Will 20" wheels for a 2001 STS fit a '94?

Will 20" wheels that fit a post-'98 STS also fit my '94 SLS? 
 
Thanks.

Wheels will work. You will need watch tire diameter and width, to prevent rub 

That means you can go wider in the back than in the front. But that would prevent you from rotating.

will fit like a glove
