Differences between a 993 RS CS and 993 Cup car?

[escobar]

What are the differences between a 993 RS CS and 993 Cup car?

Visually I know the Cup usually has bonnet pins, the X side bars in the roll cage and usually one seat...what else?

Any engine differences?

Also what would you expect to be the difference in values of a good example of each?

Thanks
