put the seat backs down in the back and lay them flat on the seat backs with drivers out of bag.....I like to push the passenger seat all the way back to stop them fom sliding forward in a short stop.....

warning...it you have a stand bag pull the clubs out from the top of the bag, ive had the bag stand 'open' on me and it can get caught up on the seat belts, etc.....kind of a pain.
