I just wanted to make sure that my assumptions are correct. The GS400 and GS300 are basically exactly the same besides motor. The reason I'm asking is because the ebay seller said the rims would fit a GS400 with no problems(even though I asked him if they'd fit on a 300). I don't think that there's any difference in the wheel wells. The rims are 20x8.5 and 20x9.5 with an offset of 20mm and 25mm. Any help?

 

suspension/brakes/wheels/etc are the same.

Yep, search button is your friend... Motor and i believe some of the packages are different...

 

One of the things that comes to mind is the E-shift. The GS400 had it but the GS3 didn't have it until the 2001 model year.
