Just bought a 2006 GS 430 so I thought I'd say hello. First order of business is new wheels - I don't really care for the stock 5 spoke wheels, but I would like to stay OEM and 18" diameter. Forged would be a plus but I haven't had time to research whether such a thing exists. Suggestions are welcome! I will delve into the wheel threads also.

 

Congrats! In my opinion you should go with 19s or 20s. Most of the rims you will like will come in those sizes and they look great on the 3gs.

 

G-spyder or Tourmaline wheels are always a nice OEM option you don't always see

 

You should also post pictures of your new GS when you get the chance

 

I have the oem G-spyders on mine, I think they look really good. I've seen brand new oem sets on eBay for under $1000

 

Spent all day on the road yesterday; trying to catch up. I like the G-Spiders and I've seen the forged F-sport 19s that looks a little strange to me. Both are sold in staggered sets, which I don't need or want, so it gets a little more complicated to get a square set. 19s would require new tires, which doubles the cost, but I'd have 2 full sets ....

 

Congrats! I went with OEM GS F sport wheels on mine.

 

G spyders can be had as a square set as they were sold on the IS AWD model, maybe if you put IS, itll help your search

 

3GS wheel thread has TONS of suggestions, its where I started off and asked about fitment and so on. Welcome to CL!
