I picked up 1990 GSX calipers today for $30.

I just have a few questions. I have searched but could not find the answers.

1. Are the 1g and 2g front gsx calipers the same size?
- I did not think so, but not sure.

2. Will the 90 gsx calipers bolt up on the rear instead of the drums on a 1996 rs?

3. Are the 1990 gsx calipers any better than the facory rs ones?

4. Has anyone upgraded to the gsx calipers in the front and moved the front ones to the back to replace the drums ? Could this be done? Is it worth while?

Thanks in advance and sorry if this was covered and I missed it in the search.
