G-20 uprights?

[madsnowshoveler]

I've read that the G-20 got an improved, cast alloy uprights, along with a rack relocation to improve handling dynamics. I'm looking to buy used, and need to know how to determine if the cars I'm looking at have the new setup. Here in America, sellers list "competition suspension upgrades" as a feature. Is this the new upright or just stiffer suspension?

Thanks for your help!
