The wheel weights always seemed kind of random to me, although I'm not fond of how all the ugly ones are the heavy ones. A decent-looking five-spoke wheel that was really heavy would help my PI stacking endeavors greatly. 
I've looked for lighter rims for my real world Miata and the light rims in the game tend to be the lighter rims available in the real world. I would like to see different OEM rims that were available on the different cars. The in game 2001 Mazdaspeed has my style of rim, but mine are 16" and silver.
My biggest problem with the ingame selection is that too many rims look too similar, more variety would be nice. And, like a lot of the daught netters, I would love be able to paint rims non-metallic colors, white, yellow, red, etc for rally style paint schemes.
