your LS has big brake calipers and this presents a spoke clearance issue. The OEM SC wheels will not fit unless a 15mm spacer is used, the back is fine. With the front spaced 15mm outward the rear looks pretty sunken so you may consider adding some 15-20mm spacers in the rear for visual continuity. The wheels you consider buying should be BBK or high disk fitments.

There is someone else saying that my front calipers are to big for the SC430 wheels ? on my LS430

 

Will a 2006 LS430 18" wheel interchange with a 2003 SC430 18" wheel? both OEM

 

Are they these wheels?
this thread says you'll need spacers
