I may have to go to Q&A on FIRST.
Here is something to keep in mind for mounting bumpers in general, but especially on shorter bots:

Make sure that your standard bumpers can simply and securely attach to your chassis in the bumper zone with reasonably sized fasteners. Incorporate the bumpers into your design, don't wait till the last minute to to find a way to attach them.

As an inspector last year, I saw 1 or 2 teams that needed some sort of metal bracket to fit the bumpers in the right place vertically. The teams thought these brackets would be counted in the weight of the bumper, but the brackets are part of the chassis and counted against the weight (and size) of the robot. Many other teams simply mounted the bumpers several inches outside of the bumper zone (between 2.5" and 8.5") because that was where it fit easily on their chassis.

With bumper requirement this year many teams will be building them for the first time. Don't make bumpers an afterthought because unlike last year you can't just take them off if they don't meet requirements.
