I'm buying the 350 & am not sure if I should upgrade the rims to either the G-Spider or ISP mode wheels, or if I should just get the regular stock rims & upgrade on my own later.

I'm not very good at judging how they would look on the car from just a picture of the rims, so does anybody who has them (either one or both) on an obsidian exterior IS mind posting some pics, so that I can get a feel of how they actually look on the car?

 

For the price you'd pay in dollars and weight, you can do much better aftermarket.

 

Absolutely go for aftermarket. Having a much lighter wheel than stock will dramatically improve the driving experience. Factory rims also cost way too much. The OEM 17" and 18" alone are over $500 a piece not inclduing the center caps at $20+ each.

 

I've got upgraded lexus wheels on mine, but I don't remember the name of them. I like them a lot, and everybody that sees the car comments on how they make the car. The main thing is that I like them a lot...

I've just had bad experiences with aftermarket wheels, after a while they just don't look like they did when new. OEM wheels tend to keep their looks without much upkeep. That's my .02

 

Those look like the ISP Mode wheels, fyi.

 

Those rims are much classier than the 17" 10 spoke I initially had. I do agree that most OEM rims maintain their look and hol-up much better. My MOMO's finish chips easy.
