I did my gs-r brake to 5lug brake swap in less than 5 hours. Front to back.

Take the heat sheilds down from the exhaust.
Do the rear first.

Replace the trailing arm bushings while you have it apart.

When putting the toe-arm back on, put it in the middle on the rear.

Have putting the ebrake cables on.

Can I buy your rear drums from the cx?

Invite some of your car friends over and get them to help. It's not hard, just time consuming. Also, PB blaster is your friend.
