I haven't yet. The Gnosis are still on my LS430 at the moment. I have new wheels coming for the LS430 and don't know what to do with my current Works. I'd prefer 19's on the GS and have a few wheels in mind, likely Work or GMR wheels.

 

I ended up picking up some 20 inch Works that my friend had on his wife's GS350. The front specs aren't quite as aggressive as I would like for them to be due to the GS350 having large front brakes. I'll throw them on my LS430 until I can get coilovers for the GS.

The specs on these wheels are almost identical to my old Work Gnosis wheels so they should be pretty flush on the GS and LS. I really wanted 19 inch wheels to run meaty tires. I'll have to try to find some side skirts and a rear lip for the GS.
