I haven't found anything concrete regarding my question so if I missed this topic somewhere my apology in advanced for the redundancy of this thread.

My question is for a LS430, ideally the newer years 04+, could you upgrade the stock rim to one of the new 2013 LS460/600hl rims for the new tech with sound dampening channels? I've seen LS430s on 20's so I figured unless I'm missing something they should bolt right on right? Thought this might be a way to make an already quiet car even more superb?

 

I don't think they will fit. The LS460 uses a different bolt pattern than the LS430/LS400.

The 2007-2012 LS460/600h uses the 5x120 bolt pattern if I'm not mistaken where as the LS430 is 5x114.3. The 2013 model most likely is the same as the 07-12.

 

Kira is correct, the bolt pattern is different. The expense for adapters would add an additional ~$140 per axle for the conversion and you'll be looking at a 25mm change in offset. If lowered, you'll likely need fender mods.

 

I wouldn't want to lower the vehicle any lower than the stock suspension allows. The whole idea was to make the car as silent and comfortable as possible. I know the LS430 is rated a nearly silent ride, but adding these sound dampening rims would make it even more quiet right?

Would I need a fender mod like you mentioned with the stock suspension ?
